Abstract

In making air filters from continuously moving strip, hot melt adhesive is first applied to the edges, and the strips is then folded in accordeon manner to bring the adjacent coated strip edges into simultaneous contact. Pressure on the glued edges is maintained for a period while the strip is advanced on a conveyor, resulting in parallelepipedal pockets. Before adhesive application a set of rollers have provided the strip with transverse creases to aid folding and also with projection and recesses which prevent the pocket walls coming into close contact. The folded strip is cut into lengths with a pre-determined number of pockets, forming a filter unit which has its top enclosed in a frame to form a sealing flange. Pref. the adhesive is polyester-based. The appts. has relatively large output in a given period.
