Abstract

The device for transferring warp threads between the main shaft and the heddle on a textile machine for the production of multiaxial flat fabric has a ring placed between the main shaft and the heddle, which is either rotatably mounted, synchronously with the rotating main shaft and the feed of the healds in the heddle, or is provided with sliding elements along the inner circumference. The device for transferring warp threads between the main shaft and the heddle on a textile machine for the production of multiaxial flat fabric is usable in the textile industry, especially in the production of multiaxial flat fabric or in the laying of threads in the production of nonwoven fabrics.

Description

The invention relates to a device for transferring warp threads between a warp roll and a loom on a textile machine for the production of a multi-axis fabric, which serves to fuse the same free length of all warp threads.

In the production of fabrics, warp clamps are still used, which is a roller or dumbbell, which ensures the introduction of the warp threads from the warp roll into the weaving plane and at the same time serves as a sensor of the warp regulator or brake for warp thread tension. However, multi-axis fabrics cannot be produced on it.

Therefore, the device for transferring warp threads between the warp roll and the loom on a textile machine for the production of a multi-axis fabric according to the invention appears to be more perfect. Its essence lies in the fact that a ring is placed between the warp roller and the bridle, which ring is either rotatably mounted, synchronously with the rotary warp roller and the feed of the heddles in the bridle, or is provided with sliding elements along the inner circumference.

The device for transferring warp threads between the warp roll and the bridle on a textile machine for the production of a multi-axis fabric according to the invention makes it possible to produce a multi-axis fabric. It ensures a constant tension of all warp threads between the warp roll or tension rollers and the fabric during any rotation of the warp roll, because the warp roll rotates around the machine axis and not the bridle, because the heddles move in it. If it is necessary to maintain the same length of warp threads, a device which ensures this constant tension must be inserted into the warp. The transfer device forms a three-dimensional structure from the warp threads, where the warp threads leave it in a planar shape when unwinding from the warp roll, pass through tensioning rollers, sliding elements and enter the warp again in a planar shape.

The invention and its effects are explained in more detail in the description of an exemplary embodiment thereof with reference to the accompanying drawings, in which FIG. 1 is a front view and FIG. Fig. 5 is a front view and Fig. 4 is a plan view of a device for converting warp threads between a warp roll and a bridle on a textile machine for producing a multi-axis fabric with a fixed ring, and Fig. 5 shows a detail of sliding elements on a textile machine for the production of multi-axis fabrics.

The device for converting warp threads between the warp roll and the warp on a textile machine for the production of a multi-ply fabric according to the invention is placed on a textile machine for the production of multi-ply fabrics provided with a warp 4 and a warp roll 6 and serves to ensure a constant tension of all warp threads. from a ring £ which is either rotatably mounted between the warp roller £ and the bridle £ and synchronously with the rotary warp roller £ and the heddle passage in the bridle £, or is provided with sliding elements £ along the inner circumference.

The ring £ transfers the warp threads £ from the tension rollers of the warp roller £ to the bridle £ of the machine. The ring 6 also ensures their constant tension between the warp roller 6 or its tensioning rollers and the finished fabric during any rotation of the warp roller £, because the warp roller £ rotates about the machine axis and not the bridle 4, since the heddles slide therein. these warp threads £ are guided into the circumference of the ring £, which rotates synchronously with the rotation of the warp roller £ and the displacement of the heddles in the bridle 4.

In the design with the sliding elements £, the ring 2 converts the warp threads 3 from the warp rolls 6 to the loom 4 and again ensures their constant tension between the warp rolls 1 and the bridle 4 again with any rotation of the warp rolls 6, these warp threads £ being guided into elements 5, located on the inner circumference of the ring £ and moving synchronously with the rotation of the warp roll 1 and the movement of the heddles in the bridle £.

If it is necessary to maintain the same length of warp threads £, a device must be inserted into the warp to ensure this constant tension. The conversion device thus creates from the warp

260002 yarn 2 three-dimensional formation, where the warp threads 2 When unwinding from the warp roll 2, they leave it in a planar shape, pass through the tension rollers, the sliding elements 2 ^and enter the warp 2 again in a planar shape.

The device for converting warp threads in the production of multi-ply fabrics according to the lesion is useful in the textile industry, in particular in the production of multi-ply fabrics and / or in the laying of yarns in the production of nonwovens.
