ABSTRACT:
An apparatus for cutting, sorting and stacking paper or the like in sheet form is disclosed which includes means for collecting packets of sheets in tandem on a collecting drum prior to discharging the collected sheets to the stacker. The basic components consist of a sheet cutting section, a sheet collecting section, a sheet slow down section and a stacker unit. In the tandem collect mode of operation, the length of the cut sheets must be less than one-half the circumference of the collecting drum and the drive ratio between the sheet cutting section and the sheet collecting section is set at 2:1. Packets of sheets containing an odd number of sheets are collected in tandem on the collecting drum with the use of air showers that are controlled by microswitches in an air shower control unit that is driven by the cutting drum. The drive ratio between the cutting drum and the air shower control unit and the number of microswitches in the air shower control unit determine the number of sheets collected in each packet.
