A machine for folding sheets receives a stream of sheets. A first folding unit is followed by a further unit. The first folding unit has at least one buckle plate and at least two folding rollers to fold the sheets. A monitoring device checks the stream for defects. A control unit activates a removal device for removing waste products when a defect is detected. The monitoring device is disposed at the entry region of the buckle plate and monitors the stream in the buckle plate. The removal device is disposed downstream of the first folding unit and upstream of the further unit. The system, which is suitable for industrial folding machines, reliably detects unusable waste products in the folding process even before production might be affected.

Sheet folding machine with waste product removal

A method for moving a stack of products by a robot. The robot has an articulated arm and at least one gripper disposed on the articulated arm for gripping the stack of products. The stack of products is turned, before being moved by the robot, with a pivoting device that is separate from the robot. The stack of products is turned about a horizontal axis and the stack of products, while out of the horizontal orientation, is aligned and/or straightened in one direction and/or straightened in two mutually orthogonal directions and/or vibrated and/or aerated and/or modified from a fanned-out stack of products to become an unfanned stack of products. The robot then takes the stack from the pivoting device and subsequently moves the stack.

Method of moving a stack of products by use of 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.

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 α< >180° and subsequently pivoting the stack through an effective angle α=180°−αor pivoting the stack back through an effective angle α. 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.

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.

A folding machine for folding sheets of paper, board and the like, includes at least one knife-shaft unit for cutting, perforating, scoring or crimping the sheets. The knife-shaft unit has at least one pair of driven knife shafts. Knife-retaining units for retaining knives are fitted in a rotationally fixed manner on the knife shafts. The knife-retaining units have a split construction and are formed by a plurality of partial shells. A knife holder for a knife shaft of a folding machine, is also provided.
