Abstract: A winding core for winding printed products. The core includes two coil parts, each of which includes at least one coiled profile and a step on each of an inner face and an outer face thereof. The step is formed by a corresponding one of two ends of the at least one coiled profile, each coiled profile further including coil windings having cooperating first joining components disposed on axial sides thereof for joining the windings to one another, each coiled profile having a freely selectable axial extension thereby allowing a free selection of an axial extension of the hollow cylinder. Two end rings of the core include second joining components thereon cooperating with the first joining components for axially joining the two end rings to the coil parts, each inner face of each end ring facing a corresponding coil part including a step thereon juxtaposed against and having an axial extension substantially equal to an axial extension of a corresponding step of the corresponding coil part.

Abstract: A winding core for winding flat articles. The winding core is substantially cylindrical and hollow and thereby defines a longitudinal axis and a cylinder cavity. The winding core is further rotatable about the longitudinal axis, includes a retaining device disposed in the cylinder cavity, and is symmetrical with respect to a plane of symmetry S perpendicular to thee longitudinal axis. The winding core is configured such that its height is adjustable by varying in the axial direction one of a circumferential surface of the winding core and gap heights of gaps defined in the circumferential surface of the winding core.

Abstract: The invention relates to a drive, particularly a push and pull drive, which has a cylinder with a cylinder inner chamber (Z) and a cylinder axis (F) and a piston movably arranged in the cylinder and to which is fixed a flexible force transfer means (U). For a double-action drive the cylinder inner chamber (Z) or the piston must have a larger cross-sectional surface than the force transfer means (U). In order that, despite this, the cylinder wall can serve as a guidance means for the flexible force transfer means, either the cylinder inner chamber or the force transfer means has a non-circular cross-section, so that on a cross-section there are at least two points (A1 to A3), on which the cylinder inner wall can guide the force transfer means.

Abstract: A winding tape for winding up printed products with a fastener having two fastening parts is described, one part of the fastener being the tape-like material and being made from a first polymer of a material pair and the other part of the fastener is an end piece on the tape-like material and at least partly is made from a second polymer of the material pair, the first polymer being chosen from among polyesters, polyamides, polyimides, polyterephthalates and polycarbonates and the second polymer is a hot-melt adhesive based on polyamide-6, polyamide copolymers, polyolefins or polyvinyl alcohol and has at one end a tape-like support material onto which is drawn a hot-melt adhesive film of the second polymer, which is heated for joining together the tape and the tape end and is pressed onto the winding tape.

Abstract: A drive mechanism with a fluid-operable system can be adapted to a general path configuration. The mechanism includes coaxial tubes following a desired path configuration with the inner tube longitudinally slotted in a sealable manner. A fluid-actuated annular piston surrounds the inner tube and operates in the chamber between the inner and outer tubes with a member extending therefrom toward the piston center and extending in the inner tube slot. A flexible force transmission member is provided within the inner tube and extends longitudinally therein, transmitting the motion or force of the piston to a location of use.

Abstract: A universal or ball pivot-link chain is guided in two substantially tubular-shaped guide channels and is deflected or turned between such guide channels by means of a driven chain or sprocket wheel. At its circumference the chain wheel possesses a profiled structure formed by recesses or depressions which substantially correspond to the profile or outer contour of the universal link chain. The guide channels extend to the circumference of the chain wheel and form in conjunction therewith a respective transfer or transition region. At each such transfer region the chain wheel protrudes by an amount, essentially corresponding to the depth of the recesses, into the interior of the related guide channel. At such transfer or transition regions the chain links are guided both by the chain wheel and the guide channels. Consequently, there is ensured for a gentle and jerk-free transfer of the chain links from the chain or sprocket wheel to the guide channels and vice versa.

Abstract: A system removes and conveys a sample copy from a fast moving, orderly material flow of printed materials without disturbing the other products in the material flow. The apparatus includes a power driven conveyor and a conveying chain mounted on guide pulleys, with one of the pulleys located adjacent the material flow. A gripper is coupled to the chain and has a cushioning spring. A cushioning clamp engages and pretensions the cushioning spring to engage a selected sample copy. A control regulates operation of the gripper and clamp in response to detection of individual products and their speed.

Abstract: The transport system comprises a rail and an undercarriage provided with two running wheels arranged in the longitudinal axis of the undercarriage. The running wheels have curved travel or bearing surfaces which rest upon a complementary curved supporting surface of the rail. The undercarriage is guided by a pair of guiding rollers arranged below the rail supporting surface, these guiding rollers engaging a guiding web extending perpendicularly between the guiding rollers. During travelling along curves the undercarriage is inclined towards the interior or inner side, whereby the occurring centrifugal forces are compensated.

Abstract: Within a cylinder of a double-acting piston-and-cylinder unit there is displaceably arranged a piston. A spatially moveable piston rod in the form of a universal or ball pivot-link chain is connected with the piston. The piston rod is lengthwise guided by tensioning or tie bolts internally of the cylinder, these tensioning bolts clamping towards one another both of the cylinder heads and piercingly extending through the cylinder. Externally of the piston-and-cylinder unit the piston rod is guided within a guide tube which is connected with one of the cylinder heads. This guide tube can possess a random spatial extent. At the piston rod there is attached a coupling element with which there can be coupled the object or the like which is to be moved. This coupling element extends through a longitudinal slot provided in the guide tube. The spatial mobility of the piston rod enables guiding the piston rod externally of the piston-and-cylinder unit in a random direction.
