20140353958 | METHOD OF, AND APPARATUS FOR, PRODUCING MULTI-LEAF, FOLDED PRINTED PRODUCTS, IN PARTICULAR PERIODICALS AND BROCHURES - In a material web which is printed in a digital printing station and moved in an advancement direction, a first material-web strand, which is formed by at least one printed material-web portion, is combined with a second material-web strand, which is formed by two printed material-web portions, by folding. The two material-web strands are connected to one another by an adhesive. Subproducts are then severed from the thus interconnected material-web strands by cross-cutting. These subproducts comprise a first printed sheet, severed from the first material-web strand, and a second printed sheet, connected to the first printed sheet and severed from the second material-web strand. The subproducts are then positioned one upon the other to form a stack, the subproducts being connected to one another by an adhesive in the region of the subsequent folding line. The stacked subproducts are then folded about a folding line to form an end product. | 12-04-2014 |
20140306439 | METHOD FOR PRODUCING PRINTED PRODUCTS CONSISTING OF AT LEAST THREE SUB-PRODUCTS - In a first step, in a printed material web moved in a feed direction, a first material web part formed by a material web section is folded against the rest of the material web that is formed from two material web portions. In the region of a connecting line extending between neighbouring material web sections the two material web parts are connected by a bonding adhesive. In a subsequent step the material web is folded again along a line extending between two neighbouring material web sections. All material web sections lie above one another. Subsequently, multi-page sub-products, the pages of which are connected to one another in the region of the spine of the sub-product, are separated from the twice-folded material web. The sub-products are placed on top of one another to form a stack and connected to one another in the region of the spine by a bonding adhesive. | 10-16-2014 |

20140183808 | METHOD OF, AND APPARATUS FOR, PROCESSING SHEETS OF DIFFERENT FORMATS - A method of processing sheets of different formats, including feeding the sheets of different formats in a feeding direction one behind the other, and at a certain feeding speed, to at least two collecting drums, the at least two collecting drums each having cylindrical lateral surfaces, driving each of the at least two collecting drums about a respective axis of rotation at a circumferential speed, the circumferential speed corresponding to the feeding speed of the sheets, temporarily securing at least some of the sheets on one of the at least two collecting drums to form a sheet stack, detaching the sheet stack from the at least one of the at least two collecting drums, and bringing together the sheets or the sheet stack detached from the at least one of the at least two collecting drums with sheets or a sheet stack detached from another one. | 07-03-2014 |
20130036884 | METHOD AND APPARATUS FOR PUNCHING OR PERFORATING MOVING MATERIAL WEBS - In order to make holes with different spacings between them, a punching tool is provided with punching dies on its circumference and interacts with an impression cylinder. Between two punching operations, either of the punching dies and the impression cylinder is driven, at times, at a circumferential speed that is greater or smaller than the movement speed of the material web that is to be punched or is stopped briefly and, until the next punching operation, brought once again to a circumferential speed that corresponds to the movement speed of the material web that is to be punched. | 02-14-2013 |
20120242027 | METHOD OF, AND APPARATUS FOR, PROCESSING SHEETS OF DIFFERENT FORMATS - Sheets of different formats, i.e. of different format lengths, are transported in a feeding direction one behind the other; and at a certain conveying speed, to at least two collecting drums, which have essentially cylindrical lateral surfaces. Each of these collecting drums is driven about an axis of rotation at a circumferential speed, which corresponds essentially to the feeding speed of the sheets. The first incoming sheet is secured temporarily on one of the collecting drums, while the following, second sheet is secured temporarily on the other collecting drum. At a suitable point in time, the two sheets secured on the collecting drums are detached from the collecting drums and brought together with the third fed sheet to form a sub-product or end product. | 09-27-2012 |
20120204692 | APPARATUS FOR PUNCHING MOVING MATERIAL WEBS - In order to punch a moving material web there are two punching units present, which are arranged one after another in the direction of movement of the material web. Each punching unit has two punching tools, which interact with a rotatably mounted back-pressure cylinder that can be driven. The punching tools are arranged on a rotatably mounted drive shaft that can be driven, and their position can be adjusted in the direction of the longitudinal axis of the latter and locked in various working positions. Each punching tool has a cylindrical base, to the periphery of which a punching strip which is provided with at least one punching shape is fixed such that it can be replaced. The drive shafts can be driven independently of the associated back-pressure cylinder. | 08-16-2012 |
20110281707 | Apparatus for longitudinally folding a moving material web twice - In order to form two longitudinal folds in a material web, there are two plow folding units which extend in the vertical direction and are arranged behind one another in the movement direction of the material web. Each of the plow folding units has two guide elements for the material web, which guide elements are arranged in the manner of a gable or saddle roof. The guide elements are arranged behind one another in the movement direction of the material web and enclose a folding angle between them. The folding angle between the guide elements of the second plow folding unit which is arranged downstream of the first plow folding unit has a magnitude of at least 100°, preferably of at least 140°. | 11-17-2011 |
20110277608 | Apparatus for the cross-perforation or cross-cutting of continuous material webs - In a cylindrical knife holder rotatable about its longitudinal axis, at least one groove, which is open towards the peripheral surface thereof, is present. The groove extends in the direction of the longitudinal axis of the knife holder. Inserted exchangeably in this groove is a perforating knife, the perforating edge of which protrudes over the peripheral surface of the knife holder. The perforating knife, which can be clamped in the groove by means of a releasable clamping device, is supported, at its end lying opposite the perforating edge, on a stop element disposed in the groove. The stop element rests on supporting elements distributed over the length of the groove, which are adjustable in directions running transversely to the longitudinal extent of the groove. The supporting elements define the once set radial position of the perforating knife. | 11-17-2011 |
20100051196 | Method and apparatus for producing stacks which form book blocks - In order to form stacks, of which each forms a book block, folded sheets are provided with an adhesive application or layer of adhesive before they are placed on one another. Said adhesive application is applied to the sheets adjacent to the folded edge of said sheets and extends in the direction of said folded edge which comes to lie in the spine of the book block. The adhesive can be applied as a continuous track or as a track which is interrupted multiple times, or else in a punctiform manner. The sheets are joined to one another in the stack by means of said adhesive application, with the result that they maintain their position within the stack during further transport of the stack. | 03-04-2010 |

The two material-web strands are connected to one another by an adhesive. Subproducts are then severed from the thus interconnected material-web strands by cross-cutting. These subproducts comprise a first printed sheet, severed from the first material-web strand, and a second printed sheet, connected to the first printed sheet and severed from the second material-web strand. The subproducts are then positioned one upon the other to form a stack, the subproducts being connected to one another by an adhesive in the region of the subsequent folding line. The stacked subproducts are then folded about a folding line to form an end product. | 01-21-2010 |
