摘要:
The invention relates to a device (1) for guiding a material web strip in a running direction (2), having a housing (3), in which a negative pressure generation system is arranged. It is intended to guide the material web strip safely. To this end, it is provided that a plurality of vacuum chambers (7-10 12) are arranged one after another in the running direction (2) in the housing (3), of which each comprises at least one suction device (20-25).

A vacuum conveyor is provided comprising an endless perforated belt which extends over a first vacuum plate (20) and a second vacuum plate (30), which vacuum plates may be maintained at different air pressures are be situated at different angles relative to horizontal. An apparatus for cutting and transporting sheet materials is provided comprising the vacuum conveyor according to the present invention and a rotary die cutter situated such that an emerging portion of a cut workpiece can become held by the vacuum conveyor before it is fully separated, enabling pattern-cut sheet materials to be cut and transported to a destination such as a laminating nip with accurate registration.

Beschrieben wird ein Saugbändertisch, an dem zulaufseitig und ablaufseitig die Haltekräfte auf zu transportierende Bogen steuerbar sein sollen. Der Saugbändertisch 1 ist dazu mit drei Saugkammern versehen. Dabei wird eine der Saugkammern als Hauptsaugkasten 11 unabhängig von zwei Querkästen 13, 14 mit Saugluft versorgt. Die Querkästen 13, 14 sind demgegenüber gemeinsam mit einem Sauglufterzeuger 6 verbunden. In der Verbindung zwischen den Querkästen 13, 14 und dem Sauglufterzeuger 6 ist eine Stellvorrichtung in Form einer Steuerklappe 19 vorgesehen, die die getrennte und unterschiedlich gesteuerte Saugluftzufuhr zu den beiden Querkästen 13, 14 erlaubt.

A liquid ejecting head (20) has a plurality of nozzles (30) which are operable to eject liquid toward a medium (M). A transporter (11) is operable to transport the medium (M) relative to the liquid ejecting head (20) in a first direction. The transporter (11) is provided with a plurality of first holes (40) adapted to receive the liquid that has been ejected toward outside of the medium (M).
