Abstract
Apparatus for processing flat strip material including cutting apparatus for cutting the material and to strip portions and stacking apparatus having air cushion means for stacking the strip portions one on top of the other. An accelerating anchoring roller, having vacuum or magnet devices therein for attracting the sheet portions thereto are provided for the exclusive transfer of the strip portions from the position were cut in the cutting apparatus in positions at the inlet of the stacking apparatus where the air cushion takes over the conveyance and stacking of the strip portions.
Claims16
Apparatus for processing strip material comprising:
- cutting apparatus for cutting strip material into strip portions,
- stacking apparatus disposed downstream of said cutting apparatus and including means for stacking said strip portions adjacent one another, said stacking apparatus including air supply means for supplying air to respective undersides of said portions to form a cushion of air for said strip portions as they are stacked,
- and an accelerating anchoring roller member engageable with said strip portions for acceleratingly conveying strip portions from the cutting apparatus to respective positions adjacent an inlet portion of said stacking apparatus where they are engaged by said air from said air supply means, said anchoring roller means forms the exclusive means for transferring said strip portions from respective positions where they are cut to respective positions at said inlet portion of said stacking apparatus where they are engaged by and controlled by said air from said air supply means, said anchoring roller member includings anchoring means for aiding in anchoring said strip portions for movement with peripheral portions of said anchoring roller member,
- said anchoring roller member is disposed in a frame of the stacking apparatus above an air outlet of said air supply means, and control means for controlling an anchoring effect of the anchoring means as a function of the cutting process in the cutting process.
