Title:
【発明の名称】用紙回転機構
Document Type and Number:
Japanese Patent JP2941851
Kind Code:
B2
Abstract:
A copy sheet rotator in which a sheet is moved by two separately driven crowned rolls that form nips with cooperating idler rolls. For sheet turning, one roll is stopped with the sheet in the nip while the other roll continues to drive and rotate the sheet. A separate scuffer roller registers the rotated sheet after it has been released from the rolls without scuffing damage. The position, angle and velocity of the scuffer allows the sheet to remain in tension during rotation and therefore prevents buckling without the need for nip release systems.
