发明名称 Absorbent pad and method for making same
摘要 An elongate, disposable absorbent pad having an elongate, absorbent, fluff batt of cellulosic fibers enclosed within a fibrous envelope having a fluid pervious facing layer and a backing layer. The fibrous envelope has end margins which extend beyond end margins of the fluff batt, and the end margins of the fibrous envelope are closed by transverse end seal bands having seal rows with opposed surfaces defined by transversely adjacent ridges and valleys interconnected by lateral walls. The lateral walls of the seal rows are compressed to define seal regions characterized by interlocked fibers of the envelope; said seal regions, in the plane of the absorbent pad, extending in the direction of elongation of the absorbent pad. The method for continuously manufacturing elongate, disposable absorbent pads having end margins which are closed by transverse end seal bands as described above forms a part of the present invention.
