ABSTRACT:
In gilling or stretching apparatus wherein a plurality of pin bars are driven and guided in a circuitous path including a stretching run and a return run, with threaded spindles engaging the pin bars along said runs, means are provided to retard the speed of movement of the pin bars before they engage the drive spindles so as to decrease noise in the operating apparatus and reduce wear of the pin bars and spindles. Such retarding means comprises cushioning wheels disposed at the entry end of the stretching run and cushioning rollers disposed at the exit end of the stretching run. The cushioning wheels and rollers have cushioning surfaces arranged to be engaged by the moving pin bars at an acute angle to the tangent to the surface at the point of engagement. Means are provided to insure that the cushioning wheels and rollers rotate at a slower speed than the speed of the travelling pin bars.
