Problems solved by technology

In this known device, however, the nonwoven web is subjected to unfavorable forces when it is fed into the calender gap.
Especially at elevated machine speeds and falling basis weights, the forces for pulling out the nonwoven web are partly too great for the nonwoven web and lead to degraded or damaged
The result may therefore be significant transverse shrinkage (web reduction) or also poor quality nonwoven web edges

Embodiment Construction

[0018] FIG. 1 shows a device for stacking and transporting a nonwoven web 1 consisting of plastic threads 2 . The plastic filaments 2 emerge in a molten state from suitable spinneret holes not shown and are finally deposited on the surface of the laying belt 3 for the nonwoven web 1 . The overlapping web belt 3 is in this embodiment a continuously circulating overlapping web belt 3 guided by rollers 4 , 5 . In FIG. 1 , on the right-hand side of the horizontal part of the superimposed belt 3 which receives the nonwoven web 1 , there is a first roller 4 which is designed as a deflection guide roller in this exemplary embodiment. Here, the continuously circulating superimposed web belt 3 is diverted downwards around the first roller 4 from its horizontal transport position for the nonwoven web 1 .

[0019] According to the invention, the first roller 4 has outlet openings 7 distributed along its roller jacket 6 . The discharge holes 7 are provided for the discharge of a fluid m...

Abstract

A process accumulates a feed supply of non-woven man-made fibers and transports these on a belt over a release-point drum. The drum (4) esp. has numerous perforations (7) in the mantle linked to an interior supply of pressurised air. Also claimed is a commensurate assembly in which air is pumped into the drum via a hollow axle (8) and discharged through the perforations (7) and conveyer belt.

Description

technical field [0001] The invention relates to a device for stacking and conveying nonwoven webs made of threads, especially plastic threads, comprising a continuous loop of stacking belts guided by rollers, on which are stacked for Plastic filaments of nonwoven fabric webs. In the context of the present invention, a thread here refers to a completely ordinary fiber or filament, by means of which a nonwoven web can be formed. Particularly preferably, the invention relates to the stacking and conveying of nonwoven webs composed of plastic threads. Within the scope of the present invention, a plastic thread means, on the one hand, a filament which is formed as a theoretically continuous thread or as an endless filament. However, plastic filaments basically also refer to shorter fibers from which nonwoven webs can be produced. Background technique [0002] The non-woven fabric fiber web or uncured non-woven fabric fiber web stacked on the stacking mesh belt is transferred t...
