Apparatus for stacking flat articles, preferably double bags made of plastic film

摘要

Apparatus for stacking flat articles which in an intermediate portion are formed with locating holes and preferably consist of double bags having opening-defining edges disposed adjacent to their center line. The bags are fed by a wicketer and deposited in a stacking station on an endless stack conveyor and meedled onto raised upstanding stacking pins to form stacks. The stacking pins are operated to be lowered to release the needled stack which then advances to a succeeding severing station provided with a heated knife, which severs the stacks along a center line extending in the direction of stack travel. Additional conveyor belts are provided for retaining the separated stacks on the stack conveyor.
