The upper guide unit is configured such that a gap between the upper guide unit and the lower guide unit widens in accordance with a thickness of the booklet to allow the booklet to pass through the gap.

FOLDING ROLLER COMPRISING COATING

A folding roller for folding signatures in a folding apparatus comprises a cylindrical folding rolling element comprising a jacket surface at least partially having an elastic coating that is compressible. As such, different folded products and/or folded products of different thicknesses can be produced without a change of the nip between the folding roller pair with consistent folding quality, and an adjustment of the nip is also not required during a production run printing or an ongoing production.

DEVICE FOR MOVING A STACK OF PRODUCTS USING A ROBOT

A device for moving a stack of products using a robot. The robot has an articulated arm and a first gripper for the stack of products. The first gripper is disposed on the articulated arm. A gripping device is disposed on the articulated arm, the gripping device contains the first gripper and a second gripper, the first and second grippers are positionable relative to one another. Robot advantageously provides a method of moving stacks of products in an automated way and in particular of depositing them in a turned or unturned arrangement.

METHOD OF MOVING A STACK OF PRODUCTS BY USE OF A ROBOT

A method moves a stack of products by a robot. The robot has an articulated arm and at least one gripper disposed on the articulated arm to grip the stack of printed products and the stack of products selectively being turned. The method includes pivoting the stack of products through an effective angle α1< >180° and subsequently pivoting the stack through an effective angle α2=180°−α1 or pivoting the stack back through an effective angle α2=−α1. This method of moving stacks of products is performed in an automated way and in particular of depositing them in a turned or unturned arrangement.

METHOD OF MOVING A STACK OF PRODUCTS USING A ROBOT

A stack of products is moved with a robot which has an articulated arm and at least one gripper disposed on the articulated arm to grip the stack of products. The stack of products can be selectively turned. The step of moving terminates at a selected deposit location of a number of deposit positions of a predefined deposit scheme. The stacks of products are moved in an automated way and, in particular, the stacks are deposited in a turned or unturned arrangement.

METHOD OF MOVING A STACK OF PRODUCTS USING A ROBOT

A stack of products is moved using a robot. The robot has an articulated arm and grippers on the articulated arm to grip the stack of products. The stack of products is selectively turned in the depositing scheme. Two grippers are used in the method and, upon the deposit, the grippers are removed from the stack of products in the horizontal and in two directions perpendicular to one another. It is possible to move and selectively deposit stacks of product in a turned or unturned orientation.

The upper guide unit is configured such that a gap between the upper guide unit and the lower guide unit widens in accordance with a thickness of the booklet to allow the booklet to pass through the gap.

Apparatus and method for the optional cross-folding of sequentially printed sheets or signatures
11034542 · 2021-06-15 · ·

An apparatus and method for optional cross-folding of successively following, sequentially printed sheets on a first transport segment. A compressed air device comprises a first control element that is connected to a control unit for triggering or suppressing a compressed air blast from at least one exit opening in the compressed air device. A printed sheet is diverted into a second transport segment for the folding operation or a third transport segment for bypassing the folding operation. The latter empties downstream of folding rolls into the second transport segment at a joint segment point, at which a fourth transport segment adjoins in downstream direction. The third transport segment is longer than the second transport segment or can be operated at a lower speed than the second transport segment such that a first sequence of printed sheets successively following on the first transport segment is identical to a second sequence of the successively following printed sheets located on the fourth transport segment.
