ABSTRACT:
A device for connecting two layers of heat meltable material together comprises a toothed member which can be heated and pressed against a ribbed member with the layers of material therebetween. The toothed member includes three rows of teeth with gaps between adjacent teeth. Each row is separated by a gap thickness and the teeth have preferred widths. Thicknesses and lengths. The ribbed member has a pair of ribs that defines three grooves for receiving the three rows of teeth. Clearance is provided between the teeth and ribs while the teeth are bevelled to produce perforations in the heat meltable layers while firmly sealing the layers together around a periphery of each perforation.
