Abstract
In an unroll device provision is made for at least one unroll stand which comprises two lugs lodged in bearing supports. The bearing levers are horizontally movable individually. Furthermore, a supporting shaft is run on the bearing supports of an unroll stand in such a way that it can be shifted parallel allel to itself, but also out of its base position in a horizontal plane.
Claims7
An unroll device with at least one unroll stand (1, 1a), comprising
- a machine frame (4), which has two bearing stands (5, 5′) spaced apart;
- bearing supports (10, 10′, 10a;
- 35, 35′, 35a), which are guided substantially horizontally movably on the bearing stands (5, 5′);
- shifting drives (12, 12a;
- 37, 37a) acting on the bearing supports (10, 10′, 10a;
- 35, 35′, 35a);
- a supporting shaft (14, 14a), which has a central longitudinal axis (16, 16a), and the ends of which are run on the bearing supports (10, 10′, 10a;
- 35, 35′, 35a);
- lugs (17, 17′, 17a), which are guided on the supporting shaft (14, 14a) non-rotatably relative thereto, but displaceably in the direction of the central longitudinal axis (16, 16a);
- centering pivots (24, 24′, 24a) for holding a reel (28), which are mounted on the lugs (17, 17′, 17a) and define an unrolling axis (26, 26a);
- and
- at least one lifting drive (22, 22′, 22a, 22′a) coupled to the supporting shaft (14, 14a);
- wherein the supporting shaft (14, 14a) is run on the bearing supports (10, 10′, 10a;
- 35, 35′, 35a) such that its central longitudinal axis (16, 16a) is not only displaceable parallel to itself, but is also pivotal about a base position substantially in a horizontal plane;
- and
- wherein the shifting drives (12, 12′;
- 37, 37′) are individually operable.
