Abstract
An apparatus for tensioning, stretching or pulling a traveling web of material (e.g., single or multiple layers) lateral to the longitudinal or machine direction of the traveling web is disclosed. The apparatus includes at least one but usually a pair of clamping devices to be disposed opposite each other on lateral edges of the traveling web upstream of a processing area where the clamping devices include stationary members, where at least one stationary member includes first and second ends and a material-engagement surface, wherein, when in operational position, the first and second ends define a direction of the material-engagement surface that is transverse to the machine direction of the traveling web. A method of stretching or pulling a single layer or multiple layer web of material laterally to the machine direction of the traveling web to remove wrinkles also is disclosed.
