ABSTRACT:
Apparatus for cutting a continuous web into precise length sheets and precisely stacking the sheets, relative to each other, includes first and second moving endless belt tables for advancing the web, a sheet orientation table and a stacking table. A vacuum holds the web firmly, without tension, against the respective belts. A shearing device is disposed between the first and second endless belts. Web, detectors positioned along the line of travel of the web, detect printed or colored lines on the web to obtain accurately cut sheets. Individually driven and positioned sheet grippers grasp the cut sheet positioning each sheet under dual hole punching devices which punch precisely positioned holes in each sheet. A pair of aligning pins on a sheet stacking bed are used as guides for orienting the sheets in interleave configuration. Each sheet is secured to its adjacent sheet to maintain sheet orientation.
