SU436503A3 - HEAD OF THE GIVING DIGITS OF THE MOVING MACHINE - Google Patents

Description

The invention relates to the field of weaving.

The well-known head of the feeding machine rapier, in which the duck is inserted into the throat by forming a half-loop, one end of which is held and the other is free, consists of a hollow parallelepidoidal body, the horizontal walls of which are opp.

The disadvantage of this design is the large weft breakage when laying it in the ground: c.

In order to eliminate a weft break, a horizontal steak body shell is located on the side of the free end of the duck half eyelet. It has a bevel relative to the direction of movement, and a part of this machine, limited by the edge of the notch and the rear edge, forms a tongue located away from the adjacent vertical wall. The tongue is curved in the direction of the adjacent vertical wall, with its end located 1before and above its longitudinal edge, and the edge of the tongue from the side of the recess faces the pointed side of this wall.

FIG. 1 shows the proposed rapier head, side view, the free end of the half-weft of the weft yarn. It is in contact with the bottom wall of the head; in fig. 2 - the same, top view; pas figs. 3 is the free end of the half loop of the weft yarn at the moment of passage through the free gap, side view; in fig. 4 - the same, top view; in fig. 5 - head, front view; FIG. 6 - detailing the image of the resistant pads in an enlarged scale.

An insertion head is fixed on the sleeve 1. The head has upper and lower walls 2 and 3, two vertical walls 4 and 5, each of which is terminated from the input side with a pointed part, respectively 6 and 7. The latter is shifted back (in a known manner) and forms an extension to facilitate the entry of a hook Rapnry.

On the nutritional side, the wall is cut obliquely. The folded edge 8 extends from the vertical wall 4, to which the lower step is connected, n ends outside the vertical rail i5, with which the lower wall is not connected.

The part of the bottom wall that faces the inlet side is also obliquely cut off. The beveled edge 9 goes along the vertical wall 4 and is directed back to the edge 8 relative to the direction in Lenin of the displacement of the rapier. The edge 9 is interrupted by the edge 10, also beveled and directed in the same direction as the edge 8. The edge 10 forms with the edge 9 a protrusion continuing the pointed edge

part 6, and on the other oblique k.rom.koy 11, less

yakloinoi than terva, with respect to the direction of movement of the recess 12, in which we introduce.

The part of the bottom wall, bounded on the side of the food by the edge 8 and - of the notch 11, forms a tongue, the end 13 of which has a shanapa and ends somewhat higher and in front of the edge 14 of the vertical steak 5, thus leaving free (gap 15).

The bottom parts of the grooves are provided with lining 16 in the form of a half-bed 1ts, the outer contour of which is shorter than the bottom part of the notch, and its pointed ends 17 recede from the edges of this part of the notches.

The free end 18 of the weft half loop is pulled out on the ramp, indicated by the arrow 19, by hook of another rapier ("not shown), and the free end of the 20 thread is located on the head of the introductory rapier. The head of the rapier moves in the direction of arrow 21.

After transferring the weft loop from the introductory rapier K, which extends, the free ends 18 and 20 are for some time on the same Li and in the relative insertion head. When the return speed of the needle heads reaches a certain value, the free end, the speed of movement of which is double compared to the speed of movement of the heads, begins to oscillate. The end 20 is moved by irregular movement, leaps forward, at the moment of which the loops 22 are formed, falling from the feeding stalls into the head.

Subject invention

1. The head of the feeding chopper of the machine in which the weft is inserted into the throat by

forming a half loop, one end of which is held and the second I | Free; consisting of a hollow parallelepidic body, the horizontal walls of which contain grooves, characterized in that, in order to eliminate weft breakage, the edge of the horizontal wall of the head body, located with the sides of the free end of a half-weft duck have a bevel with respect to the direction of movement, with a part of this wall bounded by the edge of the notch and the rear edge forming a tongue located at a distance from the adjacent vertical wall .

2. The head of (P. 1, about the t and the fact that the tongue is bent in the direction of the adjacent

vertical wall, and its end is located in front of and above its longitudinal edge, and the edge of the tongue from the side of the notch facing the point of the pointed wall.
