METHOD FOR MANUFACTURING A REFASTENABLE MECHANICAL FASTENING SYSTEM AND FASTENING SYSTEM PRODUCED THEREFROM

摘要

The invention is a process for making a refastenable mechanical fastening system comprising the steps of providing a depositing member having at least one aperture having a diameter of between abou t 0.008 inch to about 0.040 inch; providing a molten thermally sensitive material having a storage modulus less than about 500 0 dynes/centimeter2 at the application temperature and a storage modulus of at least about 1 x 10 6 dynes/centimeter2 a t a temperature no more than 40 .degree.C less than the application temperature; providing a substrate; forcing the molten thermally sen sitive material through the aperture; depositing a discrete amount of the molten thermally sensitive material from the aperture onto the substrate; stretching a portion of the discrete amount of the molten thermally sensitive material in a direction having a vector component parallel to the plane of the substrate so as to form a prong; and solidifying the molten thermal ly sensitive material of the prong, the prong (22) having a base (26), a shank (28), and an engaging means (30), the engaging means (30) forming an included angle of at least 180.degree..
