ABSTRACT:
An apparatus which guides tire tread strip material toward a tire-building drum and maintains the strip centered by compensating for minor variations in strip width. A pair of guide rails are adjustably mounted on a support housing and contain strip-engaging rollers which form a guide path for the tread strip therebetween. A panograph linkage is mounted on the housing and connects the guide rails for simultaneous movement of the rails toward and away from each other. A biasing mechanism, such as a spring or weight, biases the rails toward each other and the rollers into guiding engagement with the edges of the tread strip, and enables the guide rails to automatically move inward or outward to compensate for variations in tread width. The guide rails are freely movably mounted on spaced bearing rods for transverse adjustment with respect to the travel of the tread strip. The guide rails may be individually pivotally mounted on support brackets to adjust the angle of contact of the guide rollers with a tread strip.
