摘要:
The invention relates to an apparatus for decelerating sheets (9), especially paper or cardboard sheets, which are to be placed on a stack (6). Said apparatus comprises rotatably driven clamping elements (16) which are disposed across the width of the apparatus on at least one side of the conveying plane of the sheets (9) and are provided with clamping zones (17) that intermittently reach all the way to the feeding plane of the sheet (9) when revolving. The inventive apparatus further comprises a mating element (18) which is rotationally disposed on the opposite side of the conveying plane of the sheets (9) such that a sheet can be clamped between the clamping zones (17) and the mating element (18). The clamping elements (16) are connected to an asymmetrical rotary drive unit while being equipped with ring segment-shaped clamping zones (17) on a section of the circumference thereof. Furthermore, a deflecting device (13) which deflects the rear edges of the sheet from the feeding plane in a downward direction is arranged at a distance from and upstream of the clamping elements (16) in the direction of travel of the sheets.

A method and apparatus are for decelerating a sheet of paper in a paper-cutting system. The sheet of paper is cut (705) using a cutter, and the sheet is then accepted (710) into a take-away nip. The take-away nip is operated (715) at an initial rate in order to move the sheet of paper away from the cutter at an initial speed. The take-away nip is then operated (735) at a rate decreasing to a final rate, in order to decelerate the sheet of paper to a final speed by the time the sheet of paper exits the take-away nip. The take-away nip is subsequently operated at the initial rate again, prior to accepting another sheet of paper at the initial speed.

A folder (10) operable to cut a printed web received from a printing press. The folder includes a cutting section (30) having cutting cylinders (34) that cut the web into individual printed products, and a cutting motor (M2) that is operable to drive the cutting cylinders (34). A delivery assembly of the folder includes delivery belts (38;42) that are operable to guide the individual printed products through the folder, and at least one delivery motor (M3;M4) is operable to drive the delivery belts (38,42). The folder also includes a diverting assembly (66) that diverts individual printed products to one of a plurality of collation paths, and a diverting motor (M5) that is operable to drive the diverting assembly (66). The cutting motor (M2), the delivery motor (M3;M4), and the diverting (M5) motor are operable independently of one another.

The invention relates to a device for cutting off and conveying streaks, for a machine. The device is used for producing a continuous web, especially of paper or card, for a threading streak, and has a knife. Finally, the device is characterized in that it has at least one (preferably driven) guiding roll (27) which can be brought into engagement with the threading streak (27).

Dough pieces are produced in high volume by a plurality of dual extruders spaced across a conveyor and each having a pair of extrusion nozzles aligned in the direction of conveyor travel. A cut-off mechanism severs the dough extrusions to deposit dough pieces on the conveyor. The speed of the conveyor is related to the speed of the cut-off mechanism so that the dough pieces produced by each extruder form a single uniformly spaced line. The extruders are fed from a common supply through individual inlets and means are provided to balance the flow through the nozzles.
摘要:
Es wird ein Verfahren und eine Einrichtung beschrieben, mit deren Hilfe in einer Plattensäge (10) von einer Werkstückplatte (26) abgetrennte Plattenteile (26ʹ) einzeln derart einer Fördervorrichtung zugeführt werden, dass nach jedem Trennschnitt die Werkstückplatte (26) zur Neueinstellung mit einer Geschwindigkeit in Vorschubrichtung weitertransportiert werden kann, die grösser ist als die Geschwindigkeit, mit der das Plattenteil (26) der Fördervorrichtung zugefördert wird. Hierzu wird vorgeschlagen, das abgetrennte Plattenteil (26ʹ) nach erfolgtem Trennvorgang über die Auflageebene (14) anzuheben und neben der in der Plattensäge (10) in einer neuen Trennstellung festgelegten Werkstückplatte (26), zu dieser in Vorschubrichtung versetzt, auf die Fördervorrichtung (30) aufzulegen.
