DEVICE FOR COATING TAPE FEEDING Russian patent published in 2017 - IPC B29D30/48 

FIELD: transportation.

SUBSTANCE: device comprises a conveying element which performs reciprocating motions between the extended position and the retracted position while supporting the coating tape, and transports the coating tape onto the tyre board core surface. The guiding roller for directing the coating tape feeding is arranged with the possibility of rotation at a position farther from the tyre board core than the conveying element. The transmission mechanism converts the conveying element movement from the retracted position to the extended position into the guiding roller rotation in the direction of the coating tape feeding. Wherein the transmission mechanism is disposed between the drive element and the guiding roller and comprises a gear rack and a pinion. The rack moves together with the conveying element by means of the driving element. The pinion is connected to the guide roller and is engaged with the gear rack for rotation during the conveying element movement.

EFFECT: restriction of reducing the cover tape width, caused by the longitudinal extension of the coating tape during feeding to the tyre board core.
