Title: High speed fluid treating, relaxing and thread advancing storage reel
IPC: D01D10/04
Filed: 1958-08-06
Abstract: A high-speed thread advancing and storing roller comprises a rotatable cylindrical cage formed by two sets of interdigitating bars arranged so that the diameter of the cage gradually decreases, and so that one set is stationary while the other is movable both vertically and towards and away from the axis of the cage, with means for introducing a liquid into the cage to contact the thread and means for removing the liquid adjacent the cage; as the cage revolves at high speed and one set of bars moves with respect to the other, the thread is advanced through the cage on the inside thereof in a series of helical turns in a relaxed condition.  As shown, the stationary set of bars 10 is integral with a rotatable housing 9 and a ring 19 which supports the movable set of bars 14, each of which has a cam-follower in inclined and eccentric races 15, 16 in a stationary housing 6. Each bar is wider at the bottom than the top so that the internal diameter of the cage gradually decreases.  The thread 2 enters the cage through a funnel 21 with the help of a jet of gas or liquid at 22, and <PICT:0848041/IV(a)/1> after leaving the apparatus passes over drying rollers such as 5. Treatment liquids including washing water are supplied respectively through two or more apertured tubes 24, 23 and are drained off from a corresponding number of troughs 28, 30.ALSO:<PICT:0848041/IV (c)/1> A high-speed thread &c. advancing and storing roller comprises a rotatable cylindrical cage formed by two sets of interdigitating bars arranged so that the diameter of the cage gradually decreases, and so that one set is stationary while the other is movable both vertically and towards and away from the axis of the cage, with means for introducing a liquid into the cage to contact the thread &c. and means for removing the liquid adjacent the cage; as the cage revolves at high speed and one set of bars moves with respect to the other, the thread &c. is advanced through the cage on the inside thereof in a series of helical turns in a relaxed condition.

Title: Improvements in or relating to the waterproofing of fabrics
Filed: 1937-09-24
Abstract: 496,902. Coated fabrics ; compound fabrics. SCHWARTZ, F. F., and CHAVANNES, M. A. Sept. 24, 1937, Nos. 26002, 26003, and 26004. Convention dates, May 14, June 23, and July 1. Drawings to Specification. [Class 140] Air-permeable waterproof fabric is made by spraying a closely woven or knitted inextensible fabric with rubber latex so that discrete globules are formed thereon which are coagulated and dried to form projections upon which subsequent latex deposits are formed by spraying as described in Specification 482,767. The size of the interstices of the coated fabric may be reduced by pressing as described in Specification 471,231. Suitable knitted fabrics are those which are inextensible due to their method of manufacture or due to stretching beyond their elastic limit. The fabric may be subjected to slight roughening, e.g. teaseling before spraying with latex. Water-repellent substances may be applied to the rubber-coated fabric as described in Specification 482,619. Compound fabrics may be formed by superposing the rubber-coated faces of two such fabrics, if desired, after subjecting the rubber to the action of a solvent vapour to render it adhesive, and pressing. The corresponding threads of the fabrics may be parallel or inclined at an angle. The fabrics may be pressed between two sheets of fabric to confer their pattern on the compound fabric. The example describes subjecting a closely woven cotton fabric to a light teaseling and spraying with rubber latex by means of the apparatus described in Specification 482,844. Two pieces of the treated fabric are united under pressure in a doubling calender, and the rolled-up compound fabric is exposed to the vapour of trichlorethylene to swell the rubber, after which the fabric is calendered and vulcanized by passage between heated cylinders. It is then lightly soaped, washed with a weak soap solution made alkaline by sodium carbonate, and rinsed with water. It may be further treated with a water-repellent material as described in Specification 482,619.
