Allan Wasserman ATTORNEY United States Patent 3,382,655 APPARATUS AND METHOD FOR MAKING METALLIC FRIEZE YARNS Allan Wasserman, 61 Wingate Road, Providence, RI. 02906 Filed Aug. 1, 1967, Ser. No. 657,601 7 Claims. (Cl. 57-16) ABSTRACT OF THE DISCLOSURE Apparatus and method for covering non-metallic core yarns with metallic cover yarns to form bright, scintillating frieze yarn suitable for making knitted or woven fabrics for garments and the like.

Background of the invention Frieze fabrics of the shaggy, rough textured type have been well known in the textile industry; such fabrics being formed primarily of wool yarns. More recently, frieze fabrics in knitted or woven form are derived in whole or in part from metallic yarns which give such fabrics a bright scintillating elfect and lend themselves to unlimited apparel designs.

The metallic yarns used in making frieze yarns are rather difiicult to combine with the usual non-metallic core .and cover yarns; and known procedures for making such yarns by twisting operations produce a relatively low output of high quality yarns.

Accordingly, an object of this invention is to provide improved apparatus and procedures for combining metallic and non-metallic yarn-s in a novel manner, to produce shag rough textured frieze yarns; the output of such apparatus being of uniformly high quality.

Another object of this invention is 'to provide improved apparatus of the character described, which can be operated at high speeds to produce metallic frieze yarns at rapid production rates; the product being of uniform high quality.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

Summary of the invention The instant invention relates to improved apparatus for applying metallic and non'metallic cover yarns to a non-metallic core yarn at high rates of speed and in a manner to associate the several yarns to produce a high quality frieze effect.

Brief description of the drawing The single figure of the drawing is 'a schematic view of an apparatus embodying the invention for making frieze yarn.

Description of the preferred embodiment Metallic frieze yarns comprise a core yarn of nonmetallic material such as rayon or the like; the core yarn being covered with 'a selected metallic yarn which is wound around the core yarn in one direction, the metallic yarn being locked in place by a cover yarn of non-metallic material such as rayon or the like, which is wound over the metallic yarn in the opposite direction.

In order to obtain a commercially acceptable frieze yarn, the metallic yarn must be wound about the core yarn in a manner such that portions thereof project laterally of the core yarn to produce the desired shaggy, rough textured effect.

Accordingly, as shown in the drawing, 10 designates a spool of core yarn 11 which is loosely supported on a base 12. Core yarn 11 may be rayon with a 75 to 900 3,382,655 Patented May 14, 1968 denier and of the multifilament type with a twist of 2 to 3 turns per inch. The core yarn 11 moves upwardly from spool 10 through a guide eyelet 13 extending from a guide support 14; and thence passes about a star wheel 15 rotating on a horizontal shaft 16.

The upwardly moving core yarn 11 is wrapped with metallic yarn 17 taken from a spool 18 which is mounted on a tubular spindle 19 arranged for rotation about its vertical axis by way of belt means 20 passing about whirl portion 21 of the spindle 19. The metallic yarn 17 feeds freely from spool 18 as the same is rotated, with a ballooning effect, and is wrapped about upwardly moving core yarn 11 above spindle 19.

The metallic covered core yarn continues its upward movement through a rotating tubular spindle 22 which carries a spool 26 of cover yarn 24 which may be rayon or the like. Cover yarn 24 passes from rotating spool 23 through a flier 25 mounted on the spool 23 in a conventional manner; the flier 25 being of known construction, as shown in Patent No. 1,826,713.

The spindle 22 is rotated by means of belt 20A passing about whirl portioin 26 of the spindle, in a direction o-pposite to that in which spindle 19 is rotated. Thus, the cover yarn 24 is effective to lock the metallic yarn 17 in place on core yarn-1'1.

The resultant frieze yarn 27 moves upwardly above rotating spindle 22, passes about a star wheel 28 rotating on a horizontal shaft 29 and 'thence to a takeup roll 30 rotating on a horizontal shaft 31.

It has been found that with metallic yarn '17 freely fed from its spool 18 and applied to core yarn 11; cover yarn 24 being applied by way of flier 25; and the speeds of the spindles 19, 22 and takeup roll 30 suitably correlated the resultant frieze yarn 27 will be of uniform high quality.

The spindle 19 may be rotated through its belt means 20 at speeds ranging from about 2500 to about 3200 r.p.m., with a preferred speed of about 2900 r.p.m. The spindle 22 may be rotated at speeds ranging from about 4500 to about 5300 r.p.m., with a preferred speed of about 5000 r.p.m. The takeup roll 30 is rotated at a speed of from about 30 to about 45 r.p.m., with a preferred speed of about 36 r.p.m. The star wheels 15, 28 are rotated at suitable speeds to maintain the upward movement of the core yarn 11 and associated yarns 17, 24 in a properly tensioned condition.

The metallic yarn 17 is of conventional type with a width ranging from $6 inch to about inch, with a width of inch being particularly effective. The cover yarn 24 is a multiiilament yarn of rayon, nylon, polyester or the like and may have 'a denier of from 70 to about 300.

It is understood that spindles 19 and 22 are rotated by suitable motor means, not shown, through belts 20, 20 A;

and takeup roll 30 is also rotated by motor means, not.

shown. The speeds of such motor means is suitably regulated to obtain the spindle and takeup roll speeds as in-,

dicated above.

As various changes might be made in the herein disclosed embodiment of the invention without departing from the spirit thereof, it is understood that all matter herein shown or described shall be deemed illustrative and not by way of limitation except as set forth in the appended claims.
