ABSTRACT:
A continuous method of manufacturing a plurality of sheet material blanks each having a surface uniformly coated with a tacky layer comprises passing a long length of the sheet material through a first station in which tapes are applied to a surface of the sheet material transversely to the direction of movement of the sheet material and at longitudinally spaced-apart locations, at a second station applying a continuous layer of tacky material to the surface of the sheet material and over the tapes so that tapes mask portions of the surface, at a third station removing the tapes to leave transverse regions free of tacky material and then cutting the sheet material in the regions which are free of tacky material to thereby produce a plurality of sheet material blanks.
