Abstract: A method of forming a touch fastener product having a sheet-form base and an array of discrete fastener elements each extending from the base includes providing a molded sheet-form base and an array of discrete fastener element preforms, each preform extending from the base and including both a stem portion rising from the base and a head portion both contiguous with a distal end of the stem portion and having an upper surface directed away from the base, the head portion including at least one laterally directed extension overhanging the base in a primary lateral direction between exposed sides of the fastener element preform and ending at a distal, free tip; and then forming respective caps, of a cap material of a higher flex modulus than the resin of the preforms, on the upper surfaces of at least some of the molded fastener element preforms to form the discrete fastener elements.
