Problems solved by technology

However, during the swing of the guide tube, the warp yarn rubs against the inner wall of the tube, and this swing will cause obvious yarn wear
In addition, when the thread guide tube swings in a circular arc, the yarn tension drops significantly at the weaving point, which, in addition to a loose weave, also leads to an irregular and tangled weave pattern
The skipping of the shuttle through the gap additionally causes vibrations and fluctuations in the yarn tension
[0009] Consequently, the usability of this known circular loom is also disadvantageously limited

Embodiment Construction

[0128] The circular loom according to the invention according to figure 1 There is a centrally arranged core 1a, which has a cylindrical cross-section, and an annular rotating part (swivel) 2 . The core 1 a is mounted rotatably about a weaving axis 3 and displaceable along this weaving axis 3 on a hollow cylindrical housing 4 of the circular loom. The swivel 2 is likewise mounted rotatably on the housing 4 and rotates concentrically around the core 1a.

[0129] Fastened to the swivel 2 are two weaving shuttles 5 offset from one another by 180° and thus arranged opposite one another, which follow the circle formed by the swivel 2 at the same distance from each other due to the swivel movement of the swivel 2 The surrounding route (conveyor route) 2 is conveyed around the core 1a, and the conveyer route of the weaving shuttle 5 is determined by the configuration shape of the swivel (conveyor route). In this embodiment, the radial extension of the inner space of the swivel 2 de...

Abstract

The invention relates to a circular weaving machine for weaving a weaving core (1), comprising at least one shuttle (5) which has a weft spool (7) and can be moved along a circular continuous track around the weaving core (1), and warp coil devices (10), each of which having a warp yarn bobbin (11). It is proposed that the warp coil devices (10) are designed in a movable manner, wherein the travelpath of the warp coil device (10) with the warp yarn bobbin (11) extends through a weaving plane (6) which is enclosed by the circular continuous track (2, 23).

Description

technical field [0001] The invention relates to a circular loom for weaving a core, having at least one weaving shuttle with a weft bobbin and capable of moving around the core along a circular winding path, said circular loom also having a plurality of Warp yarn bobbins, each of which has a warp yarn bobbin. [0002] The invention also relates to a method for producing a hollow-profile fabric with a circular loom of the type described. Background technique [0003] Known circular looms and weaving methods for circular looms are generally used for producing hose-like fabrics for fire hoses, water hoses, bags and the like. [0004] A circular loom of this type is known, for example, from document EP 0080453 A2. A plurality of seats each have a weft bobbin (weft bobbin) which guides the weft thread on a circular track around the core, rolling along a circular revolving path on the upper and lower rolling loops. The weaving shuttle is driven by a motor-driven rotating member...
