| 摘要 |
The invention relates to a method for manufacturing a breaker ply having a longitudinal axis, a breaker ply (12) length and mutually parallel cords at a pre-set cord angle to the longitudinal axis (A), wherein a continuous rubber strip (6) is provided with substantially parallel longitudinal cords, a set strip width and set centre-to-centre distance between the longitudinal cords one to the other, is produced in the longitudinal direction by means of a continuous extrusion process, the continuous rubber strip is cut into bands at the cord angle, a predetermined number of bands having cords substantially parallel to each other at a set band distance with respect to each other for forming a breaker ply having a (12) pre-set breaker ply length are placed on a support surface (10), wherein the mutual distance of the bands is calculated in order to realise a set length of the breaker ply, when the breaker ply has reached the target breaker ply length, the breaker ply is transported in the longitudinal direction to a building drum (15) and is wound onto the building drum, as well as a device for it.
