<p><P>PROBLEM TO BE SOLVED: To form a stack at high speed while feeding sheets at low speed to prevent curls and tip damage of the sheets. <P>SOLUTION: Sheets 8 entering to a zone 310 at predetermined speed one by one are sequentially sent to a next zone 320. The zone 320 receives sheets shorter than the length of the zone 320. Inside the zone 320, pinch nips 320A-320E for carrying sheets 4-7 at low speed are arranged, and the sheets are sequentially shingled with each other and are continuously sent out. In a next zone 340, a plurality of suction feeding sub-assemblies 340A-340E for carrying tip sides of sheets 1-3 by vacuum suction, respectively are arranged at intervals less than or equal to the length of a shift between sheets in the process direction. While shingled, the sheets are carried and sent out from the final stage sub-assembly 340E to a zone 350 one by one. In the zone 340 as a whole, a plurality of sheets can be carried simultaneously. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
