A system for the replacement of sleeves that can be slipped on arbors of ink transfer rollers of at least printing machine has a storage device, in which the sleeves not being used in current ink transfer can be stored, and a transport device, with which several sleeves can be transported to the printing machine. The system has a transfer device the facilitates the transfer of the sleeves between the storage device and/or the transport device and the arbors of the ink transfer rollers, and/or between the storage device and the transport device.

A system for the replacement of sleeves that can be slipped on arbors of ink transfer rollers of at least printing machine has a storage device, in which the sleeves not being, used in current ink transfer can be stored, and a transport device, with which several sleeves can be transported to the printing machine. The system has a transfer device the facilitates the transfer of the sleeves between the storage device and/or the transport device and the arbors of the ink transfer rollers, and/or between the storage device and the transport device.

A system for replacement of sleeves that can be slipped on arbors of Wei y transfer rollers of a printing machine has a storage device, in which the sleeves, which are not used in cl current ink transfer, can be stored, and transport devices, with which several sleeves can be transported to the printing machine, Devices for the transfer of the sleeves with which the sleeves can be transported between the storage device, the transport devices, an, the arbors of the ink transfer rollers include devices for receiving the sleeves, which are associated with a robotic arm such that the devices for receiving the sleeves have three degrees of freedom for translation and are rotatable about at least two axes of rotation.

A changing station for sleeves of a printing machine has a conveyable magazine with at least one take-up device for the sleeves. The magazine is both vertically and horizontally conveyable alongside the printing machine. The horizontal movement can be provided by a rail, and the vertical movement can be provided by a crane or hoist.

A cutting and transport roller and a process for cutting the material webs which rest on the peripheral surface of the cutting and transport roller. In so doing, the material webs are severed with the aid of a cutter, which is located inside the shell of the cutting and transport roller in its resting position and which exhibits at least one knife, which during the cutting process of the material web reaches through an opening in the shell of the cutting and transport roller. The cutting motion, which is executed by the cutting surfaces of the knife during the cutting process, exhibits rotary components, whereby the rotational motions of the knife run about an axis of rotation, which is either parallel or at an acute angle to a perpendicular line on the plane which is defined by the radial (r) and axial (z) coordinates of the cutting and transport roller.

A lay-flat removal device for a plastic tube film web with a lay-flat and squeezing device having lay-flat plates and squeezing rolls that are rotatable in a reversing manner around an axis of a supplied film tube. The removal device includes a first reversing, non-rotational pneumatic reversal rod and a first reversing, rotating deflection roll mechanically connected to one another in a first fixed transmission ratio to form a first functional pair which is driven by a first motor, and a second reversing, non-rotational pneumatic reversal rod and a second reversing, rotating deflection roll mechanically connected to one another in a second fixed transmission ratio to form a second functional pair driven by a second motor. The motors are controlled in such a way that the different functional pairs cover angles of rotation that can be determined in a variable manner.
