ABSTRACT:
A continuous process for fabricating strips of gel-coated, self-adhesive bandages in which a laminate comprising a release paper strip fastened to a bandage strip whose lateral wound-side surfaces are coated with a pressure-sensitive adhesive is withdrawn from a feedstock roll and passed over a delamination roll where the two strips are separated. The release paper strip is then passed over an embossing roll where it is longitudinally scored, while a gel composition is simultaneously deposited on the middle portion of the bandage strip. The two strips are thereafter forwarded to a relamination roll at which point they are united in a relamination, and sent to a die-cutting roll where the desired bandage shape is cut into the bandage strip. The die-cut relaminate is thereafter forwarded to a delamination roll where the selvedge is removed, leaving a strip of the desired bandages.
