Embodiment Construction

[0086] According to the drum type winding equipment 1 of the present invention in figure 1 The preferred embodiment shown in is realized in conjunction with a drum cutting device designed as a carrier roll winding device. The basic components of the drum cutting device 1 are: an uncoiling device 4, a cutting section 6, and a winding mechanism 2 arranged in the area of ​​the paper web roll-up, which is substantially the same in width as that provided on the drum cutting device 1. In the unwinding device, the paper web M of the same working width of the previous paper machine (not shown here) is withdrawn from the mother cylinder 5, and in the cutting section 6, it is possible to produce the webs M' The selected width specification divides the web M longitudinally according to the web running direction.

[0087] For this purpose, the cutting unit 6 usually comprises, as a basic component, a generally disc-shaped cutting device, shown here in the form of an upper knife 7 a and a...

Abstract

The invention relates to a method for wrapping a sheet of material and a roll cutting device. According to the invention, According to the invention, a roll winding apparatus is used for winding a material web or paper card web onto a winding core, preferably winding onto a sleeve to form a reel. During a winding process, at least one roller presses against the reel. In order to improve the winding structure, especially stabilize the winding region, the roll winding apparatus comprises a winding hardness generator which does not contact with at least one reel.

Description

technical field [0001] The invention relates to a drum winding device for winding a material web, in particular a paper or cardboard web, onto at least one winding core, preferably a winding sleeve, into a roll, At least one roller bears against the mandrel during winding. [0002] Furthermore, the invention relates to a method for winding a material web, in particular a paper or cardboard web, onto at least one winding core, preferably a winding sleeve, to form a roll by means of a drum winding device, wherein , the drum winding device has at least one roller, which rests against at least one drum during the winding process and by means of which the tension (spannung) and / or stretch existing in the material web is influenced . [0003] The invention is explained below in connection with the treatment of a paper web. However, the invention can correspondingly also be used in other similarly operable webs. This is, by way of example and not exhaustive, a web made of cardboa...
