ABSTRACT:
Apparatus for transversely adjusting a longitudinally moving strip of tire breaker building fabric is disclosed. In one embodiment, for adjusting vertically moving fabric, the apparatus comprises a frame including first and second pluralities of cylindrical rollers, the first and second pluralities of rollers being spaced apart to allow the fabric to pass therebetween, first and second transversely spaced rails mounted on the frame for transverse movement, first and second pluralities of cylindrical rollers supported by the respective rails contacting the respective side edges of the strip for transverse movement thereof, a rotatable shaft connected to the first and second rails by first and second link arms for simultaneously and equally moving the first and second rails transversely, and a counterweight connected to the shaft for rotating the shaft in a first direction to urge the rails toward one another and into contact with the side edges of the strip. In a second embodiment, for adjusting horizontally moving fabric, the apparatus comprises a frame including a plurality of universally rotating ball bearings for supporting the strip, first and second transversely spaced rails, first and second pluralities of cylindrical rollers, a rotatable shaft and first and second link arms, the rails, rollers, shaft and arms being similar to those disclosed with respect to the first embodiment, and first and second springs connected between the first and second link arms, respectively, and the frame for rotating the shaft in a first direction to urge the rails toward one another and into contact with the side edges of the strip.
This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.
