<p>Sheet material from a mechanism (2,4) is delivered successively in substantially the same plane to form a stack (10,12) with the sheets thereof ordered in the same sequence as their delivery, the sheets being passed along a path (100) to a receiving tray or track (14) and the speed of such passage reduced in at least one stage (96,98) in the path to cause successive sheets to overlap prior to receipt in the tray where the stack is completed. Reducing stages (96,98) can be located at the inlet to and/or in the path (100), and may comprise roller devices (96,98,116) arranged successively in the path with means (108) for driving the downstream device (98) at a speed lower than that of the upstream device (96). In another aspect the invention contemplates the simultaneous formation of adjacent stacks (10,12) in which sheets are delivered in substantially parallel streams and then passed along divergent paths to receiving means. In at least one of the paths a skew roller device (96,98,116) is disposed to laterally deflect sheets as they pass therethrough to determine such divergence. <IMAGE></p> |
