Description

Known flat dressing machines for making artificial fur in the form of a pile cloth from unpaved to pile threads are equipped with two needle cases with movable tongue needles in one and needles without heads in the other, on which they form thieves; ivy loops imitating the hair of natural fur, and movable along the needle cases of the lock carriage with yarn feeders for dirt and pile threads.

These machines cause a pile cloth with uncut loops; cutting the latter is done by shearing the pile on a shearing machine, which increases the labor intensity of production and the consumption of pile threads, some of which go to waste when shearing the pile.

The described flat machine eliminates the noted drawbacks in that the cutting of the pile loops is carried out when making a pile, for which hook needles are used at one of the machine’s needles, for example the front, to pull off the pile loops, and two knives that cut the pile are fixed on the carriage loops in both directions of carriage movement.

FIG. Figure 1 shows the structural pattern of the interlacing of the produced pile knitted fabric; in fig. 2 - trajectories of movement of the heads and the current of the tongues and hook needles; in fig. 3-yarn feeder, side view of the machine; in fig. 4 - the same, end view of the machine; in fig. 5 shows the moment of the capture and bending by the hook needles of the pile thread and in FIG. 6-locking carriage, top view.

In one of the two needles of the flat-bolstering machine, for example, the rear, ordinary tongue needles 1 (FIG. 2 and 5) are installed, and in the other, for example, the front ones, hook needles 2 are used to pull the pile loops 5 (FIG. 1 and 5) out of the pile thread 4. Reed needles / and their locks 5 (Fig. 6) occupy the usual position relative to line 6 (Fig. 2 and 5)

N ° 121210

the rear of the needle bar is taken away, and the front needle bed locks 7 are centered down from the front needle bar's line 8 by the length of the nap loops produced.

For the possibility of hooking with hook needles 2 of the earth thread 9 (Fig. 1), these needles are respectively shortened and their heads are raised by a smaller amount relative to line 8 (Figs. 2 and 5) from the front needle case compared to the heads of the needle needles. FIG. 2 depicts the trajectories of 10 heads of the needles, the trajectory // path of these needles, the trajectory of 12 heads of hook needles and the trajectory 13 of the needles of these needles. The ground and pile threads are laid by a common yarn feeder 14 (Figs. 3 and 4), equipped with two openings 15 for these threads. In order to cut the pile loops, two blades 17 are fastened to the carriage by means of brackets 16 (Fig. 6), cutting the loops 3 removed by hook needles 2 in both directions of movement of this carriage.

The production of the nap web is carried out as follows: The crochet web is harvested from a ground 9 and a nap 4 threads in such a way that one of the needle beds, for example back, with tongue needles 1, stitches the soil and pile, and the other igloo, for example, with hooked needles the needles 2 draw off the loops 5 of the pile thread, and then cut these loops with one of the two carriage knives 17, depending on the direction of its movement.

In order to obtain a shakhmatous placement of the pile loops or their patterned placement, the hook needles are placed through one tongue needle or in another order and alternate shift of the needles is carried out in view.

Subject invention

A flat machine for producing artificial fur in the form of a pile cloth, equipped with two needle beds with movable tongue needles and a movable locking carriage with yarn feeders, characterized in that hooks were used to ensure the cutting of pile loops on one of the needle beds, for example, front ones. needles for pulling loose loops, and on the carriage two knives are fixed, cutting nap loops in both directions of carriage movement.
