ABSTRACT:
Adhesive material is directed by two gumming applicators onto selected portions of a wrapping material as it advances in a given feed direction at a predetermined velocity, with no interruption in the movement of the wrapping material. The two applicators make a forward pass and a return pass, each composed of two constituent passes, during the course of which the adhesive material is deposited simultaneously along respective first and second segments of a first trail in the forward direction and in like manner along respective first and second segments of a second trail in the reverse direction; each complete trail extends transversely and substantially across the full width of the wrapping material.
