Abstract
Abstract In a transfer cylinder of a rotary printing press, a combination of a device for correcting registry of a sheet being printed by deforming the leading edge of the sheet, a gripper bridge including three gripper pad bars disposed end-to-end over the length of the bridge, each of the pad bars being individually adjustable in elevation and having a plurality of grippers associated therewith, and an adjusting member carrying the middle gripper pad bar and the grippers associated therewith and being adjustable along the path of feed of the sheet for deforming the leading edge of the sheet, and means effective during operation of the correcting device for closing all of the grippers associated with the middle gripper pad bar and only the outer endmost grippers of the grippers associated with the outer gripper pad bars, and releasing locking pressure of the remaining grippers associated with the outer gripper pad bars and located between the closed outer endmost grippers thereof and the closed grippers associated with the middle gripper pad bar.

Claim 3
Dependent Claim
202 words
Gripper bridge for a transfer cylinder in a multicolor rotary printing press having a device for correcting registry of a sheet being printed by deforming the leading edge of the sheet in the feeding direction of the sheet or in direction opposite or transverse thereto with mechanical control means, the gripper bridge comprising three gripper pad bars disposed end-to-end over the length of the bridge, each of said pad bars being individually adjustable in elevation alternatively parallel and inclined with respect to the axis of the transfer cylinder and having a plurality of grippers associated therewith, and an adjusting member carrying the middle gripper bar and the grippers associated therewith and being adjustable along the feed path of the sheet for deforming the leading edge of the sheet, all of the grippers associated with said middle gripper pad bar and only the outer endmost grippers of the grippers associated with the outer gripper pad bars being closable and the locking pressure of the remaining grippers associated with said outer gripper pad bars and located between the closed outer endmost grippers thereof and the closed grippers associated with said middle gripper pad bar being releasable during operation of the sheet registry correcting device.
