摘要
Welded carrier bags (5) are placed on top of and behind each other and transported as a scale-like assembly. An automatic signal is produced and a gap formed in the continuous flow to create groups of bags which are then folded, preferably in a Z-form, and fed to a removal conveyer (21) acting as a buffer zone. An Independent claim is made for the process plant in which an initial stacking unit has an intermittently moving suction conveyer at least twice the width of the bags (5), a scale flow forming conveyer with belt (6) controlled by a measuring system, bag group forming mechanism and a bag removal conveyer (21). The suction conveyer belts (2) are toothed belts and have a section similar in width to a bag extending transversely into the scale flow conveyer. The measuring system controls periodic brief and high speed movement of the endless conveyer belt (6) to form bag groups within the continuous scale-like flow and a toothed belt above has a finger which inserts into gaps formed between bag groups. The removal conveyer has a continuously driven conveyer belt (43) parallel to and offset from the scale flow conveyer. A transverse transporting system between the parallel conveyer belts has pneumatically operated grippers and a bag group folding mechanism is located in this area.
