Abstract

Abstract A tape applicator for applying transversely extending strips of adhesive tape at predetermined intervals along the edge of a moving web of material such as disposable diaper stock, and for simultaneously applying release coated covered tabs over the strips of tape. The tape applicator may utilize either wide tape cut into short segments or, with an appropriate change of gear ratios, may use narrow tape cut in long segments to take advantage of the longitudinal strength properties of certain types of tape material. In the latter case, the long narrow tape segments are re-oriented and applied to extend transversely from the edge of the web material.
