Abstract
A sheet handling apparatus includes first and second endless belts (38, 40) which are of resiliently stretchable material and parts of which are in cooperative relationship with respect to each other, a sheet (68) being fed through the apparatus while gripped between the cooperating parts of the belt drives (38, 40). One of the belt drives (40) passes around a pulley (60) associated with selectively operable actuating members (42, 46, 50, 52, 54). Operation of the actuating members (42, 46, 50, 52, 54) moves the associated pulley (60) so as to bring out a deformation of the cooperating parts of the belt drives (38, 40) and thereby change the length of the feed path for the sheet (68) through the apparatus. By operating the actuating members (42, 46, 50, 52, 54), the time at which the sheet (68) arrives at a certain location, such as a stacking wheel 75, may be adjusted. By using two pairs of cooperating belt drives of this type, the orientation of a sheet passing between the cooperating belt drives may be adjusted.
