Реферат: 1,194,311. Packaging. WELDOTRON CORP. 2 Jan., 1969 [24 Jan., 1968], No. 361/69. Heading B8C. A load of articles 12 is located on a pallet 10 by surrounding it by a heat-shrunk film. The loaded pallet is advanced on conveyers through a wrapping station 26 and thence to a shrinking station 28. In the wrapping station it passes into joined sheets of film from supply rolls 30 and guide rollers 32. After the loaded pallet has passed through the wrapping station, the web is closed behind it, cut off and heat sealed by jaws 34. At the shrinking station a manifold 40 is lowered round it spraying hot air from jets 42 to shrink the web. Additional hot air may be supplied below the package and a hood at the top may be used to collect it for recirculation. The manifold may be expansible to accommodate various sizes of load.
