DEVICE, OUTFIT AND METHOD OF PRODUCING TYRE BREAKER LAYER Russian patent published in 2008 - IPC B29D30/70 

FIELD: transportation.

SUBSTANCE: device features a lengthwise axis, a preset breaker layer length and parallel cord threads arranged at a preset angle of cord to the said lengthwise axis. The device also contains extruder for producing a continuous rubber band. The continuous rubber band is cut on tapes at cord angle. The preset quantity of bands with cord threads are parallel and pass at the preset interval relative to each other. Threads form a breaker layer with a preset length and are placed on the base surface. The general interval of bands is designed for making a preset length of the breaker layer. The said layer, the preset length formed, is moved lengthwise towards the assembly drum to be reeled up on it. The device contains the computing device with the memory unit storing an axes interval between lengthwise cord threads and lengths of the breaker layer, intended for calculation of the number of a tape, an interval of transfer from an axes interval, width of a band and the breaker layer length.

EFFECT: updated tyre and breaker layer production process.
