CLAIMS
1. Method for manufacturing pile carpet or pile carpet tiles, wherein a pile yarn is connected via a pile thread holder to at least a primary backing, wherein the pile thread holder comprises a plurality of pile thread guide channels in a matrix-like configuration which perforate the pile thread holder through two opposite sides, wherein the pile thread holder is provided between a pile thread gripping station on a first perforated side and a primary backing on a second perforated side, and the pile yarn is arranged via the gripping station from the first perforated side through a pile thread guide channel to the second perforated side through the primary backing.
2. Method for manufacturing a loop-pile carpet or loop-pile carpet tiles, wherein a pile yarn is connected via a pile thread holder to at least a primary backing, wherein the pile thread holder comprises a plurality of pile thread guide channels in a matrix-like configuration which perforate the pile thread holder through a first side and a second side, wherein the pile thread holder is provided below a pile thread gripping station and a primary backing is arranged on the first side, and the pile yarn is arranged via the gripping station through the primary backing from the first side through a pile thread guide channel to the second side.
3. Method as claimed in claim 1, wherein the arranging of a pile yarn comprises the following steps of: a. bringing the pile yarn to length in the gripping station; b. inserting at least one pile yarn via the first perforated side into a part of a pile thread guide channel; c. cutting the pile yarn to the desired length; d. inserting the cut pile yarn further through the pile thread guide channel to the second perforated side; and e. inserting the pile thread further through the primary backing.
4. Method as claimed in claim 3, wherein the pile yarn is gripped in a central part of the pile yarn brought to length using a gripping pin; and in that the gripping pin first engages the pile yam and then passes through the pile guide channel and the primary backing with the pile yarn.
5. Method as claimed in claim 1, wherein the pile yarn is gripped in a central part of the pile yam brought to length using a gripping pin, and in that the gripping pin first passes through the backing and the pile guide channel, then engages the pile yarn and returns therewith through the pile guide channel and the primary backing.
6. Method according to any one of claims 1-5, wherein the pile yarn is cut to length with a shears when the pile yarn is located partially in the pile thread guide channel.
7. Method according to any one of claims 1-6, wherein the primary backing is pre-perforated with perforations corresponding to the perforations of the pile thread holder for the purpose of receiving the tip of the pile yarn.
8. Method according to any one of claims 1, 3, 4 and 5, wherein the primary backing is supported by a bottom plate which comprises recesses for receiving the tip of the pile yarn.
9. Method according to any one of claims 1, 3, 4 and 5, wherein a secondary backing is arranged against the primary backing, while the pile yarn is in the pile thread guide channels.
10. Method as claimed in claim 9, wherein fixation parts of the pile yarn are pressed between the primary backing and the secondary backing such that after pressing they have a flange form.
11. Pile carpet manufactured with the method according to any one of claims 1, 3, 4 and 5, comprising a perforated primary backing provided with an implanted V-pile yarn, wherein the Vpile yarn extends through the primary backing.
12. Pile carpet manufactured with the method as claimed in claim 2, comprising a perforated primary backing provided with an implanted loop-pile yam, wherein the looppile yarn extends through the primary backing.
13. Pile carpet as claimed in claim 11, wherein a secondary backing is arranged on the primary backing, wherein fixation parts of the V-pile yarn are located between the primary and the secondary backing.
14. Pile carpet as claimed in claim 13, wherein the fixation parts of the pile yarn are pressed between the primary backing and the secondary backing such that after pressing they have a flange form.
15. Device for manufacturing pile carpet or pile carpet tiles, comprising - a pile thread holder with a plurality of pile thread guide channels between a first side and a second side of the pile thread holder;
- a pile thread gripping station adapted to receive a primary backing on the second side and to arrange a pile thread from the first side through a pile thread guide channel through the primary backing provided on the second side; and - a press adapted to press a secondary backing against the primary backing while the pile yarn is situated through the primary backing and in the pile thread holder.
