Abstract
The present invention is directed to an angle-bar arrangement for deflecting material webs on an angle-bar jacket (1) which is provided with a plurality of air outlet openings (2). Closing elements (6), which seal off respective air outlet openings (2), are movably accommodated in the angle-bar jacket (1). Compressed air enters into the hollow space bounded by the movably accommodated closing elements (6). The movable closing elements (6), whose outer contour (7) corresponds to the inner wall (3) of the angle-bar jacket (1), are driven independently of one another by actuators (18, 20).
Claims19
An angle-bar for deflecting material webs in a rotary press comprising:
- an angle-bar jacket having an axial length and a width, the axial length being greater than the width, and having a plurality of axially-spaced air outlet openings;
- closing elements for sealing off the air outlet openings, the closing elements being axially movable in the angle bar jacket, compressed air being fed into a hollow space of the angle-bar jacket delimited by the closing elements;
- and
- actuators, the closing elements being guided in the angle-bar jacket via rails and being mutually independently movable by the actuators;
- the closing elements having an outer curved surface matching an inner curved surface of the angle-bar jacket.
A method for adjusting an angle-bar for deflecting material webs in a rotary press, the angle-bar having an angle-bar jacket having an axial length and a width shorter than the axial length, the angle-bar jacket having a plurality of axially-spaced air outlet openings and closing elements for sealing off the air outlet openings, compressed air being fed into a hollow space of the angle-bar jacket delimited by the closing elements, the method comprising the steps of:
- moving axially one of the closing elements in the angle-bar jacket via an actuator in a tracked motion;
- and
- moving independently another of the closing elements in the angle-bar jacket via another actuator in a tracked motion;
- wherein the closing elements have an outer curved surface matching an inner curved surface of the angle-bar jacket.
An angle-bar for deflecting material webs in a rotary press comprising:
- an angle-bar jacket having a plurality of axially-spaced air outlet openings;
- closing elements for sealing off the air outlet openings, the closing elements being movable in the angle bar jacket, each closing element capable of closing at least two of the axially-spaced air outlet openings, compressed air being fed into a hollow space of the angle-bar jacket delimited by the closing elements;
- and
- actuators, the closing elements being guided in the angle-bar jacket via rails and being mutually independently movable by the actuators.
