Embodiment 1

[0026] A rewinding / unwinding device for decomposing a bundle of filaments into parallel monofilaments, comprising a reed divider and a tension control device, the reed divider includes a divided reed 1, and the tension control device includes a reed / unwind frame 2 1. Creel 4, tension controller 5 and chain belt 3 arranged on the take-up / unwind frame, the rotating shaft of the creel 4 is connected with the rotating shaft of the tension controller 5 through the chain belt 3. The creel 4 is arranged in parallel with the dividing reed 1 .

Embodiment 2

[0028] A winding / unwinding method for decomposing bundles into parallel monofilaments, using the winding / unwinding device for decomposing bundles into parallel monofilaments in Embodiment 1, the method includes two processes of winding and unwinding. Specifically include the following steps:

[0029] 1) Adopt the front part of the production process of the cable wire, change the winding and forming step, and install the wire dividing reed 1 to decompose the bundle wire 7 into parallel monofilaments, and wind them in parallel on the special package bobbin 6;

[0030] 2) The tension is controlled by the tension control device, and the formed parallel monofilament on the special package bobbin 6 is unwound in parallel through the dividing reed 1,

[0031] 3) Using the winder in the production process of the split film yarn, the constant tension is used to wind and form monofilament; provide it to subsequent factories to process various monofilament fabrics.

[0032] The special ...

Abstract

The invention provides a coiling / uncoiling apparatus and its method for separating a bundle into parallel single filaments. The apparatus comprises a separator and a tension control apparatus, wherein the separator comprises a filament separating fastener, the tension control apparatus comprises a coiling / uncoiling rack, a drum rack disposed on the coiling / uncoiling rack and a tension controller, the drum rack fits with the tension controller by a shaft connection. The method comprises following steps: 1) employing the front end part of the cable rope filament production process, changing the coiling forming step, employing the filament separating fastener to separate the bundle into parallel single filaments and coil parallely onto special drums; 2) controlling the tension through the tension control apparatus, uncoiling the formed parallel single filaments on the special drums through the filament separating fastener; 3) employing the coiling machine for the split film filament production process to coil the single filaments with constant tension. The filaments produced with the invention have low costs and can satisfy the woven material production requires.

Description

technical field [0001] The invention relates to a method and equipment for decomposing filaments into parallel monofilaments and winding them separately, belonging to the technical field of textile fabrics for construction, geotechnical and hydraulic engineering. Background technique [0002] As a new type of material, monofilament support woven material has a wide range of uses due to its high strength, breathability and stable structure. It usually uses monofilaments made of synthetic resins such as PP, PE, HDPE or their mixtures to weave such products. The synthetic resin monofilament can change the cross-sectional shape in the direction of the fiber axis according to the purpose of use, from the most common circle to various shapes. Especially the synthetic resin monofilament used as industrial fabric raw silk, in order to meet the special requirements of diversified structures and different fabrics, not only the most common circular cross section, but also elliptical, ...
