Abstract
A film winding device for winding a film web to a film bale is disclosed having a winding apparatus and a feed apparatus. The feed apparatus includes a feed slide, a contactor and at least one tensioner, the tensioner is attached to the feed slide and the tensioner is located before the contactor so that the tensioner can set a film tension of the film web. The tensioner includes a cylinder, and the cylinder comprises a micro-porous surface at least in the region of the arc.
Claims20
A film winding device for winding a film web to a film bale comprising a winding apparatus and a feed apparatus,
- wherein the winding apparatus comprises at least one winding core and is configured to wind a film bale on the winding core,
- wherein the feed apparatus comprises a feed slide, a contactor and at least one tensioner,
- wherein the contactor is attached to the feed slide and is located adjacent to the winding core in such a way that the contactor is able to guide the film web to the winding core or to the film bale on the winding core,
- wherein the tensioner is attached to the feed slide and the tensioner is located before the contactor in the direction of travel of the film web in such a way that the tensioner is able to set a film tension of the film web,
- wherein the tensioner comprises a cylinder with a circumferential surface, wherein the cylinder has an arc in the cross-section and the circumferential surface comprises at least a micro-porous surface in the region of the arc.
A method for winding a film web or a film web made of battery separator film by means of a film production system comprising at least one film stretching unit and one film winding device, or by means of a film winding device,
- the film winding device comprising a winding apparatus and a feed apparatus, wherein the winding apparatus comprises at least one winding core and is configured to wind a film bale on the winding core, wherein the feed apparatus comprises a feed slide, a contactor and at least one tensioner, wherein the contactor is attached to the feed slide and is located adjacent to the winding core in such a way that the contactor is able to guide the film web to the winding core or to the film bale on the winding core, wherein the tensioner is attached to the feed slide and the tensioner is located before the contactor in the direction of travel of the film web in such a way that the tensioner is able to set a film tension of the film web, wherein the tensioner comprises a cylinder with a circumferential surface, wherein the cylinder has an arc in the cross-section and the circumferential surface comprises at least a micro-porous surface in the region of the arc.
