Abstract: Two folded and printed products (11, 12) are introduced into a pocket-like holding compartment (1) with respective ones of their side surfaces resting against each other and are moved in such position jointly along a processing section in a direction running transversely with respect to the folded edge. In the course of this movement, the printed products (11, 12) are displaced in opposite directions (H, I) relative to each other in the direction of their folded edge and toward opening elements (7, 8). The opening elements (7, 8) move between the two halves (11a, 11b; 12a, 12b) of the two printed products (11, 12) and have the effect that the two product halves (11a, 11b; 12a, 12b) are lifted off each other. Inserts are then inserted into the printed products (11, 12) opened simultaneously in this way. In a second embodiment, first and second clamping fingers (107, 111) act in conjunction with a pivotable separating element (113) to open the two printed products.

Abstract: A process and apparatus for conveying flexible sheet-like articles 26, wherein the articles are fed to a first curved section 14 by means of a delivery conveyor 10 which includes spaced apart transporting clamps 22 for retaining the articles in a hanging position. Arranged in a radially inward direction at the curved section 14, is a gripper wheel 36 with circumferentially distributed grippers 40 and respective supporting elements 52. The gripper wheel 36 is driven at the same angular velocity as the transporting clamps 22 in the curved section 14. However, a single gripper 40 is assigned in each case to two transporting clamps 22. The lower free edges 32 of the two articles 26 to be joined are guided by a supporting element 52 into a gripper 40, and as soon as this has taken place, the relevant gripper 40 is closed, and the relevant transporting clamps 22 then release the articles 26. The associated supporting element 52 is then drawn back inward in the radial direction.

Abstract: For conveying flat articles (10) in dense conveying streams, grippers (3) conveyed one behind the other by conveying elements (1) are used, each gripper (3) holding one of the articles gripped in an edge zone. For increasing the possibilities for changing the orientation of the flat articles (10) during such conveyance, the grippers (3) are attached to the conveying elements (1) by asymmetrically-projecting gripper arms (2) and the grippers (3) are designed to be rotated through 360° around the gripper arm axis. The device can be used universally, particularly for held conveyance of printed products and it is very easily adjustable for differing applications.

Abstract: The apparatus according to the invention, which serves for transporting supplementary products, in particular sheet-like printed products provided with adhesive, from a receiving location to a discharge location, has at least one retaining element which is moved along a continuous circulatory path and by means of which supplementary products can be gripped at the receiving location and released again at a discharge location. By means of a control arrangement, with changeover operation, during the transportation from the receiving location to the discharge location, the retaining element, which is mounted such that it can be rotated about an axis which is located at least more or less perpendicularly to the circulatory path, is optionally left unchanged in a rotary position or rotated about the axis through a certain angle until an end position of the transported supplementary product which is envisaged for further processing has been reached.

Abstract: A process for combining a plurality of completed printed products such as completed newspapers and/or periodicals, into bundles. At least two storage arrangements are provided, which are occupied by completed printed products of different types. The products are retrieved individually from the storage arrangements in a sequence which is necessary for forming bundles which are composed of a particular distribution of the products. The retrieved products are fed to a receiving conveyor, with certain products being positioned upstream of, or between, products which have already been fed to the receiving conveyor, and the products which follow one after the other in the region of the receiving conveyor are combined into the bundles.

Abstract: The invention relates to a piston pump, having a piston that has a longitudinal bore, that includes a valve seat face upon which a valve closing body is pressed by a valve spring. The valve spring is a helical compression spring, whose winding diameter increases from a winding end that engages the valve closing body to a winding end that rests on a spring seat face formed in the longitudinal bore of the piston. The piston pump of the invention has the advantage that the valve closing body along with the valve spring can be installed in the piston in an axial motion; the valve spring is directly accessible, and a correct seating of the valve and valve spring in the longitudinal bore can be checked visually after installation.

Abstract: This invention relates to a piston pump in a brake system having a piston, which is drivable in a reciprocating motion in a cylinder by an eccentric tang. To avert damage to a ring seal, a support ring is provided which keeps the ring seal spaced apart from a guide sheath for the piston in the cylinder by a distance that is at least as long as a stroke length of the piston. This prevents running scratches on the piston from coming into contact with the ring seal.

Abstract: A reciprocating pump including a piston through which fluid can flow. The piston includes an inlet valve which presses a valve ball against a valve seat in a longitudinal bore in the piston. One end of the piston has a cap-shaped support elements attached thereto against which the inlet valve spring is supported and which engage around an end behind an undercut in the piston.

Abstract: A contact arrangement has a contact spring which is prestressed against a seating edge of an actuation element by a prestress bend. The pre-stress bend lies at an angle of between 0 through 30 degrees relative to the seating edge so that roll-off is produced at the contact location. Such contact arrangement is especially advantageous for switching high-current loads since roll-off at the contact location reduces the welding tendency and makes an easier break-open of the contact when the contact is opening if there is a slight welding of the contacts.
