Embodiment Construction

[0042] figure 1 and figure 2The part of the plant 1 for processing a material web 2 which is responsible for supplying the web is shown. The material web 2 is provided on a reel 21 , which is supported on the roller 11 of the device 1 . The uncoiled material web 2 is fed to the processing device by means of a plurality of deflection rollers 12 which are fixedly and rotatably arranged on a frame 13 of the device 1 . Actual processing devices, such as printing stations or embossing stations, are not shown in the figures.

[0043] If the material web is introduced obliquely when loading the new reel 21 , different tensile forces on the opposite sides 22 , 23 of the material web result when the material web 2 is drawn in. This can lead to web breaks, which require the device 1 to be taken out of operation.

[0044] To prevent this, the device 1 includes a web guide 3 . The web guiding device comprises two frame elements 31 , 32 which are pivotably mounted with their respecti...

Abstract

The invention relates to a web guiding device (3) for guiding a material web (2), in particular a film web, having a first and a second frame element (31, 32) which: - pivotally supported on the first shaft (33) in the respective first end region (311, 321), - pivotally supported in the respective second end region (321, 322) via the The web guide rollers (34) are connected, and - are connected via a second shaft (35), which is connected to the first shaft (33) by means of a fixing element (37).

Description

technical field [0001] The invention relates to a web guiding device for guiding a material web, in particular a film web, and a device for processing a material web, in particular a film web. Background technique [0002] When processing material webs, such as film or paper webs, in embossing plants, printing plants or the like, the material webs are usually supplied on reels, uncoiled for processing, transported by deflection rollers to a processing station and sometimes then wound up again rise. [0003] If the material web is drawn in obliquely or asymmetrically when a new roll is provided, different tensile forces act on opposite edge regions of the material web, which can lead to bending, folding or breaking of the material web. [0004] However, in some cases it may also be desirable to pull in the material web asymmetrically, that is to say obliquely, for example in order to ensure that the edge regions of the material web are under high material stress (and thus sm...
