Method for manufacturing pile carpet

Abstract

The invention relates to a method for manufacturing pile carpet or pile carpet tiles, wherein a pile yarn (8) is connected via a pile thread holder (1) to at least a primary backing (7), wherein the pile thread holder (1) comprises a plurality of pile thread guide channels (2) which perforate the pile thread holder (1) through two opposite sides, wherein the pile thread holder (1) is provided between a pile thread gripping station (14) on a first perforated side (5) and a primary backing (7) on a second perforated side (6) such that the pile yarn (8) is arranged via the first perforated side (5) through a pile thread guide channel (2) to the second perforated side (6) onto, into or through the backing (7).

Description

technical field [0001] The present invention relates to an improved method for the manufacture of pile carpets, which method is particularly advantageously applied to cut pile carpet tiles, more particularly V-shaped piles. In particular, the present invention relates to a continuous one-step process from backing to finished carpet or carpet tile. The invention also relates to a pile carpet, in particular a pile carpet tile produced using this method. The invention further relates to a device for carrying out the method. Background technique [0002] The invention is particularly applicable to cut pile carpets. Cut pile carpets are characterized by a surface formed by upstanding pile threads in the form of (cut) thread ends, which are attached to a carrier (or backing) either mechanically or by adhesive. [0003] Carpet tiles are typically manufactured by cutting wide carpets on a tumbler machine. [0004] Classic manufacturing techniques include tufting and weaving. ...

AI Technical Summary

Problems solved by technology

[0006] Disadvantages of tufting are: (1) different manipulations after tufting are necessary to anchor the pile yarns and improve comfort; (2) limitations of the carrier material used; (3) very limited patterning options, because the yarn must remain in the needle during the tufting process

[0011] Disadvantages of weaving are: (1) slow production process, which causes a lot of vibration (the machine must be built on a vibration-free concrete base); (2) very large and expensive machine; (3) due to inactive threads (color) Massive loss of pile yarns due to continued stretching and weaving into the "back" (bottom) of the carpet; (4) presence of pile direction corresponding to production direction; (5) finishing of the backside in large energy-consuming latex furnaces (pile anchoring); (6) the rug must still be cut and hemmed to prevent fraying of the edges; (7) multiple materials in one rug, especially the latex used to anchor the pile, lead to duplication Difficult and incomplete utilization; and (8) complex and not very flexible designs in the process of designing loose-laid carpet on a four-meter wide machine, loss of backing

[0014] The problem is: in order to obtain a cut pile carpet, only a single thread can be inserted to finally be fixed in a J shape between two backings

In addition, the possibility of damage to the pile yarn is even greater
