DESCRIPTION
Procedure and apparatus for forming a mesh
Field of the invention
The present invention relates to a method and apparatus for the formation of meshes using molded interconnecting joining elements, an example of such a method and apparatus being known from US-2 752 636. When using the The term "mesh" in the present specification means a mesh formed by interconnecting attachment elements, such as rings.
Background
The mesh formed by interconnecting joining elements is better known in the form of a chain mail. Chainmail has traditionally been formed by interconnecting closed metal rings with open metal rings and then closing the open rings by a process such as mechanical deformation, welding etc. In another method, split rings formed of spring steel or some other elastic material are used as interconnecting joint members and are temporarily opened by a tool, such as pliers, to allow interconnection to other joint members. In recent times, the mesh has been formed from plastic material by joining closed rings with open rings and then mechanically fixing, welding or gluing the open rings to close them.
Manufacturing the chainmail / chainmail by traditional procedures is time consuming, labor intensive and expensive. Chainmail / chainmail that includes open fasteners may only be exposed to limited forces before the fasteners fail. When the interconnecting fasteners are closed, the hinge can impair the appearance of the finished mesh. Such procedures have also limited the materials that can be used in the manufacture of the mesh and have limited the practical size of the bonding elements.
Although there has been a complex apparatus for forming mesh by cable folding, to date there has not been an automated process for the continuous and economical production of chainmail / chainmail for mass consumer applications.

A further object of the invention is to provide new mesh products and mesh wearing methods.
Each of the above objectives is to be read separately in order to at least provide the public with a useful choice.
According to a first aspect of the invention, there is provided a method of forming a mesh comprising:
to. advancing a first plurality of attachment elements from a first set of locations to a second set of locations within a mold; Y
b. for each successive advance of the first plurality of preformed connecting elements, placing a second set of preformed connection elements in the first set of positions and casting a plurality of new connection elements in the mold through the first and second pluralities of preformed connection elements that are positioned in the first set of positions and in the second set of positions to interconnect the first and second pluralities of preformed bonding elements that are positioned in the first and second sets of positions with the new tie elements to form a continuous mesh of interconnected tie elements.

Detailed description of the invention
One embodiment of the present invention includes a mesh forming process in which the elements
The attachment may be in the form of disjointed closed loops. However, the fasteners can take many forms, including shapes that have a single opening therethrough, such as rings, shapes that have multiple openings, and so on.
Referring to Figure 1, a process for the continuous production of meshes is described. The preformed rings 1 to 4 are arranged in a first orientation with pairs 1, 2 and 3, 4 arranged so that the portions of their central openings overlap. Other such pairs may be provided in a row at spaced intervals in the plane of rings 1 to 4 to form a mesh length as required. A ring 5 can then be molded to pass through the center openings of rings 1 to 4 as shown. Ring 6 illustrates how additional rings can be formed simultaneously along the row.
Referring now to Figures 2 and 3, the production of a subsequent row of mesh is described. Ring 3 of Figure 1 assumes the position of ring 4 of Figure 2 and ring 1 of Figure 1 assumes the position of ring 2 of Figure 2. Ring 5 of Figure 1 assumes the position of ring 7 of Figure 2. The new rings 3 and 1 are inserted in the positions shown in Figure 2. A new ring 5 is molded through the central openings of rings 1 to 4. In this way, it will be seen that by sequentially introducing a new row of rings 1 and 3 and molding a new ring 5 through new rings 1 and 3 and the old rings 2 and 4 can be made a mesh continuously. It will be appreciated that this pattern can be extended in any direction until the desired mesh width is obtained.
Referring now to Figures 4 and 5, a cross-sectional side view of a basic mold for forming a continuous mesh will be described in the context of the arrangement shown in Figure 3. The mold is made up of the mold sections 9, 10 and 14 and finger 13. Mold sections 9 and 10 start at mold faces 9b, 10a and mold sections 9 and 10 start from finger 13 at faces 9a, 10b and 14b. The annular cavity 12 is dimensioned to retain the ring 2 and the annular cavity 11 is dimensioned to retain the annulus 1. The relative spacings of the components, indicated by the letters B, C and D are indicated respectively in Figures 2 to 4.
A finger 13 of semicircular cross-section defines the middle of the central opening of the ring 5 that is formed in the cavity 15. Plastic materials can be introduced into the mold, when closed, as shown in Figure 5, to form a ring of 5 in cavity 15. Mold sections 9 and 10 can then be moved to the left to open the mold with finger 13 raised up and mold sections 9 and 10 are separated from free ring 5 molded in cavity 15 .
To form the next row, the ring in cavity 11 is moved to cavity 12, a new ring is placed in cavity 11, the mold is closed as shown in Figure 5, and a new ring is formed in cavity 15 It will be appreciated that Figure 5 shows a section of a mold that can be repeated throughout the mold to form a continuous mesh row. Referring now to Figures 6a to 18, an apparatus for the production of continuous mesh is described. Figures 6a to 6c show the main components of the apparatus including mold sections 30, 31 and 32. Mold sections 30 and 31 can be separated from mold section 32 as seen in Figures 6b and 6c. A plurality of fingers, one of which is indicated 37a, moves with the mold section 30 and can move vertically relative thereto. Mold section 30 is movable relative to mold section 31 to allow molded fasteners to release as shown in Figure 6b. Arm 33 is connected to bar 34 (shown in Figure 7 and below) that raises and lowers fingers 37a as roller 35 is guided into slot 36 and section 30 moves out of section 32 .
Referring now to Figures 7-11, a portion of the working faces of mold sections 30 and 31 is shown. These working faces can be extended to the left and right as required to form a desired mesh width. A plurality of fingers, of which only 37a to 37d are indicated, are attached to bar 34. Bar 34 is connected to arm 35 and raises and lowers fingers 37a to 37d as roller 35 moves on the track 36. Figure 9 shows fingers 37a to 37d in their raised position, while Figures 7 and 8 show fingers 37a to 37d in a lowered position.
Preformed rings are supplied to the apparatus through supply tubes, some of which are indicated by numbers 43a to 43e. Referring to Figures 12 through 14, the shape of fingers 37a through 37d is shown. Finger 37a has partial annular cavities 39 and 40 on the posterior face 38. These cavities 39 and 40 are positioned so that when the fingers 37a to 37d are in the raised position shown in Figure 9, the rings supplied from the supply tubes 43a to 43e may be located within the partial annular cavities 39 and 40. of the adjacent fingers. Recesses 39 and 40 include biasing elements 49, which push the retained rings within them away from recesses 39 and 40. End 42 of finger 37a engages bar 34. The distal end 41 is scalloped to aid product exit from the mold.
Referring now to Figures 9 and 10, the working faces of the mold sections 30 and 31 include cavities 45a to 45e to house the preformed rings and cavities 44a to 44e to house the overlapping rings 45a. at 45e. Ejector pins 48a through 48e move in and out in a direction normal to the page to assist in ejection of the rings, as will be described later. The
ES 2 394 491 T3 ejector pins 48a to 48e include recessed sections 47a to 47e that house rings within cavities
45a to 45e when retracted.
Referring now to Figure 11, a view is shown along line BB (see Figure 10). It can be seen to see that the semi-circular cavities 46a to 46e are provided with a normal orientation with respect to the working face of the mold section 31. Semicircular projections 55a to 55e defining the half of the circular core of a ring extend from the mold section 30 such that when the mold is closed, the half of an annular ring is defined by the cavities 46a to 46e and the projections 55a. at 55e.
Referring to Figures 15 to 18, the working face of the mold section 32 is shown. A plurality of semi-circular cavities 51a to 51d form the other half of the annular cavities that form the molded rings. Fingers 37a to 37d are located within cavities 50a to 50d, with fingers 37a to 37d defining one half of the core of rings formed in the annular cavities (the other half being formed by projections 55a to 55e). Injectors 53a to 53d (see Figure 18) inject molten material into semi-circular cavities 51a to 51d through openings 52a to 52d during molding. In one embodiment, the material is thermoplastic. In another embodiment, the material is metal.
The operation of the apparatus will now be described with reference to Figures 6a to 18. Initially, the mold sections 30 and 31 are separated from the mold section 32 and the fingers are in the raised position shown in Figures 6c and 9 The rings contained in supply tubes 43a to 43e are pushed towards fingers 37a to 37d and are retained within cavities 39 and 40 of the respective fingers. The bar 34 then moves downward as the mold sections 30 and 31 move towards the mold section 32, so that the fingers assume the positions shown in Figure 8. The deflection elements 49 in the cavities 39 and 40 push the rings into cavities 44a through 44e. These rings overlap the rings already positioned within the cavities 45a to 45e.
Mold sections 30 and 31 are then closed against mold section 32 so that fingers 37a to 37d are housed within cavities 50a to 50d (see Figure 6a). Mold section 30 is also pushed back into mold section 31 as the mold closes. When the mold is closed, cavities 51a to 51d and 46a to 46d define a disk-shaped cavity. Fingers 37a to 37d together with projections 55a to 55e define a circular core such that a series of annular cavities are defined.
In one embodiment, injectors 53a to 53d then inject plastic materials into cavities 51a to 51d, so that rings are formed in cavities 51a to 51d and 46a to 46d. Alternatively, cavities 51a to 51d (or another part of the mold cavity for each ring) can be normally fed with the molten material. Mold section 31 is then moved out of mold section 32 (as shown in Figure 6b) and, simultaneously, mold section 30, which is skewed relative to mold section 31, moves away from the Mold section 31 sufficiently to allow the rings formed in the mold to be released from the mold section 30. Mold sections 30 and 31 are then moved further, as indicated in Figure 6c, along with fingers 37a to 37d. As mold sections 30 and 31 move away from mold section 32, roller 35 reaches a section in slot 36 where it causes bar 34 to rise. The bar 34 is eventually raised to the position shown in Figures 6c and 9.
At this point ejector pins 48a through 48e are moved in an off-page direction to eject the rings retained within cavities 45a through 45e. However, the cavity rings 44a through 44e are retained as they are located on top of the ejector pins 48a through 48e and behind the fingers 37a through 37e. Fingers 37a through 37e are then partially lowered as mold section 30 moves toward mold section 32 to retain the rings in cavities 44a through 44e. Ejector pins 48a through 48e then retract and rings retained in cavities 44a through 44e then fall into cavities 45a through 45e. Mold sections 30 and 31 are then closed with mold section 32 and the apparatus is ready for the next molding cycle.
Although the tie elements are shown to be formed in rows, it will be appreciated that other molding arrangements may be employed. For example, adjacent tie elements may be offset relative to each other. It will also be appreciated that the apparatus may be adapted to allow two sheets of mesh to be joined. It will be appreciated that the method of the invention can be implemented in many ways.
After manufacturing, the mesh can undergo additional treatment processes. In the spark ignition process the mesh can be exposed to a high temperature heat source for a short period of time so that minor surface imperfections melt and each bonding element has a substantially smooth surface. In addition, the mesh can be coated by electroplating, spray painting, or some other coating process. Coatings can be applied to provide physical properties or a particular appearance.
The mesh formed by the process of the invention can be further processed to form products. A mesh can be held in a desired configuration, for example, by placing the mesh on a mold, then heating it so that the bonding elements melt and then cooling it so that the bonding elements
ES 2 394 491 T3 joints remain fixed relative to each other forming a rigid structure.
Alternatively, the mesh can be kept in a desired configuration and a curable composition, such as a resin, is then applied and the configuration is maintained until the set material hardens to form a rigid structure.
The bonding elements can be made of various materials that can exist in a fluid phase and then harden, such as plastics, metals, glass, absorbent or non-absorbent foams, flexible polymers, etc. A mesh can contain a mixture of bonding elements formed from different materials. In addition, the optical characteristics of the bonding elements can be varied on the mesh to create a particular pattern or visual appearance. For example, different patterns can be created using tie elements of different colors and / or transparent tie elements.
The joining elements can also take a variety of forms that can be mixed with a mesh. Some examples of closed-loop fasteners are shown in Figures 19A through 19H. Other novel shapes, such as hearts, etc. they can be used too. In addition, the fasteners may have patterns or indicia molded into their surfaces.
Figure 20 shows another form of attachment member in the form of a circular disk 66 having a plurality of apertures 67 to 70 provided therein. Rings or other tie elements can be formed through openings 67 to 70. It will be appreciated that a wide variety of tie element shapes and configurations can be used, as well as traditional mesh arrangements using tie element designs 1 : 03; 1:04 or 1:06.
The mesh formed by the method or apparatus of the invention can have use in a wide variety of applications including: filtration, contamination control; signage, flags, screens, etc .; conveyors; deflectors; armor, clothing, furniture, such as hammocks, deck chairs, etc .; screens, curtains, etc.
The mesh has been found to be particularly effective in collecting materials, such as oil, from the surface of a fluid, such as water. A mesh formed of tie elements formed of absorbent material or that includes links formed of an absorbent material can provide additional capacity for oil collection. The screen can be provided on a drum or as part of a conveyor system so that the collected material can be continuously removed by a washing or squeegee system etc.
A fast and inexpensive method and apparatus is therefore provided for the continuous manufacture of meshes using various materials. A mesh can be manufactured that has a range of physical and optical properties. The mesh can have good structural strength and a smooth surface appearance. The process can also allow a mesh with small joining elements that is manufactured inexpensively.
Although the present invention has been illustrated by the description of the embodiments thereof, and although the embodiments have been described in detail, it is not the intention of the applicant to restrict or limit the scope of the appended claims in any way.
