Apparatus and technique for monitoring component position during tire building

摘要

A system and technique for monitoring the positions of the lateral edges of tire components during a tire building operation. Fluorescent lamps are positioned on opposite sides of the tire building drum to orthogonally impinge light onto the vertical cut edges of the tire components. The cut ply cords exposed at these vertical edges reflect the light to a camera having a portion of the tire building drum and the ply laminate within its field of view. The camera is controlled to obtain pairs of data windows, one on each side of the belt laminate, at fixed and spaced intervals along the circumference of the laminate. A mosaic is then generated from these data windows to illustrate the amount of walking, snaking, or centering of the tire building components during the manufacturing process.
