Problems solved by technology

The effort incurred by the plant operator is also high and (due to the reinforced layer) considerably more material has to be removed or recovered
[0017] In the case of the processing of product webs, for example made of textiles, plastic or paper, roll changes always lead to an interruption of the processing method and thus to a reduction in the productivity of the method

Embodiment Construction

[0041] exist figure 1 A device 100 , which is shown schematically in a view transverse to the advancing movement direction V of the product web W, is used for reinforcing a product web with a nonwoven fabric. The product web has filaments 1 made of thermoplastic material. In order to provide these filaments, at least one spinning box 2 is usually provided. exist figure 1 The device shown in has two spinning boxes 2 . By means of the spinning box 2, the correspondingly released threads 1 are placed on the upper side O of the screen belt 7 or, if necessary, on the layer of threads already on the screen belt 7. The screen belt 7 is formed as a continuous loop guided around the guide rollers 3 , 4 , 5 , 6 . For the purpose of undisturbed laying of the filaments, an air flow L is generated in the corresponding laying area 8 of the corresponding spinning box 2 by means of a suitable blower, not shown in the drawings, said air flow from above Down through the screen belt 7.

Abstract

The invention relates to a method for processing a product web (W), wherein the product web (W) is transported in an advancing motion direction (V) and guided by a first processing roller (16') in a first working position The first processing gap (26) formed with the cooperating tool (17) has the following steps in order to replace the first roller: - provide the second roller (16 ", 31); - deflect the second roller (16 ", 31) Move into the second working position, in which the second rollers (16", 31 ) form a second processing gap (30, 32) with the cooperating tool (17); - place the first processing rollers ( 16') into a first park position in which the first processing roller does not form a processing gap with the counter tool (17).

Description

technical field [0001] The present invention relates to a method for processing a product web, wherein the product web is transported in the forward movement direction and guided through a first processing gap formed by processing rollers and cooperating tools. The invention also relates to a device for implementing the treatment method. Background technique [0002] It is known to transport the product web for its processing in the forward movement direction and guide it through the processing gap formed by the processing rollers and the cooperating tools in the working position. Such product webs can be in particular nonwovens, textiles, plastics or paper and also product webs made of composite materials with one or more of these materials. [0003] In such a process there is often a need to replace the process rollers. By way of example, it is stated that: [0004] - The wear limit of the processing rollers is reached. [0005] - Altering the treatment results by repl...
