Transfer roll system

Apparatus for transferring strip components from a conveyor to a tire building drum member comprising a supporting structure, a swinging arm member pivotally mounted on said supporting structure, a pair of transfer rolls mounted on said swinging arm member in spaced-apart relation for rotation about a single axis, said swinging arm member including pivot means connected to said supporting structure for swinging of said swinging arm member from a conveyor position with said pair of transfer rolls in engagement with said conveyor for receiving said strip components at a conveyor spacing to an application position with said transfer rolls in engagement with said tire building drum member for applying said strip components to said tire building drum member at a tire spacing different from said conveyor spacing and to an intermediate position with said transfer rolls located between and spaced from said conveyor position and said application position, and means not connected to said conveyor to move said transfer rolls axially along said single axis in said intermediate position to adjust the spacing of said transfer rolls to said tire spacing at a point in the course of swinging of said swinging arm member from said conveyor to said tire building drum member for application of said strip components to said tire building drum member at said tire spacing and adjust said transfer rolls to conveyor spacing at a point in the course of swinging of said swinging arm member from said tire building drum member to said conveyor for receiving said strip components from said conveyor without requiring adjustment of said conveyor to said tire spacing including a stop member mounted on said supporting structure and engageable with said swinging arm member in said application position for supporting the weight of said arm member, each of said transfer rolls having a hub member mounted on a shaft coaxial with said single axis, an outer rim member spaced radially from said hub member and movable relative to said hub member toward said tire building drum member in said application position for engagement of said outer rim member with said tire building drum member and pressure means for urging said outer rim member against said tire building drum member at a predetermined pressure, said stop member being mounted on said supporting structure such that none of the weight of said swinging arm member in said application position is pressed against said strip components and said tire building drum member prior to movement of said outer rim member against said tire building drum member.
