Embodiment Construction

[0041] Figure 1a -f shows a schematic sequence of a method for tensioning warp threads, in particular flat plastic warp threads. A schematic view of a tensioning device 10 is shown, comprising a frame 11 and a tensioner 12, and which is perpendicular to the longitudinal direction of the tensioner 12 (longitudinal direction L, as in figure 2 with 4 as shown in ) is shown. The longitudinal direction of the tensioner 12 is substantially perpendicular to the extension of the warp threads 30 . The tensioner 12 is supported on the frame 11 and is designed in this example as a tensioning rod rotatably mounted relative to the frame 11 about an axis parallel to the longitudinal direction L. As shown in FIG. One or more joint strips 14 are attached to the surface of the tensioner 12 . Each engagement strip 14 is provided with a plurality of rigid penetrating needles 16 . The term "rigid" is defined as a material property of the piercing needle which is sufficient for piercing or p...

Abstract

The invention relates to a tensioning device. The device (10) has a framework (11), a clamp (18) which is adapted to the warp yarns (30) of a warp thread layer (35) to be fixed locally to the frame (11), tensioner (12) which used for tensioning the warp yarns (30) through the movement of the tensioner (12) relative to the framework (11) and is provided with plural penetration pins (16) formed along the longitudinal direction of the tensioner (12) along the surface of the tensioner (12). The penetration pins can be contact with the warp yarns (30). The ends of the penetration pins (16), far away from the surface orientation of the tensioner, are bent to form angles relative to the normal direction of the surface of the tensioner. The end parts of the of the penetration pins (16), contacted with the warp yarns (30), are oriented in a direction far from the clamp (18).

Description

technical field [0001] The invention relates to a tensioning device, a braiding machine, a closing machine and a method for tensioning a plurality of warp yarns. Background technique [0002] It is becoming more and more common to weave warp threads, for example flat plastic threads, into a textile material. Such woven materials thus obtained are used, for example, for containing, storing and / or for transporting food products, in particular vegetables. Another field of application can occur in all fields in which textile materials or webs with high strength and wear resistance are required, for example in agriculture. The flat plastic wire is made of polypropylene, for example. In order to weave warp threads or flat plastic threads into a woven material, the warp threads, usually wound on warp beams, are fed to the weaving machine and are wound one by one from the warp beam during weaving. [0003] It is known in textile technology to knot the warp threads of a nearly byp...
