method and device for the manufacture of a flächenförmigen component

摘要

Inflatable panels are made by leading a continuous flexible plastic tube around a conveyor belt stretched between twin driven pulleys. After the tube has followed one complete circuit of the belt the superimposing surface is treated with =1 stripes of adhesive, symmetrically or assymmetrically disposed. The loop of superimposed coils is severed normal to the conveyor to obtain =1 panel. Ancillary rods may be accommodated within the tubing or in the interfacial space between parallel welds. Esp. for mfr. of panels of assymetrically linked longitudinal chambers which can be inflated to form a self-supporting shelter. Requires less manipulation than assembly of panels from several independent prefabricated lengths of tubing.
