A method of forming a male touch fastener product with a resin surface and an array of spaced-apart male touch fastener elements carried on the surface. Each touch fastener element has a stem extending from the surface and a head disposed at a distal end of the stem and extending laterally from the stem to a distal edge overhanging the surface. The head, stem and surface form a contiguous mass of resin. The distal edge has multiple toes extending laterally outward and varying in shape and size about the edge, with adjacent toes having facing, free-form resin surfaces defining crevices therebetween. The fastener element is particularly flexible and engages with very fine fibers.

Making male touch fastener elements

A male touch fastener product has an array of discrete fastening elements extending from a resin base. The elements are formed by molding stems and then deforming at least a rim of a distal end of each head to form an overhanging mushroom-type fastener element. Some are deformed against a hard surface to form flat fastener elements, and others are deformed against a compliant surface and form umbrella-shaped fastener elements. The fastener element heads feature particular structural relationships that enhance their performance, particularly with low-lying fibers.

Male touch fastener elements

An elongated fastening strap of touch fastener material has a head with a grommet defining a slot through which the other end of the strap is received. Selective interference at the ends of the slot with the width of the strap alter the resistance to motion within the slot. The grommet provides a smooth surface within the slot.

Flexible fastening strap

A male touch fastener product with a resin surface and an array of spaced-apart male touch fastener elements carried on the surface. Each touch fastener element has a stem extending from the surface and a head disposed at a distal end of the stem and extending laterally from the stem to a distal edge overhanging the surface. The head, stem and surface form a contiguous mass of resin, the head. The distal edge has multiple toes extending laterally outward and varying in shape and size about the edge, with adjacent toes having facing, free-form resin surfaces defining crevices therebetween. The fastener element is particularly flexible and engages with very fine fibers.
