Embodiment Construction

[0023] Figure 1 shows a module 1 in relation to a tufting machine, in which many such modules are used. These modules are mounted adjacent to each other to a bar extending in a transverse direction with respect to the direction of movement of the carpet to be manufactured, and preferably underneath said carpet. Furthermore, the tufting machine comprises a bar with tufting needles, one of these tufting needles 2 being shown in FIG. 1 . These needles are used to thread the pile yarn through the base fabric. This module is arranged to support the pile loops thus produced and to release them harmlessly, or to cut said pile loops as required.

[0024] The module 1 comprises a base body 3 having support surfaces 4, 5 for said bars. The holes 6 are used to mount the module 1 to the bar.

[0025] The modules are arranged on their side facing the base fabric (figure 1, top) with grooves 7, 8, 9 aligned parallel to one another and in this case respectively seated against said grooves...

Abstract

The device has a gripper with two gripper sections, where one of the gripper sections is provided for the production of looped pile and other gripper section is provided for the production of cut pile. The two gripper sections are located at a distance from each other in the direction of movement and are separated from each other by a step and by an extension. The gripper sections are configured as gripper edges that are parallel to each other. The gripper is associated with a guide, and gripper edges are aligned parallel to each other.

Description

technical field [0001] The invention relates to a clamping device for a tufting machine, in particular for the manufacture of carpets. Background technique [0002] The tufting method is often used in the manufacture of carpets. Referring to these tufting methods, a flat support material (so-called "backing") is arranged with pile. The pile consists of a large number of individual yarns which are passed through the base fabric row by row by tufting needles. In this way, the base fabric advances step by step under a row of needles, stitch by stitch. The loop of pile thus formed is temporarily supported by the clip in order to be held during the reverse stroke of the needle. Loop pile is formed if the pile loops remain undamaged. If the pile loops are cut, it forms cut pile. [0003] For the production of patterned structured carpets it is often desirable to use the same machine so as to be able to produce (possibly by enabling appropriate blades and grippers) uncut and c...
