Abstract

1472404 Reinforcing members made from filaments IMPERIAL CHEMICAL INDUSTRIES Ltd 15 Aug 1974 [22 Aug 1973] 39779/ 73 Heading D1T A reinforcing member for rubber or plastics articles comprises a plurality of man made continuous filaments the majority of which are surrounded and separated from adjacent filament for at least a major part of their length with elastomeric material, the filaments being grouped together in a predominantly parallel arrangement with some of the filaments or groups of filaments randomly overlying or mingling with the other filaments. The filaments may be of a polyester, a polyamide or glass. The elastomeric material may be a natural or synthetic rubber or a plasticised plastics material, for example plasticised polyvinyl chloride. The reinforcing member may be in sheet form or square, circular or rectangular in cross-section. According to one method the bundle of filaments is led through a fluid elastomer under low tension such that surface tension forces are able to separate the individual filaments and allow penetration of fluid elastomer, the filaments being sufficiently mobile for some individual filaments or groups of filaments to mingle with or move over other filaments. According to a second method the bundle of filaments is led under tension around one or more guide bars which serve to spread the filaments apart and prevent the bundle in separated condition to the fluid elastomer, the spread filaments then being passed in a low tension or tensionless condition into the fluid elastomer by way of tension stopping means such as a pair of nip rolls. According to a third embodiment the filaments are first randomly mingled by treatment in a turbulent gas stream and then treated with the fluid elastomer.
