METHOD OF CHECKING FILLER CONNECTION PORTION Russian patent published in 2017 - IPC G01N21/95 B29D30/08 G01B11/02 

FIELD: physics.

SUBSTANCE: method of checking the filler connection portion, by which the connection state of both ends of the surfaces (531, 532) of the belt-shaped filler (53) that is fastened along the outer circumference of the bead core 52 is checked. The method of checking the filler connection portion includes the step of obtaining data on the distance between the optical sensors (33A, 33B) and the side surfaces of the filler (53) by scanning along the sides of the filler (53), the optical sensor sections (33A, 33B) of the adjacent region of both end surfaces (531, 532) along the tangential direction of the filler (53) in a predetermined scan range, the step of repeating the data acquisition step, when changing the positions of the optical sensors (33A, 33B) in the radial direction of the filler (53) and the step of comparing the obtained data with the control data, which are input in advance.

EFFECT: increasing the accuracy of checking the connected portion.
