ABSTRACT:
Sheet feeding device and method for feeding sheets of two different regular lengths, comprising a sheet length detector for automatically sensing the length of the next sheet in the sheet-supply station of the device, prior to movement of said sheet and conveying this information to the logic system which controls the operation of the machine. The detector is attached to the machine for automatic movement into the sheet-supply station, which is normal operating position, and for automatic withdrawal out of the sheet-supply station to provide easy access to the sheet-supply station for the insertion of new sheet stacks and to prevent damage to the sensitive detector during the insertion of such sheet stacks.
