Abstract: There is provided a male engaging member of a surface fastener comprising novel engaging elements that are flexible to a certain extent and highly durable and, at the same time, ensure a certain level of peeling resistance. The engaging elements of such an engaging member stably remain in engagement with piles of a female engaging member coupled with it without unintentionally becoming disengaged from the piles caught by them. The engaging miember comprises a flat substrate sheet, first engaging elements having a stem and an engaging portion disposed at the top thereof and second engaging elements having a column portion and a tilted hitch portion also disposed at the top thereof, the first engaging elements and the second engaging elements being arranged in linear rows independently relative to each other.

Abstract: A running length of fastener product is formed of longitudinally pre-oriented synthetic resin. The product is characterized by a base web and an array of discrete fastener elements protruding from at least one side of the web, the web being in a laterally stretched molecular oriented condition. After forming a preform having discrete fastener elements integral with a base web in a stretchable state, the preform is stretched in a manner that substantially increases the fastener element spacing and reduces the thickness of the base web. A machine is shown that is capable of lengthwise orienting before forming and widthwise stretching after forming, which employs controlled heating to render the product widthwise stretchable while preserving or achieving a desired shape of the fastener elements.
