Adhesive application with intermittent dead zones
Abstract:
A process is provided to create a strip of selectively pressure-sensitive adhesive material. A first roller unwinds a backing and a roller dispenses a series of separated areas of inhibited adhesive material. A second roller applies a continuous layer of adhesive material over the inhibited adhesive material and backing. A facing is applied over the continuous layer of adhesive material. The machine then winds the finished material. A removable backing is coated with non-sticky material and then covered by a continuous sticky layer of material. A face stock material is then applied over the continuous sticky layer.
