ABSTRACT:
A web of jacketing material is unwound from a reservoir thereof and conveyed at constant speed. A double sided, pressure-sensitive adhesive strip, having one side protected by a removable sheet covering, conveyed in a direction normal to that of the jacketing material, is cut to predetermined lengths, positioned subjacent to and then applied across the width of the jacketing material at predetermined intervals. The jacketing material is sheared into sections by making cuts across the material along the middle of the adhesive strip and at a line midway between adhesive strips.
