Abstract

In a warp of injected plastic is anchored a thread guide ring (10) which may be made of case-hardened or stainless steel. The anchoring is effected by molding the plastic material of the warp about the ring (10). The ring (10) may have a substantially half moon-shaped profil, the edges thereof being sunk into the plastic material to insure a passage without catching. The elongated parts (22, 24) and/or the region (16) of the ring (10) have a substantially ovale cross section. Such a warp presents the advantages of a metallic warp with regards to the wear of the ring and the advantages of a non metallic warp with regards to its light weight.

The invention relates to textile machinery and relates to the design of the galey of a shedding mechanism of a weaving machine.

The looming shedding mechanism of a weaving machine is known, it contains an elongated plate cast from synthetic material with a hole in the expanded middle part and a thread eyelet mounted in the hole, the outer surface of which is made concave and the inner one is convex l.

. A disadvantage of the known Haleb is the high breakage of the main threads in the weaving process. The aim of the invention is to reduce the breakage of the main threads.

To this end, in a hay-hole, an immersed mechanism of the weaving machine. less than the height of the plate In the area of the hole, and the plate has annular projections covering the peephole from the side of its ends and smoothly mating with. its internal surface. .

In this case, the plate has an oval cross section.

In addition, the eye is made of cemented or stainless steel. . . . . Fig, i shows a halyovo with closed eyes MI at the ends, top view; in fig. 2 is a section A-A in FIG. one; FIG. 3 is a section BB in FIG. one; Fig. 4 shows a mold for the manufacture of a hale with an inserted eye, a cross section,. Talevo 1fig, 1) includes an elongated plate; 1, on the ends of which are the lugs 2 and 3 and the eye of the 4 for the thread, fixed in the middle thickened part 5 of the plate 1;

The peephole 4 has a longitudinal hole 8. The longitudinal sections 6 and 7 of the plate 1 have an oval cross section (Fig. 2).

The outer seating surface 9 of the peephole 4 is made concave, and its inner surface 10 is convex. Plate 1 has annular protrusions 11, covering the peephole 4 from the side of its ends and smoothly matching its internal noBepXHO –J stage 10.

The galevo-plastic composed of plastic is predominantly made by: casting with a pressure method, moreover, consisting of metal or even glass; the peephole 4 is filled with plastic. - Preferably hardened or stainless steel may be used as the metal. FIG. Figure 4 shows the preSF-form in section with an embedded eye 4. The mold has the lower half 12 and the upper half 13. The guide mandrel 14 is connected to the lower half of the mold 12, and the frame 13 connects to the upper half of the mold 13. 15 for placing and centering the eye. The ends of both mandrels 6 in the region of the eye serve to feed plastic into the mold.

; In the process of pouring, the edges of the semi-circular along the profile of the ends of the eye 4 are filled with plastic in order to obtain a layerless transition between the two materials. Compared to cheap,

. in plastic, the elasticity in its longitudinal direction favorably affects the weaving process, since the transition to any final one; the position of the hale during shedding occurs, is smoother and thereby preserves the main thread. Such plastic galevo is particularly well suited for combining with elastic devices for the observational movement of shafts in a weaving mill: jacquard fabrication.

 The cross section of the helium, which is oval in the area of shedding, creates a passage of the adjacent filament practically without friction,
