1. A method of making a male touch fastener product, the method comprising
pressing moldable resin into respective molding cavities defined in a mold, thereby forming a resin layer on a surface of the mold while forming an array of spaced-apart resin projections extending from the resin layer;
stripping the formed resin layer from the surface of the mold, thereby pulling solidified resin from the cavities; and then
deforming distal ends of the projections by pressing the formed projections against a compliant outer surface of a heated roll, thereby forming from resin of each projection a fastener element comprising a stem extending from the resin layer to a head overhanging the resin layer.
