Abstract
Abstract An oscillating guide roll assembly is illustrated for use with a cloth winder in building a cloth roll in such a manner as to avoid registry of the selvage portions throughout the build of the cloth roll. The subject oscillating guide roll is especially useful in connection with looms such as Sulzer looms having thickened edge portions which result from inserted filling ends in the selvage area.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
135 words
For use in a cloth winder having a driven cloth takeup roll, an assembly including an oscillating guide roll over which said cloth passes prior to the takeup roll comprising: a tubular roll member aligned transversely of the passage of a width of cloth in contact with the cloth as it comes to the winder; means mounting said tubular roll for rotation responsive to said contact with the cloth and for longitudinal sliding movement between said tubular roll and said mounting means; means driving said mounting means at a predetermined speed differential to and in the same direction of rotation of the tubular roll; and cam means between said tubular roll and said mounting means for imparting an oscillatory movement to said tubular roll relative to said mounting means in accordance with the speed differential.
Claim 2
Dependent Claim
