Abstract
This invention relates to devices for maintaining uniform the slack of a continuum of material while it is in process. One embodiment, particularly useful with machinery for wrapping tire-bead chafing strips, comprises an axle-mounted idler roll wherein the axle is supported by a pair of ball bushings mounted one each on support rods. The axes of the rods are parallel and variably inclineable so as to increase selectively the slope of the axes along which the ball bushings are impelled gravitationally, in opposition to the continuum of material as it is looped about and moves past or over the surface of the roll.
