Abstract
Apparatus for the selectably alternative feeding of single sheets and of endless webs of paper in a printer includes a guide roll (7), and first and second groups (8, 9) of friction rollers concurrently movable between first and second positions to define respective single sheet and endless web feeding modes of operation. In their first positions, the first friction rollers (8) contact the guide roll (7) to define a first single sheet feed channel (4) and the second friction rollers (9) contact the guide roll (7) to define a second single sheet feed channel (5). When shifted to their second positions, the first friction rollers (8) are displaced from their first position contact with the guide roll (7) to substantially eliminate the first single sheet feed channel (4), and the second friction roller (9) are lowered to form with the guide roll (7) an endless web feed channel (6).
