Abstract
Apparatus for manufacturing tire breaker fabric comprising a cord feed unit, guide means for guiding a single cord between two sets of retaining means attached one to either edge of an endless belt to form an elongate sheet of parallel closely spaced cords laid in zig-zag fashion such that the edges of the sheet are formed by a series of folded cord edges which are held by the retaining means. Stepwise drive means advances the belt and cord assembly to elastomer applying means for applying elastomer to one surface of the cord assembly.
Claims19
Apparatus for making a tire breaker fabric comprising an elongate sheet of tire cord fabric embedded in elastomer in which the cords extending across the sheet are formed by one single continuous tire cord which extends back and forth across the sheet so that the edges of the sheet are formed by a series of folded cord edges, the apparatus comprising:
- (a) a pair of parallel spaced-apart retaining means;
- (b) each retaining means comprising a plurality of longitudinally spaced fixed pegs attached to endless belt means;
- (c) a feed unit for one single continuous tire cord;
- (d) guide means for guiding said tire cord to and fro between said retaining means;
- (e) said guide means being shaped to impart a fold to the tire cord at each retaining means to form a continuous elongate cord assembly the edges of which are formed by a series of folded cord edges;
- (f) respective clip means associated with each retaining means to receive and transfer each folded cord edge to a respective peg of the associated retaining means;
- (g) stepwise drive means to move said endless belt means in the direction of its length;
- (h) means for applying elastomer to said cord assembly to produce tire breaker fabric;
- and
- (i) means for removing said retaining means from said tire breaker fabric.
