초록 ▼

The invention encompasses the pattern coating of a thick layer of adhesive on a single substrate. The adhesive strips may be continuous or discontinuouson the single substrate. In one preferred embodiment of the invention, the substrate is a release liner and the adhesive is a hot melt, thereby not requiring the use of an extruder in the application of the adhesive onto the substrate. When it is desired to produce a non-foamed product, the web is chilled on a chilled drum. Elimination of this chilling step, results in the formation of a foamed tape product, due to the evaporation of the moisture which is typically contained within the silicone-coated paper web. The product is a thick (10-100 mils), free (no carrier) film of adhesive made to the desired width (3/8" to approximately 6") of a high cohesive strength adhesive, with good temperature resistance (>196.degree. F.), with low bubble content (appears clear), wound into rolls containing from 100-800 feet or greater in length.

대표청구항 ▼

[ What is claimed is:] [1.] A process for pattern coating a plurality of strips of adhesive onto a release web comprising the steps of:feeding an adhesive into a feed manifold in a die assembly,the die assembly comprising:a die body having at least two exit ports in a front face of the die body; andat least two die cavity forming means, each of which receive adhesive exiting from at least one die body exit port, each die cavity forming means having at least one opening through which the adhesive can exit the die cavity forming means;passing a silicone-coated web under the openings of the die cavity forming means in the die assembly and depositing at least two non-contacting adhesive strips thereon;drying or curing the adhesive wherein the process of curing is selected from the group consisting of electron beam curing, ultraviolet curing and heat curing: and winding the adhesive coated web.
