Methods for making fasteners

Abstract

A method for forming a fasteners is disclosed comprising providing a multiplicity of suitable polymer particles, providing a base with a front surface, and dispersing the particles onto at least one discrete area of the contact release surface, forming a predetermined shape. The dispersed particles are provided in a semiliquid state of a suitable viscosity, at least some of the particles in the discrete areas being in contact with the contact release surface for a time sufficient to transform into preform projections. The method further comprises conducting and fixing the front surface of the base with the terminal ends of at least some of the preform projections and removing the base from the contact release surface to separate the preform projections fixed thereto and form engaging projections projecting from the front surface of the base in the form of a predetermined shape.

1 . A method for forming a fastener comprising:
 providing a multiplicity of suitable polymer particles;   providing a base with a front surface;   dispersing onto a contact release surface a multiplicity of polymers particles in at least one discrete area of the contact release surface forming a predetermined shape;   providing the polymer particles, dispersed on the contact release surface, in a semiliquid state of a suitable viscosity, at least some of the particles in the discrete areas being in contact with the contact release surface for a time sufficient to transform into preform projections;   conducting and fixing the front surface of the base with the terminal ends of at least some of the preform projections;   removing the base from the contact release surface thereby separating the preform projections fixed thereto, thereby forming engaging projections projecting from the front surface of the base in the form of a predetermined shape.
