摘要:
Methods and systems for preventing wrinkles in a web passing through an accumulator. The accumulator comprises a plurality of rollers including at least one roller having an axis of revolution movable toward and away from the axis of revolution of another roller to release and store varying amounts of the web. At least one of the rollers has a nominally flat outer surface and at least one of the rollers has a profiled outer surface.

摘要:
A winder (10) for winding a web (36) to produce a rolled product is provided. The winder includes a web (36) transport apparatus (34) that is used for conveying the web (36). Also included in one exemplary embodiment is a plurality of independent winding modules. The winding modules (1, 2, 3, 4, 5) are independently positioned to independently engage the web (36) as the web (36) is conveyed by the web transport apparatus (34). The winding modules (1, 2, 3, 4, 5) may be configured to wind the web (36) to form a rolled product by center winding, surface winding, and combinations of center and surface winding. The winding modules (1, 2, 3, 4, 5) are structurally and operationally independent of one another where if one module is disabled, another may still operate to produce the rolled product without shutting down the winder.

Die Transportwelle für eine Falzmaschine umfasst einen Wellenkörper (12), der einen ringförmigen Querschnitt aufweist, und wenigstens ein auf dem Wellenkörper (12) drehfest angebrachtes Transportelement (14, 16) mit ringförmigem Querschnitt. Um mit konstruktiv einfachen Mitteln eine Transportwelle für eine Falzmaschine mit geringem Gewicht und geringer Durchbiegung zu schaffen, ist der Wellenkörper (12) aus Kohlenstofffaserkunststoff hergestellt.
摘要:
A paper stacker for use with a printer which prints connected sheets that are to be stacked in a folded relationship having a surface for receiving the paper with a frame surrounding the paper that is raised in relationship to the paper in order to maintain paper within the confines of the frame as the frame moves upwardly. The frame is balanced by a constant force spring, and is indexed by optical sensors. The frame includes two adjustable fences for variously sized paper which adjustably moves with paddles to press the paper edges downwardly in the stack. Pinch rollers for driving the paper include low inertia drive rollers formed of a relatively low density plastic material with a pair of idler rollers. To improve stacking, ironing tractor idler rollers iron the tractor perforations, and chains orient the catenary stacking movement.

摘要:
The present invention provides a web splicing method and a web splicing apparatus with which a line velocity on an output side of the splicing apparatus does not fluctuate through a web splicing operation. The method and apparatus are further operable to maintain a line velocity at a predetermined velocity after the web splicing operation. The method of the present invention includes the steps of: connecting a second web Wb fed out from a second roll B to a first web Wa ; cutting off the first web Wa at a position between a point at which the second web Wb is connected to the first web Wa and a first roll A ; spinning the second roll B to feed out the second web Wb; obtaining a value of a diameter of the second roll B based on a state of an accumulator 4 ; and controlling a circumferential velocity of the second roll B based on the obtained diameter.
