A method for making a hot melt adhesive bonded pile fabric which comprises: positioning two continuous, liquid-permeable base layers in a passage where they lie in substantial parallel relationship to one another at a predetermined distance from one another; driving at least one continuous pile form

A method for making a hot melt adhesive bonded pile fabric which comprises: positioning two continuous, liquid-permeable base layers in a passage where they lie in substantial parallel relationship to one another at a predetermined distance from one another; driving at least one continuous pile forming yarn by folder blades alternatively against the opposing surfaces of said base layers when they are at or near the entrance to the above mentioned passage in such a way as to position the pile forming yarn relative to the base layers and to fold it zig-zag without tufting said pile-forming yarns through said base layers; thereafter applying to the back of said base layers a hot melt adhesive; forcing said hot melt adhesive through said base layers so that said hot melt adhesive contacts said pile forming yarn; cooling said hot melt adhesive to a temperature below its softening point to thereby bond said pile forming yarn to said base layers; and cutting said pile forming yarns to form two continuous hot melt adhesive bonded products.
