Description

A t {anforming device to shuttleless loom is known, including a reed, formed by a set of plates mounted on a shaft and provided with a weft sealing tooth and a lattice located under the warp yarns, consisting of sets of plates ensuring the passage of the bypass teeth and seals of the warp .

The proposed tissue-forming device is characterized in that in order to improve machine performance, a plate is inserted into the kit of the grate sheets, equipped with holes for passing and guiding the weft carrier, a hill supporting the fabric at the edge and a zuoi protruding above the warp threads and preventing the edge filaments from contracting weaving, as well as the fact that the reed plates can be mounted on the screw shaft of the rotating shaft, which ensures uniform distribution of the power of the weft thread in the work cycle NCA.

FIG. 1 shows the proposed device, side view in FIG. 2 is a front view of a part of the device.

The described device includes a reed 7, formed by a set of plates 2. mounted on the shaft 3 and provided with a tooth-compacted 4 Position about marked weft (weft thread). Under the thread 6 of the base there is a lattice (not shown in the drawing), consisting of sets of fixed plates 7, which allow the passage of the teeth of the baffle 4, reed / and the separation of the threads 6 of the base

A plate 8 is inserted into the grille of the lattice and provided with holes 9 for the weft carrier to pass 10, slide /// I support # 147548-2 the fabric 12 at the edge of the edge 13 and the tooth 14 protruding above the threads of the base 6 and preventing the edge filaments from contracting. weft 5.

Plates 2 Byrd 1 are mounted on a screw pinch nazu 15 of the rotating shaft 3, which ensures uniform distribution of the strength of the equipment 5 in the machine operation cycle.

The kits (sections) of the fixed plates 7 and 8 are mounted on a common base 16. The bar 17 serves as a link for the fixed plates.

The spacers 18 surround the movable plates 2 in the zone of action of the warp threads 6 in order to maintain a uniform distribution of the warp threads in the fabric. The lamellar 19 and round 20 gaskets provide a certain gap between the fixed plates 8 (the density of the fabric along the base) and the normal movement of the warp threads between the plates.

The separators 18 and the separator pad 21 form the necessary clearance for the free rotation of the movable plates 2 to the meladic plate 19 pads. After the laying of the weft yarn 5 into the shed of the main yarns 6, formed with the help of conventional shafts 22, weft carrier 10, weft thread from the hole 9 of the fixed plates 8 with the teeth 4 The movable plates 2 are moved along the slide 11 and are driven over the tooth 14, where the formation of the tissue takes place, which is then diverted through the chest 23 to the winding mechanism.

The weft yarn 5 is moved across the profile of the hill 11 of fixed ttlastin 8 and the fabric is formed successively across the width of the web, depending on the angle of the screw tongue and groove 15 on the shaft 5, on which the moving (surf) plates 2 are mounted.

The industrial usefulness of this proposal is confirmed by the All-Union Scientific Research Institute of Light and Textile Masynost, according to which the proposed tissue-forming device allows to ensure the production of high-quality fabric, which is confirmed by experimental work carried out on the TM-100 stand.

The process of tissue formation occurs with minimal impact of the movable plates on the warp threads. At the same time, thanks to the rotational movement of the movable plates and their arrangement in a spiral, the possibility of simultaneous and continuous nailing of several weft threads and, consequently, a significant increase in the productivity of the machine, is created.

The design of the proposed device is being developed at a designated institute for an experimental design of a TM2-120 weaving machine.

Subject invention

1. A fabric-forming device to shuttleless loom, including a reed, formed by a set of plates, planted on a shaft and equipped with a weft-sealing tooth, and a grating located under the warp threads, which provide for the passage of reed teeth-seals and the separation of warp threads , characterized in that, in order to increase the productivity of the machine, a plate is inserted in the set of lattice plates, provided with openings for passing and guiding the weft carrier, slide, supporting the fabric at the bottom and ubom protruding above the warp yarns and predotvraschayuschil1 astringent edge weft yarns substrate.
