Abstract
A device for spreading, compressing or guiding a running material web formed by a rotatably supported roll. The roll has a number of slats distributed over its circumference which can be displaced transversely to the direction of the web. The slats are actively connected with control devices that cause a longitudinal displacement of the slats. Alternating slats are actively connected to different control devices. Half of the slats have an adhesive surface and the other half has a sliding surface.
Claims10
A device for spreading, compressing and guiding a running material web comprising:
- a rotatable roll (5);
- a series of slats (13, 13′) disposed around the circumference of the roll (5), said slats extending transverse to a moving direction (L) of the material web, wherein each slat comprises a first half and a second half, said first half at least partially having a greater adhesive power than the remaining second half;
- and
- a control device (14, 14′) disposed at each end of the roll (5) for periodically displacing the slats (13, 13′) transversely to the material web during rotation of the roll (5).
