First and second complementary snap-fastener components locally and in-situ molded to the same side of a single flexible porous substrate and at relatively short spacing from each other, such that the substrate can be folded between these complementary components to permit their selective mutual engagement and disengagement. One of these formations is a stud component and the other is a socket component, and the sizing of their engageable formations is such that a predetermined clearance characterizes a loose fit when in mutually engaged relation. The looseness of this fit bears a predetermined relation to the thickness and flexible deformability of another flexible member or tie element which is interposed between the snap-fastener elements to secure a given selected location of snap-fastener retention to the tie element. Several embodiments are described.
As an article of manufacture, a first porous substrate portion of unapertured flexible material having spaced first and second complementary snap-fastener components each of which is formed from a single charge of plastic material locally and in-situ molded to the same side of said substrate portion, said components being a socket component and a stud component which are sized for loose engageability to each other upon flexed folded manipulation of the material between said components, said engageability being characterized by a predetermined clearance relation between said components when in engaged relation;
As an article of manufacture, first substrate portions of unapertured flexible material comprising two like rectangular pieces of length at least twice their width, first and second complementary snap-fastener components each of which is formed from a single charge of plastic material locally and in-situ molded to one side and near one end of a different one of said two pieces, said components being a socket component and a stud component which are sized for loose engageability to each other, said engageability being characterized by a predetermined clearance relation between said components when in engaged relation, and a fabric mounting to which the other end of each of said pieces is independently secured, in such orientation that said snap-fastener components are in confronting registration.
