Description

The invention relates to the basics - a raspberry bed with one row of slot needles, a knitter thread yarn bar, one row of platinum pile thread, one weft yarn feeder, several pile thread yarn guides that move inside the pitch in order to shape the needle thread guide, and with a guide comb raised, lowered and shifted between the thread yarns of the pile thread and the level of the needles, with the pile thread tracks formed by pairs of plates, which are closed from the end, and from the direction tracks, while the platinum pairs consist of a guide and a mortgage platinum,

The famous car (the GDR patent No. 140767, Cl. D 04 B 25/08), in which the platinum guide combs have a standard implementation, is known. They are made in the shape of an isosceles triangle, the base of which is facing the platinum pile thread. In the opposite direction of the withdrawal end there is a protrusion directed downward, t, e, towards the needle, which is aligned with the lower guide edge of the platinum, forming a mouth. The top edge of the guide comb is the diameter of the mill approximately parallel to the path of the pile thread yarn guide.

30 needle hooks level. Over each track there is a group of thread guides 5 pile threads with their pattern-forming thread guide 51 pile threads moving parallel to the groove lifting motion

The front edge of the platinum 2 pile thread and the remaining pile threads 54 form a throat, the top of which is a platinum thread guide involved in shifting the direction of the j-needles 1, the pattern-forming pile comb and laying the pattern thread 53 together with the nearby pile forming thread on the governing platinum guide comb immediately after selecting

The pile thread diagonally feeds - 0 Rogo is directed to the front edge with a thread guide, into the hook of the neighboring platinum 2 pile thread or to the place of its needle. In the next cycle in the undercut, in which the pattern-forming pile thread is laid on the initial needle, after shearing the guide comb In the opposite direction, the pattern-forming pile thread is laid under the hook of the needle with the embedded platinum of the guide comb. After the looping process is completed, the patterning mechanism formed by the two pile half loops is in the initial position. The new cycle begins.

However, in a known machine, when the yarn numbers are high and the large number of colors, the pattern forming pile is not relieved with the necessary reliability from pile threads. This is. The guide comb 6 is equipped with alternating guide plates 62 and embedded platinum

45 63, These platinum 62 and 63 in the level of the leading edge of the platinum 2 pile thread are located in the bar 61 and are placed vertically in the direction of the square. Platinum guides and inserts 62

50 and 63 alternately form the tufts 66 and the tracks 67, the tracks 66 are closed to the side and on the front side by the spacer 65,

A pile thread group 53 and 54 is supplied to each pile track 66. Guide tracks 67 are open at the needle level with the guide comb 6 lowered in a direction that leads to a failure in the pattern and a decrease in the quality of pile knitwear.

The purpose of the invention is the superior quality of the knitwear produced,

Fig 1 shows the place of formation. loops, cross section; Fig 2 is the same, top view; in FIG. 3, the same, the left thread supporter is absent, schematic right view; Fig. 4 shows the formation of the loops of Fig. 1, after raising and shifting the guide comb, a cross section; FIG. 5 is the same, top view; fig 6 is the same, right view; Fig. 7 is one embodiment of a guide comb;

Pile zalna machine design is made as a fable machine,

It contains horizontally positioned grooving needles 1, platinum 2 nap threads are placed at a right angle to them, at the needle level there are thread guides 3 knitting threads, which

perform a rolling and shearing movement, and a series of yarns 4 weft yarns located behind platinum 2 nap yarns, which are shifted about five steps and lowered under

needle hooks level. Over each track there is a group of thread guides 5 pile threads with their pattern-forming thread guide 51 pile threads moving parallel to the lifting motion of the groove

needles 1, pattern-forming pile thread 53 together with nearby located

The platinum front edge 2 of the pile yarn and the remaining pile yarn 54 forms the throat, the top of the needle 1, the pattern forming pile 53 along with the nearby

0 Rogo is directed to the front edge of the platinum 2 pile thread or to the place

out The guide comb 6 is equipped with alternating guide plates 62 and embedded platinum

45 63, These platinum 62 and 63 in the level of the leading edge of the platinum 2 pile thread are located in the bar 61 and are placed vertically in the direction of the square. Platinum guides and inserts 62

50 and 63 alternately form the tufts 66 and the tracks 67, the tracks 66 are closed to the side and on the front side by the spacer 65,

Each pile track 66 brings a group of pile threads 53 and 54, Guide tracks 67 are open at the needle level with the guide comb 6 lowered in the direction of extraction and allow the passage of the slot needles 1. In the front part of the guide tracks 67 there is a thread - feeder 7, which constantly takes part in the movement of the shear of the guide comb 6 and makes a separate vertical mortgage movement. The forward directed edge 73 of the guide appendage 72 with the selected pattern-forming pile thread 53 forms an open, preferably acute angle with respect to the thread guide thread 51 of the pile thread. The platinum guide 62 of the guide comb b contains, on top of the pile filaments 54, a guide edge 623 extending approximately parallel to the level of the needles and forms a pile with the protrusion openings and yarn guide 52

thread acute angle.

The front edge located on the front extends approximately parallel to the direction of movement of the pattern-forming yarn guide 51 of the pile thread. FIG. 7, it can go to a vertically directed needle level guide edge 68, which has the same function as the guide edge 73 of the thread guide 7. The lower edge of the platinum guide B2 at the point of the pile threads 54 has a throat 621, the width of which above the upper edge of the spacer 65, and the edge 622 of which is facing the spacer 65, extends vertically with respect to the y-shaped pile thread 53. This neck 621 prevents the pattern-forming pile 53 from being caught when the guide comb 6 is shifted by 1.5 sha ha of needles (fig. 4-6). She, therefore, cannot be located under the edge 71 of the thread feeder 7 (fig. 5). This occurs when the patterning pile 53 has not reached its normal position (fig 4)

Mounted and guided platinum with their free ends facing one side and V-shaped connected to each other ,. In this case, the lower edge of the embedded platinum 63 is parallel to the direction of pile threads 53,

The machine works as follows, 55 bodies 7, It lowers and runs the thread under the hook of a 12-slot needle 1, during the opening of the previous row,

The slot needles 1 of these both laid strings 31 and 53 form loops, and

loops the feeder 4 weft threads pads 1 weft threads into the slot needles. Slot needles 1, carried only

that the loops formed pass through the cutting path of the platinum pile thread forward. The guide comb 6 descends to such a level that the point of the protrusion of the pile threads 54 is located under the slot needles 1 to the left of the starting needle 1a (FIG. 3) in the path between the needles. In this position, the pattern-forming yarn filament 51 of the pile yarn moves Q forward and pulls the pattern-forming pile yarn 53 from the pile yarn 54 into the position shown in FIG. 1-3. Because of the notch 64, there is enough space for the rear pile thread 5 itself to be covered. The relatively high guide plate 62 protects adjacent tuft threads 54. Subsequently, the guide comb 6 rises below the level of the needles. The pile threads 54 between the guide comb 6 and the previous joint at the base weave move through the gap between the mortise needle 1 and the pile platinum 2. Meanwhile, the thread guide 7 rises, its protrusion creates the pattern of the pile thread 53.

The shifting of the guide comb 6 and the thread pusher 7 plevo (fig. 3) starts 1.5 steps from the initial needle 1a. The pile threads 54 are laid on the already fully raised slot needles 1 directly on the leading edge of the platinum pile threads ,. The yarn guide 3 of the knitting thread runs its knitting thread 31 onto the slot needle 1, the position shown in FIG. 4-.6 is reached. In this shift, the two guide edges 623, 73 and 68 are working, while the guide edge 623 on the guide plate 62 holds the pile threads 54 back together, the guide edge 73 of the thread 5 of the feeder 7 pulls the pattern forming milled thread 53 to spacer 65 in track 66 pile threads. Thus, there is an additional effect on the pattern-forming Q pile 53,

The patterning pile thread 53 is reliably released from the pile threads 54 and is fed diagonally under the embedded edge 71 of the thread under the thread.

the comb 6 is lowered to the right of the starting needle 1a; Knitted thread 31 is again shifted from the adjacent needle to the threading guide 51 of the pile thread; the tight pile thread 53 lies above the original needle 1a and under the fixed platinum 63. Further down the guide comb, the pile 53 enters the hook of the initial needle 1, and again on it is formed into a loop. As a result, two half loops of a pile thread are formed in two adjacent rows,
