    A machine for automatically packaging lugs and the like comprising means forming a guide channel for receiving a row of upright lugs in an aligned oriented row, drive means on opposite sides of the channel and extending thereinto for engagement with a row of juxtaposed lugs in the channel to advance the row along the channel, means for feeding a pair of flexible pressure sensitive adhesive strips to opposite sides of a row of lugs in the channel, a pair of rotatable pressure members disposed on opposite sides of the channel resiliently engageable with the adhesive strips on opposite sides of the lugs to . press the strips into firm engagement with the lugs as υ the lugs are advanced between the pressure members by said driving means to provide a self-supporting row of lugs, and take-up means for coiling said self-supporting row of lugs.
  3. 3
    A machine for automatically packaging lugs and 45 the like comprising a pair of guide rails forming a guide channel for receiving a row of lugs in an aligned oriented row, drive means for advancing a juxtaposed row of lugs along the channel, a pair of turntables on opposite sides of the guide channel, each adapted to support a coil of pres50 sure sensitive adhesive tape, means for feeding the tape from the coils to opposite sides of a row of lugs in the channel including a pair of apertures in the guide rails and a roller mounted in each aperture, a pair of rotatable pressure members disposed on opposite sides of the chan65 nel and each having a resilient peripheral portion respectively engageable with adhesive tapes on opposite sides of the lugs to press the tapes into firm engagement with the lugs as the lugs are advanced between said pressure members to provide a self-supporting row of lugs, and θθ take up means adjacent the exit end of said guide channel for coiling said self-supporting row of lugs with the row under tension including a turntable and means to drive the turntable including a yieldable clutch.
  4. 4
    A machine for automatically packaging lugs and the 65 like comprising means forming a guide channel for a row of lugs, drive means engageable with lugs in said channel to advance a juxtaposed row of lugs along the guide channel, means to apply automatically a pair of elongated pressure sensitive adhesive strips to opposite sides of the 70 row of lugs during the advance thereof along said channel to provide a self-supporting row of lugs, means adjacent the exit end of said guide channel to coil the self-supporting row of lugs with the row under tension, and means to engage a flexible elongated spacer member between 75 next adjacent courses of lugs as said self-supporting row is 3 gear connection between the drive wheels will result in rotation of the wheel 24 in a clockwise direction, and the wheels will advance lugs in the channel 21 leftwardly, between the rubber wheels 36, 38. As the row of lugs is passed between the rubber wheels, the tapes 10, 11
  5. 5
    5 will be picked up by the lugs and pressed into firm engagement with opposite sides of the row to provide a self-supporting row of lugs. The assembled row of lugs then passes from the leftward exit end of the guide channel onto a plate 54, supported above the table 18. The 73 pressure of the rubber wheels on the lugs necessary to firmly adhere the tape thereto provides sufficient resistance to passage of the lugs between the rubber wheels to cause a slipping of the shaft of the drive wheel 22. This slipping of the drive wheel shaft assures that the lugs between the drive wheel and pressure wheels will be tightly compacted when the tape is applied thereto even though, as will be later seen, an additional force is applied to the taped row of lugs generally in the direction of movement of the row by the drive wheels. The taped row of lugs is then led onto a turntable 56 which, as will be seen, is also driven by the chain 32 so as to coil the self-supporting strip or row of lugs. With reference to Fig. 4, the turntable 56 comprises a shaft 58 journaled on a pedestal 60 mounted on the base 17. A sprocket 62 is mounted for rotation with the shaft 58 and is engageable with the chain 32. Keyed to the shaft 58 is a base member 64 which supports a friction member 66, the other side of which engages and supports a turntable plate 67 adapted to support the coil support base member 13. Fixed to the turntable plate 67 for rotation therewith is a sleeve 70 disposed coaxially of the shaft 58 and on which is threadably mounted a cap 72. A nut is threadably mounted on the upper end of the shaft 58 and engages a washer 74 which engages one end of coil spring 76 disposed about the shaft 58. The other end of the spring is engaged with the inner race of a bearing 78 mounted on the shaft 58. The outer race of the bearing is fixed for rotation with the sleeve 70. As should be apparent, there is thus provided a slip clutch between the shaft 58 and turntable plate 67 with the force which will cause slipping of the clutch being determined by adjustment of the spring 76. Also mounted on the sleeve 70 is a collar 80 of suitable resiliently compressible material such as rubber. A spacer 82 is disposed between the collar 80 and a cap 72 whereby threading of the cap toward the collar 80 will axially compress the collar causing it to expand radially outwardly of the turntable into firm engagement with the tubular center member 14, thus forming a driving connection between the turntable and coil supporting member. A similar arrangement for mounting the coils of pressure sensitive tape on the turntables 48 and 50 is provided. As can be seen in Fig. 3, the turntable 48 is fixed for rotation with a rotatable sleeve 85 supported on the outer race of a bearing, the inner race of which is mounted on a stub shaft supported on the table 18. Threadably mounted on the sleeve 85 is a cap 86, and as can be seen in Fig. 3, threading of the cap 86 axially inwardly of the sleeve 85 will move an annular spacer 87 mounted externally of the sleeve 85 into engagement with a collar 88, also mounted on the sleeve 85. The collar, which is of compressible material such as rubber will accordingly be expanded radially outwardly of the sleeve 85 into engagement with the roll of tape 47 to retain the tape on the turntable. A pair of tubes 92, 94, as can be seen in Figs. 1 and 5, are pivotally mounted on a pedestal 96 supported on the base 17. The tubes are spring biased radially inwardly of the turntable 56 and as most clearly seen in Fig. 5 are adapted to receive and guide the pair of spacer members 15, 16 into engagement with the outer 2,898,718 being coiled with said spacer member engaging next adjacent adhesive strips. _ 5. A machine for automatically packaging lugs and the like comprising means forming a guide channel for a row of lugs, drive means engageable with lugs in said channel to advance a juxtaposed row of lugs along the guide channel, means to apply automatically an elongated pressure sensitive adhesive strip to each side of the row of lugs during the advance thereof along said channel to provide a self-supporting row of lugs, means to coil the self-supporting row of lugs under tension including a turntable for the support of the lugs and means to drive the turntable including an adjustable yieldable clutch, and means to engage a flexible elongated spacer member between next adjacent courses of lugs as said self-supporting row is being coiled with said spacer member engaging next adjacent adhesive strips.
