ABSTRACT:
An apparatus and method in which lengths of web material joined by widthwise seams are guided along a path of travel adjacent a shear, either for decorative shearing or for roll winding. In the instance of decorative shearing, the web material surface is sheared to produce a particular desired effect, such as velour fabric. In winding, web material is wound into a roll of up to a first diameter at a starting winding position and then transferred to a second winding position at which winding continues to a larger diameter. The web material is controllably sheared or severed between the starting and second winding positions upon the material roll being wound at the second position reaching a desired diameter. In accordance with this invention, a plurality of seam detectors are provided and shear movement occurs in response to and in predetermined relation with sensing of a seam by all of the detectors, in order to avoid severing a seam in decorative shearing or to sever through a seam in winding.
