Abstract
Apparatus for stacking and conveying flat articles that are preferably provided with locating holes and preferably consist of bags that have been severed from a tubular or semitubular plastic film web and have been closed by welding. The bags are carried from a forming station to a pair of adjacent, parallel stacking conveyors by a rotatable wicketer having spaced pairs of radial transfer arms. The stacking conveyors include endless belt like carries that pass around rotatable wheels or rollers and are intermittently driven. The carriers include upstanding stacking pins or stacking needles, which extend from and are secured to carrying plates mounted on the carriers. Two spaced, adjacent stacking conveyors are provided and different tools for acting on the intermittently conveyed stacks of bags are selectively provided and detachably secured to the frame of the apparatus between the stacking conveyors. The stacking conveyors and tools are movable transversely relative to the conveying direction to adjust the positions of the tools relative to the bags.
