Embodiment Construction

[0055] First application: holding a nonwoven belt during transport

[0056] now refer to Figure 1-3 (first variant) and Figure 4-6 (Second Modification) The first application of the present invention, which is to hold a selvedge of a nonwoven tape during conveyance, will be described in detail.

[0057] refer to figure 1 (first variant) and Figure 4 (Second variant), in the particular application to which these figures are directed, a first upper conveyor belt 1 comprising a conveyor belt (conveying surface) 1a driven by a roller 1b is used to convey a first nonwoven web W1 along the conveying direction MD1 To a rotating transfer roller 3 mounted at the end of the first conveyor belt. This rotating transfer drum 3 can continuously transfer the first nonwoven web W1 onto a second transfer surface formed by the belt 2a of a second lower conveyor belt 2, which is located below the first conveyor belt 1 and the transfer drum 3. . The transfer roll 3 preferably comprises a...

Abstract

The method involves charging electro-statically a non-woven fabric band and a mobile transporting surface to adhere the band on the transporting surface in a longitudinal carriage zone (ZM). Dimension of the carriage zone measured in a direction perpendicular to a transporting direction (MD) is less than width (L) of the band.

Description

technical field [0001] The present invention relates to an improvement in the field of textiles for conveying a nonwoven web over a conveying surface and, if desired, in some applications, the operation of the longitudinal edges of the nonwoven web being conveyed. The invention finds application in various types of nonwovens (carded nonwovens, "spun" nonwovens based on continuous fibers, "meltblown" nonwovens obtained by melting Cloths, "airlaid" nonwovens obtained by pneumatic means), and preferably use the present invention prior to curing of the nonwoven. Background technique [0002] non-woven fabric [0003] Herein, various fiber and / or silk cloths or superpositions of fiber and / or silk cloths are collectively referred to as "nonwoven tapes", regardless of the method of manufacture of these cloths and the type of fibers or threads. In particular, the nonwoven web may consist of one or more fibers or filaments selected from the following types: carded nonwovens, "airla...
