Abstract:
1. A carcass ply producing method for producing a carcass ply constituting a carcass layer of a tire comprising: supplying at least one ply cord by a supply head, reciprocating said supply head along a widthwise direction of said carcass ply, sticking said ply cord supplied by said supply head to a sticking body having a sticking surface, reciprocating said sticking surface of said sticking body to move the sticking surface (i) in either the forward or backward direction along a longitudinal direction of said carcass ply, then (ii) forward at a pitch to arrange said at least one ply cord in substantially parallel lines on the sticking surface, and finally (iii) in the opposite of the previous forward or backward direction alone the longitudinal direction of the carcass ply, wherein one widthwise reciprocating motion of said supply head occurs while one longitudinal reciprocating motion of (i) or (iii) of said sticking surface occurs, and controlling a disposition angle of said ply cord with respect to said longitudinal direction by changing a moving amount of said sticking surface with respect to a moving amount of said supply head.
