SU93495A1 - Compound needle circle for round combs - Google Patents

Description

The known composite needle wheels for combing machines are difficult to manufacture and require soldering to join their parts together.

The design of the composite circle of a series of concentrically arranged rings is simpler to manufacture and has the peculiarity that the rings on the outer and inner surfaces have recesses that form annular cavities in the assembled circle, into which stamped slots are placed to fix the needles.

FIG. 1 shows a cross sectional to the plane of the circle and a top view of the circle; in fig. 2 is a side view of a detail of a circle in FIG. one.

The inner part of the described composite needle circle, i.e. its body, is made in the form of a washer (1), having several rows of holes (2) arranged concentrically and intended for the collection of needles.

On its outer surface, the washer (1) has a recess between the booms (3), corresponding to

the shape and size of the undercut between the flanges (4) on the inner surface of the ring (5), covering the washer (1). The same grooves on the outer and inner on BfpxHocTH, located between the sides, is equipped with a ring (6). cover ring (5). Ring (7). the encircling ring (6) and the outside circumference of the entire composition of the HOii circle, has a recess between the sides only on its inner surface.

For the connection of the washer (1) and rings (5, 6, 7), stamped sockets (8) were used in a circle (Fig. 2), each of which is equal to half the thickness of the circle in height. The nest (8) is bent out of a metal plate like the letter P, the bridge between the side walls of the nest fits into the gap between the sides of the adjacent rings of the circle, and the sides (9) on the side walls of the nest hold the nest in the corresponding annular cavity between the rings.

Windows (10) are made in the cavity between the sides of the adjacent rings of the circle in order to fill the nests (8), the width of which slightly exceeds the width of the nest between its side walls.

Windows (10) are provided on both sides of the circle. As the ring circumferences fill the circle with nests, {§, ID: there are windows (1Q), M | a | schsch.

P) the invention

(A composite needle circle for circular combs, consisting of a series of concentrically) arranged rings, is distinguished by the fact that, in order to simplify the manufacture of circles, the rings on the outer and inner surfaces have annular recesses, forming circularly assembled cavities in which extruded sockets are placed to secure HI.l.
