ABSTRACT:
This invention pertains to a spreader roll adapted to remove wrinkles, ripples, bags and torque marks from fast-traveling webs of material of fabric, plastic or combinations thereof. The resulting fast-traveling web has a smooth, uninterrupted surface. This spreader roll is not a bowed or grooved roll, but is a straight roll having a resilient outer tubular rubber sleeve. The supporting shaft is straight, rigid, non-rotating, and is carried by support blocks. This outer sleeve is retained at each end by clamp means which is carried by anti-friction bearings. This clamp means includes a bearing ring which is pivotally carried by the central shaft. Each pivoted bearing ring is individually adjusted to stretch the resilient cover to remove the distorting wrinkles, ripples, bags or torque marks in the fast-moving web. A multiplicity of disc brushes is carried on a freely rotating tubular member and these brushes are positioned by spacer rings. The brushes accommodate the expansion and contraction of the resilient outer rubber sleeve.
