Embodiment Construction

[0022] exist figure 1 with figure 2 The principle of the web folding device in the embodiment of the table-top or cross-folding machine 1 is shown by way of example and only schematically. Instead of the crossfolder 1 , the oblique folder can also receive and lay down the nonwoven. The fiber web 3 is transported from a carding device (not shown) to the input belt 2 of the crossfolder 1 . An upper carriage is arranged in the crossfolder 1 , only deflection rollers 6 being visible in this view. Furthermore, the cross-folding machine 1 has a laying carriage, in which a laying roller 10 for the matching belt 13 and a laying roller 9 for the feed belt 2 are shown. Between the laying roller 10 of the mating belt 13 and the laying roller 9 of the infeed belt 2 a so-called laying nip 11 is arranged, from which the fiber web 3 exits and is laid onto a laying roller arranged below the laying carriage. Output belt 15 on. Depending on the direction of travel, the two laying rollers ...

Abstract

The invention relates to a web storage table for a web folding plant having a folder which lays the web folded on a delivery belt (15), wherein the web storage table (20 ) has an endless belt (21) that moves at a pulsating velocity (v 22 ) receives the folded web from the output belt (15) and feeds the web at a constant speed (v 23 ) to downstream machines for further processing or consolidation of the folded web. The invention also relates to a method for operating a network storage station. The invention is characterized in that the endless belt (21) of the net storage table (20) is driven at the entrance by means of a first drive and at the exit by means of a second drive, wherein the first drive corresponds to the movement and speed profile of the folding machine coupling.

Description

technical field [0001] The invention relates to a web storage station for a web folding plant having a folder which lays the web folded on an output and to a method for operating the web storage station. on the belt, where the storage table has an endless belt that receives the folded web at a pulsating speed from the output belt and delivers it at a constant speed to a downstream machine for further processing or consolidation of the folded fiber network. Background technique [0002] For the production of multilayer nonwovens, carding devices with subsequent web folding devices are usually used. In a carding machine, fiber batts are conveyed on the input side, are debonded until individual fibers are formed, and are output on the output side as an unreinforced, textile planar structure, ie a fiber web. [0003] A web folding device designed as a table folder or oblique folder transports the web to an output belt arranged at 90° to the input direction and lays the web on ...
