ABSTRACT:
Silk screen roller applicators, employed in a process which is also known as Screen Process Printing, are often used in the printing of labels and other materials. The present invention involves joining the edges of silk screen type material along a very narrow line, such as 1/32 inch, so that economies are achieved in printing and the associated use of paper, when the resultant applicator is formed. The two edges to be joined are each marked with at least two index marks, and these are aligned with corresponding light slots which are located on a base on either side of a fusing line. The silk screen type mesh which may be formed of a polyester coated with nickel, may be held down by magnetic plates, and the edges are accurately overlapped by aligning the index marks and the light guide slots, through the use of eccentric or similar mechanisms. A thin thread of nylon or other fusible material is tightly drawn between the edges of the fabric along the fusing line, with the fabric overlapped by about 1/32 inch. A pre-heated fusing bar is briefly lowered along the fusing line and promptly raised, after fusing the thread into the pores in both of the two edges of the silk screen type material.
