Abstract

A screen includes two or three layers (10, 12, 14) of woven metal screen cloth. The coarsest of these layers (12) includes threads (32) which are woven into the cloth with surfaces (26) which are fusible below a temperature at which the other layers of screen cloth are heat effected. These woven threads may include each of the threads in the coarse screen cloth with the coated threads being wire with fusible polypropylene or polyethylene coatings. The coarse screen cloth may include a woven metal screen with woven elements which are either coated with fusible material or are solidly of fusible material woven periodically therethrough in at least one direction. Screens are laminated with one or two fine mesh screens (10, 14) heated on the woven screen cloth with fusible surfaces to locate the fusible material in the finer cloths.
