For producing stacks ( ), flat objects ( ) are supplied individually held by holding elements ( ) in an edge zone ( ). Groups ( ) of the objects ( ) are supplied one behind the other and arranged in a stack by placing object zones opposite the held edges ( ) adjacent to one another. While the objects ( ) are held, the groups arranged in a stack are stabilized by positioning the object zones opposite the held edges ( ) on a stacking table ( ) that is vertically movable inside a stacking shaft ( ) and/or on an auxiliary support ( ), and are either strapped or pressed together by a pressing device. Prior to being deposited on a stacking table ( ), groups ( ) formed one behind the other and arranged in a stack may be rotated around the stacking axis (A), so that they are positioned in the stacking shaft ( ) as layers of a cross stack.

Method and device for stacking flat objects

An apparatus for reducing a stack of flat, flexible articles, in particular printed products, having bearing elements which are moved along a continuous circulatory path U and, in a first sub-section A of the circulatory path U, U , U , form a stack rest . The apparatus has at least one separating element which is capable of raising off a region of the lowermost article located in the stack such that at least one of the bearing elements can move in between the lowermost article and the rest of the stack and can separate off the lowermost article from the rest of the stack as it moves further. The apparatus further comprises a belt conveyor which is arranged beneath the stack rest and on which the articles come to rest once they have been separated off. The bearing elements can be pivoted or displaced such that it is possible to change their position relative to the circulatory path U, U , U , to thereby allow the belt conveyor to extend forwardly without interference with the bearing elements.

Apparatus for reducing a stack of flat, flexible articles

To a row of winding stations ( ), in which rolls ( ) of flat, bendable objects (e.g., printed products) positioned on roll supports ( ) are processed or in which such rolls are produced, roll supports ( ) are coupled to the winding stations and, if required, are exchanged, the coupled roll supports forming a first row (A) of roll supports parallel to the row of winding stations ( ). Roll supports ( ) are positioned in readiness for the exchange in a second row (B) of roll supports, which second row (B) is distances from the first row (A) by a transport alley ( ). Each roll support in the second row is aligned to the one winding station ( ), to which it is to be coupled. For every exchange, the roll support ( ) coupled to the winding station ( ) is moved transverse to the first row (A) into the transport alley ( ) and is transported along the transport alley to its end and there is positioned in a third row (C) of roll supports, which is aligned in the direction of the transport alley ( ) and adjoins it.

Method and installation for exchanging roll supports on winding stations arranged in a row

A method for dismantling a stack ( ) of flat objects ( ) piece by piece, in which the top object ( ) of the stack ( ) is moved in its plane, gripped at its freed edge and removed from the stack ( ). The top object ( ) is moved against a stop ( ), at least in the region of one of its corners ( ), by a movable separating element ( &prime;) and, as a result of further movement, is bent in such a way that it escapes from the stop ( ) and is moved out of the stack ( ). The invention further relates to an apparatus for dismantling a stack ( ) of flat objects ( ) piece by piece.

Method and apparatus for dismantling a stack of flat objects piece by piece

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

Process and apparatus for combining sheet-like articles and jointly transporting them further

For conveying flat articles ( ) in dense conveying streams, grippers ( ) conveyed one behind the other by conveying elements ( ) are used, each gripper ( ) holding one of the articles gripped in an edge zone. For increasing the possibilities for changing the orientation of the flat articles ( ) during such conveyance, the grippers ( ) are attached to the conveying elements ( ) by asymmetrically-projecting gripper arms ( ) and the grippers ( ) are designed to be rotated through &deg; 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.

Device for held conveyance of flat articles in a dense conveying stream

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.

Apparatus and process for transporting supplementary products

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.
