Provided is an adhesive film production apparatus for producing an adhesive film having an adhesive layer on a base material layer, the adhesive layer having an elastic modulus at 230° C. of 1 MPa or greater and having a glass transition temperature higher than normal temperature, the adhesive film production apparatus including a feeding roller; a cutting part; and a plurality of winding cores, wherein the raw film of the adhesive film is wound on the feeding roller such that the adhesive layer faces outward, and wherein in the conveyance path of the adhesive film traveling from the cutting part toward the winding core, the number of times of the adhesive layer of the adhesive film bending in a convex manner is set to be equal to or more than the number of times of the adhesive layer bending in a concave manner.

The invention relates to a winding apparatus for winding a material web traveling in a direction of travel, having at least one blade for cutting the material web in a web direction into a plurality of partial material webs, and having a folding apparatus for folding the edges of the partial material webs. To furnish a winding apparatus that enables a material web with folded edges to be wound with as little wrinkling as possible, a folding element is furnished for each edge of the partial material webs. The at least one blade may be moved transversely to the direction of travel using a first oscillating apparatus. Using a second oscillating apparatus, the folding elements for the left-hand edges of the partial material webs, as viewed in the direction of travel, may be moved transversely to the direction of travel. Using a third oscillating apparatus, the folding elements for the right-hand edges of the partial material webs, as viewed in the direction of travel, may be moved transversely to the direction of travel. The first oscillating apparatus, second oscillating apparatus and third oscillating apparatus may be controlled by a control unit in such a manner that the folded edges of the partial material webs may be wound at an offset to one another.

To provide (i) a method for producing an assembly capable of protecting a film from external force during, for example, transport and (ii) such an assembly, a method for producing an assembly includes a step of inserting a pillar-shaped core member through a plurality of separator rolls and a buffer member(s) made of a flexibility material and provided between separator rolls such that the separator rolls and the buffer member(s) are arranged alternately.

The invention describes a roll-removal device by means of which a plurality of rolls which have been wound to completion are transported away from a winding shaft having a displacement device for displacing the rolls relative to the winding shaft, in order to withdraw the rolls from the winding shaft, having a receiving device for receiving the rolls, and having a transfer device for transferring the rolls from the displacement device to the receiving device, wherein the rolls can be rolled freely at least in certain regions, the rolls rolling about their rolling axes.

By means of this device for changing the position of the rolls axes, the roll axes of two adjacent rolls can be moved to an angle of less than 180 degrees in relation to one another.

The rewinding machine (1) comprises: a winding station (3) with winding members (5, 7) operated by winding motors In (8.1, 8.2); an unwinder (31.1, 31.2) with an unwinding member (35.1, 35.2) operated by at least one unwinding motor (38.1, 38.2); guide roller (43.1, 43.2) along a feed path (P) of the web material (N, N2). There is associated with the guide roller (43.1, 43.2) at least one load sensor (42.1, 42.2), adapted to detect a parameter proportional to the tension of the web material (N; N2) guided around the guide roller (43.1, 43.2). There is also provided a control unit (71) adapted to modulate a difference in speed between the winding members (5, 7) and the unwinding member (35.1, 35.2) as a function of a signal coming from the load sensor (42.1, 42.2).
