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.

1. 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
1. 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 of every other slat at least partially having a greater adhesive power than the corresponding second half, said corresponding second half being provided with a sliding surface, and said second half of the remaining slats having a greater adhesive power than the corresponding first half of the remaining slats, said corresponding first half of the remaining slats being provided with a sliding surface, so that the material web, when viewed in the moving direction of the web, is engaged by successive slat halves in an alternating adhesive and sliding manner; 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). 2. The device according to claim 1, wherein the slats having the greater adhesive power are coated with an adhesive coating (20). 3. The device according to claim 1, wherein every other slat (13, 13') is associated with the same control device (14, 14'). 4. The device according to claim 1, wherein the control devices (14, 14') comprise control disks (15, 15') and guide rods (18) being distributed around a circumference of said disks, for engaging said control disks, said guide rods being actively connected with the slats (13, 13'). 5. The device according to claim 4, wherein said control disks (15, 15') are pivotable in their angular positions with respect to the axis of rotation (8) of the roll (5). 6. The device according to claim 1, further comprising slide guides (9) for supporting the slats (13, 13'), said slide guides (9) being axially aligned with the roll (5), and stationarily supported on the rotatable roll (5). 7. The device according to claim 1, wherein the control devices (14, 14') each are actively connected with a servo-drive (19, 19').
