Method and double conveyor for the continuous production of laminated foam sheets

To the continuous manufacture of with covering layers (9, 13) laminated foam webs (26) on a double conveyor belt (1) to avoid the formation of gas bubbles below the upper thick layer (13) is a meshwork web (17) at a distance from 0 to 15 mm from the upper outer layer (13) is introduced, which is preferably made of low-grade material and their adjacent nodes (19) have a distance of 3 to 15 mm from each other while both the maximum height and the maximum width of the webs (18) (wires , threads) of the netting between 0.1 to 2.5 mm.
