Abstract:
An apparatus for diverting incoming printed products which includes a shaft, at least one first flipper mounted in a first fixed direction on the shaft, a motor coupled to the shaft; and a controller coupled to the motor for controlling positioning of the shaft to allowing printed products to be diverted along different paths associated with a particular shaft position. The apparatus further includes a low inertia coupler interconnected between the motor and the shaft. Alternatively, the apparatus includes a roll, a first motor coupled to the roll and a controller coupled to the first motor for controlling the rotation of the roller for diverting printed products along one of two different paths, each path associated with a direction of rotation of the roll. This alternative apparatus may also include a shaft with at least one flipper mounted thereon and a second motor coupled to the shaft.
Abstract:
A printing press is provided. The printing press includes a print unit printing a plurality of printed products, the plurality of printed products being formed into a stream downstream of the print unit. The printing press also includes at least one base and a press component, the press component is mounted onto the at least one base for placement in the stream and translational movement transverse to the stream. The press component may be a pitch changing apparatus. A method is also provided.
Abstract:
A roll for a web printing press includes a cylindrical member configured for supporting a web, the cylindrical member being rotatable about an axis of rotation. A motor device is disposed at the axis of rotation for rotating the cylindrical member so as to advance the web over the cylindrical member during a webbing-up operation.
Abstract:
The present invention is related to a diverting device for a continuous sequence of flat products travelling in a product travel plane. A first product exit path and a second product exit path emerge both from said product travel plane. An upper set of supply tapes and a lower set of supply tapes each comprise actuatable diverter guide members, respectively. The diverter guide members, form upper and lower diverting planes, respectively, with exit tapes upon movement of the diverter guide members about respective axes.
Abstract:
An apparatus for cutting and folding printed products is provided. The apparatus includes a perforator, a first cutting device creating first slits in the web, a second cutting device creating second slits in the web longitudinally offset from the first slits so as to form a signature with a staggered edge, and a folder delta-folding the signature so that the staggered edge engages slots in the signature, the slots created by the perforator. A method of folding a printed product and a signature are also provided. Lead edges can be more easily prevented from dislodging and dog-earing and skewing can be minimized.

Abstract:
A printing press is provided. The printed press includes a plurality of printing units printing on a web and a folder for processing the web. The folder includes a cutter for cutting the web into printed products and a nip section for reorienting the printed products. The nip section includes a first pair of nip rolls, a second pair of nip rolls and at least one motor driving the first pair of nip rolls and the second pair of nip rolls, the at least one motor driving the first pair of nip rolls at different velocities than the second pair of nip rolls to reorient the printed products. A method for reorienting printed products in printing press is also provided.
Abstract:
A tape transport system for printed products comprising a first tape, a pulley supporting the tape, and a lever arm supporting the pulley, the lever arm including a first side rail and a second side rail, the pulley supported rotatably between the first and second side rails to form a narrow mechanism.
Abstract:
A cylinder in a folding apparatus includes a plurality of product seizing devices. Each product seizing device includes a cam and a shaft having a plurality of product seizing devices attached thereto. A cam follower is mounted to the shaft and a torsion bar is coupled to the cam follower. A torque preloading element for applying a preloaded torque to the torsion bar is provided which maintains the cam follower in contact with the cam. Finally, mechanism for incrementally adjusting and maintaining the preloaded torque on the torsion bar is provided. A variety of mechanisms for incrementally adjusting the preloaded torque are possible. For example, the mechanism may include a first facial toothing on an interior face of the torque preloading element and a second facial toothing on an exterior face of an opposing element. The opposing element is mounted to a work side end of the cylinder and the first facial toothing engages the second facial toothing. The preloaded torque on the torsion bar is incrementally adjusted by relative movement between the first and second facial toothings.
