The pulleys are mounted on a single shaft 31 provided with a handle and a ratchet mechanism. The winding mechanism of the base 5 is equipped with a parasitic sprocket 15, covered by a chain 19 and having the ability to move along the rack 17 of the bed 1.1 zp f-ly. 7 ill.

Description

The invention relates to textile production, namely to the manual manufacture of carpets, and relates to the construction of a loom.

Known manual carpet weaving machine containing the upper and lower shafts for the warp, the ends of which are placed in the uprights of the machine bed, the mechanism of winding the warp on the shafts having a gear, the sprockets of which are mounted on the shafts and are connected by a chain and the tension mechanism of the warp having a gear including a running gear a double-threaded screw connected with a manual drive and a nut pivotally connected to two pairs of at least one of which is connected to one of the shafts.

An object of the invention is to improve serviceability in the manufacture of long carpets.

In FIG. 1 shows a general view of the machine, a perspective view; in FIG. 2 - side view of the machine;

in FIG. 3 and 4 - the upper shaft of the machine with the clamping device; in FIG. 5 - tension mechanism, section II-II; in FIG. 6 and 7 - mobile seat of the machine.

The manual carpet weaving machine contains a bed 1, upper 2, lower 3 and additional 4 shafts, for the base 5. The axes of the upper 2 and lower 3 shafts are placed on the uprights 6 and 7 of the bed 1. The axes of the additional shaft 4 are placed in the guide bushings 8 and 9, covering guide rods 10 and 11, a base winding mechanism including sprockets 12,13 and mounted on the upper 2, lower 3 and additional 4 shafts, a tension sprocket 15 mounted on the sleeve 16 covering the guide rack 17 bed 1 and provided with a fixing clip 18 The sprockets 12, 13 and 14 and the sprocket sprocket 15 interact with the chain 19, the lower shaft 3 is provided with a handle 20. The mechanism of tensioning the base includes

cables 21 and 22, one end of which is connected respectively by guide bushings 8 and 9, and the other is wound on pulleys 23 and 24. Cases 25 and 26 of pulleys 23 and 24 by means of guide bushings 27 and 28 cover guide rods 10 and 11. Direction the sleeve bushings 27 and 28 are provided with fixing clips 29 and 30, the pulleys 23 and 24 are mounted on a common shaft 31 provided with a handle 32 and a ratchet including a gear wheel 33, a dog 34 with a handle 35 and a spring 36. The ratchet is located in the housing 25 with a pulley 23. The upper shaft 2 is equipped with a spring device including a rubber tube 37, prik eplennuyu to the presser jig 38, the ends of which are connected to the uprights 6 and 7 by a bolt 39 nut 40 with a special spring 41 .:

The machine is equipped with a height-adjustable seat 42, fixed together with the yarn table 43 on the base 44 of the trolley moving along rails 45 by means of rollers 46 connected by an axis 47. The rails 44 are connected by transverse links 48. The machine is equipped with a removable reed 49.

Hand carpet weaving machine operates as follows. For winding the warp 5, the beginning of the thread is passed over the shafts 2, 3 and 4, after which the beginning of the thread is knotted in a knot on the thread to form a triangle from the thread. By rotating the handle 20 on the shaft 3 by means of a chain 19 interacting with sprockets 12, 13 and 14, the shafts 2, 3 and 4 are rotated, which winding the thread on the shafts, forming the basis of the desired width. After winding the warp 5, the end of the thread is fixed on one of the shafts 2 or 3. The warp 5 is tensioned by rotating the handle 32, while the pulleys 23 and 24, mounted on the common shaft 31, wrap the cables 21 and 22, which move the guides bushings 8 and 9 along the guide rods 10 and 11 while moving the additional shaft 4. pulling the base 5.

The use of this invention will increase the length of the processed

carpet products, make the work of weavers more convenient, facilitate their work and increase productivity.
