Title: Improved manufacture of rubber thread and rubber thread textiles
IPC: B29D99/00
Filed: 1934-05-25
Abstract: Rubber thread is made by coating a textile thread with rubber, and subsequently removing this inner thread either wholly or in part. The removal may take place before or after weaving the threads into fabrics, and may be effected by dissolving out the inner thread, e.g. acetyl cellulose by acetone, or by carbonizing it.  The thread may be covered before removal of the inner thread with e.g. silk, cotton or artificial silk or with staple fibre dust.  The rubber coating composition may be from latex or rubber solution.  The Specification as open to inspection under Sect. 91 comprises also covering parts of the thread with a protective paste, as of gelatine, glue, or British gum, before treatment of the thread with a solvent, so as to obtain a thread partially unelastic and partially rubber elastic and also fabrics woven in part only of the rubber thread.  This subject-matter does not appear in the Specification as accepted.ALSO:Rubber thread is made by coating a textile thread with rubber, and subsequently removing this inner thread, either wholly or in part.

The bracket is connected to the beam 2 by independently controlled rams (20, 21). A free space 17 between the beam 1 and vertical wall 13 of the bracket 8 allows the latter, together with the end 3 of the conveyer, to move to the right in relation to the beam 1. The space 17 and a space 18 allow the beam 2 to be angled in relation to the general line of advance of the conveyer, e.g. when it is desired to tension the conveyer. Fig. 3 (not shown), illustrates the hydraulic arrangement for controlling the props (6) and the rams (19, 20, 21). It includes manual rotary valves (SV1, SV2), each incorporating a " deadmans handle." On being released the handle is raised by hydraulic pressure and the fluid ceases to flow. Isolating valves (Via, V1b, V2a, V2b) ensure that the props (6) remain set against the roof in the event of loss of fluid in the supply lines. Valves (V2C1, V2C2, V2D1, V2D2) ensure that each ram (20, 21) can be hydraulically locked, independent of the other. Further rams may interconnect the first beam or its associated slider bracket with a fixed abutment on the conveyer to tension the conveyer. Alternatively, the rams may be provided between the second beam and the conveyer.
