摘要:
A non-woven fabric is produced by the transportation of a fiber flow at an angle which is less than 90.degree. to the transport direction of the non-woven fabric to be manufactured, with the feed rate of the fiber flow being controlled, the fibers which are to form a fiber layer being placed next to one another, and with the formed fiber layer being simultaneously, and in the lateral border areas of the fiber layers, being consecutively, combined with the preceding fiber layer, reinforcing the produced non-woven fabric. The angle of the fiber flow to the transport direction of the non-woven fabric to be manufactured is set between 0.degree. and 89.degree.. The controlling of the fiber flow comprises monitoring of the quantity feed rate and/or dissociation of the fiber flow and/or fiber mixing, immediately prior to the formation of a fiber layer. In order to combine the formed fiber layer with the preceding fiber layer, this is placed adjacent to the formed fiber layer, or placed on at least one formed fiber layer.

A non-woven fabric is produced by the transportation of a fiber flow at an angle which is less than 90.degree. to the transport direction of the non-woven fabric to be manufactured, with the feed rate of the fiber flow being controlled, the fibers which are to form a fiber layer being placed next to one another, and with the formed fiber layer, including lateral border areas of the fiber layers, being combined with the preceding fiber layer, reinforcing the produced non-woven fabric. The angle of the fiber flow to the transport direction of the non-woven fabric to be manufactured is set between 0.degree. and 89.degree.. The controlling of the fiber flow comprises monitoring of the quantity feed rate and/or dissociation of the fiber flow and/or fiber mixing, immediately prior to the formation of a fiber layer. In order to combine the formed fiber layer with the preceding fiber layer, this is placed adjacent to the formed fiber layer, or placed on at least one formed fiber layer. In the present apparatus for the execution of the method for the production of a non-woven fabric, one or more fiber feed rate control devices, each connected to a traverse drive unit, are arranged to one or more fiber flow transport devices, below an angle of 90.degree. to the transport direction of the non-woven fabric to be manufactured, and assigned to an already known non-woven fabric transport device. The fiber feed rate control device contains a rotation unit. The fiber feed rate control device is arranged at the beginning or above the non-woven fabric transport device. The traverse drive is formed as a pivot drive. In order to dissolve the fiber flow consisting of fibers, adhesively connected to one another, the fiber feed rate control arrangement contains a dissolving roll. The fiber feed rate control device and the traverse drive unit have variable speed motors for the required adjustment of the fiber flow feed rate to the delivery speed of the non-woven fabric, depending on the surface measurement of the non-woven fabric to be produced and the reinforcement speeds. The traverse drive unit has working width position stops.

Warp knit fabrics, especially sewn-knitted fabrics, are produced by a method and apparatus whch results in single and multiple layer sloping fabrics having oblique and diagonal endless filling threads with respect to the boundary of the fabrics. Spaced-apart chain conveyors transport a plurality of filling-thread sections, each of which contains a plurality of endless filling threads, to a stitch-forming site. The plurality of filling-thread sections are held between and transported by the conveyors by a plurality of hooks in the conveyors. Filling thread sections are laid onto the hooks by at least one filling laying device having a guide means for laying the filling thread sections onto the hooks. The filling laying device, guided by a pair of guide rods adjustably positioned obliquely and diagonally with respect to the direction of transportation of the chain conveyors, moves back and forth between the chain conveyors obliquely and diagonally with respect to the direction of transportation of the chain conveyors so that the filling thread sections are laid onto the hooks at an oblique and diagonal angle to the boundary of the fabric. Depending on the number of filling laying devices utilized, and the oblique and diagonal movement of each, single and multiple sloping products are produced wherein filling thread sections within a layer lay parallel to each other or overlap each other at various angles, and different layers of the fabric have mutually-crossing filling thread sections disposed obliquely or perpendicularly to the boundary of the fabric as desired.

A method and apparatus for the production of a textile strip, by preparing and aftertreating an intermediate product, with the product textile strip being a new article of manufacture and having long weft elements, especially long weft threads, provided diagonally to the strip length, intersecting one another, and connected by longitudinal rows of stitches. The apparatus includes a device on a warp knitting machine, particularly a thread knitting machine, having at least one movable weft laying device, in order to work long weft elements or weft threads, which extend over the entire working width, into the textile strip. A strip of a weft and warp knit is initially produced as intermediate product, having long weft elements, particularly long weft threads, connected by stitches, by subsequently bringing the weft threads into a very oblique position relative to the strip length, by diagonal displacement of the strip of the weft and warp knit, by doubling the weft and warp knit, so that the oblique long welf threads of one main layer of the doubled material intersect the oblique long weft threads of the other main layer, and by finally fastening the two main layers of the doubled welf and warp knit with a top binding consisting of a number of rows of stitches running along the weft and warp knit.

摘要:
The present invention is directed to a warp stitching machine comprising a means for guiding a warp element onto a base material on which the warp element is to be formed into a warp of stitches. This guiding means for the chain element is situated on a bracing means in the warp stitching machine, and is preferably in the form of oblique channels for directing the warp element onto the base material.
