A folding jaw arrangement ( ) at a lateral surface ( ) of a product-carrying cylinder ( ) in folding apparatuses. The folding jaw arrangement ( ) includes a stationary folding jaw part ( ) and a movable folding jaw part ( ). Formed therebetween is a gap ( ) into which a folding means ( ) of further cylinder ( ) co-operating with the product-carrying cylinder ( ) plunges during the cross-folding of products. In the process, the product to be cross-folded passes from the further cylinder ( ) to the lateral surface ( ) of the product-carrying cylinder ( ) and is held thereon by the folding jaws ( ). The movable folding jaw part ( ) is provided with resilient regions ( ) via which the product is brought into and held in contact ( ) with the stationary folding jaw part ( ) of the folding jaw arrangement ( ).

A rotary-blade folding unit includes at least one folding blade, a pair of folding rollers and a drive for producing a hypocycloid movement of the folding blade about a rotational axis of the folding blade and a main rotational axis for folding a signature that has been guided up to the rotary-blade folding unit in a transport plane extending between the main rotational axis and the folding rollers, and further includes a drive mechanism for producing an oscillatory movement of the folding blade at least approximately parallel to the main rotational axis; a folder including the folding unit; and a printing machine in combination with the folder.

Rotary-blade folding unit

The present invention relates to a copy-carrying cylinder which has a peripheral surface ( ) supporting sheet-like copies and which is provided with retaining elements for fixing the sheet-like copies in place on the peripheral surface ( ). A folding device ( ) which can be moved into and out of openings ( ) at the peripheral surface ( ) are bounded by at least one movable surface element ( ). The surface element ( ) which is associated with the folding device ( ) is designed in such a manner that it takes its closed position ( ) automatically.

A paddle wheel delivery for flat copies, which are delivered onto a belt surface of a delivery belt, the paddle wheel delivery including at least one paddle wheel formed of two paddle wheel disks mutually adjustable relative to one another. The delivery includes sickle-shaped regions inwardly movable by a relative movement of the paddle wheel disks, for converting a first pocket width of the paddle wheel pockets on the paddle wheels into a second pocket width of the paddle wheel pockets. Also included is a folder including the paddle wheel delivery; and a web-fed rotary printing machine including the paddle wheel delivery.

A device for cross cutting material webs includes a cutting-cylinder pair formed of mutually cooperating cylinders having respective cylinder cores and circumferential surfaces formed by exchangeable circumferential elements, the circumferential elements being arranged removably around the respective cylinder cores of the cylinders.

Device for cross cutting material webs

In a device for cutting a web of material in a folder having a cutting tool accommodated on a cutting cylinder, there is provided a cutting tool support which includes pressure bars of elastic material flanking and directly engaging the cutting tool, and projecting resiliently beyond a jacket of the cutting cylinder, the pressure bars being formed of an elastic base material and a contact material having a greater hardness than that of the base material, the base material of the pressure bars being in engagement with the web of material during the cutting of the web of material.

Device for delivering printed products from a fan arrangement for forming a shingled printed-product stream, the device including an endless chain having a revolving path coordinated with the fan arrangement, so that the chain continually pushes, out of pockets of the fan arrangement, printed products received in the pockets, for forming the shingled printed-product stream, further including a holding arrangement for holding the printed products in the pockets, the holding arrangement being formed of grippers disposed on the chain.

Device for delivering printed products from a fan arrangement

A folding device is provided which produces folded printed products from an incoming web of printed material. The folding device has a mechanism for automatically converting the folding device from a configuration that forms a single transverse fold to a configuration that forms a second transverse fold parallel to the first fold. The conversion mechanism has a set of movable belts wound partially around a first folding cylinder and partially around a second folding cylinder. It also has a device for moving the set of movable belts to a first position, where the set of movable belts is wound partially around the first folding cylinder downstream of a plane P passing through the axes of the first and second folding cylinders, for forming a single transverse fold and to a second position, where the set of movable belts is wound only partially around the second folding cylinder downstream of the plane P passing through the axes of the first and second folding cylinders, for forming a second transverse fold parallel to the first fold.
