Zusammenfassung:There is provided a method of capping mechanical fasteners from a web having an array of upstanding stems. A heated surface member is positioned opposite a support forming a nip into which the web is fed. The heated surface member has a series of laterally spaced elongated peak and valley structures such that more than one peak and valley structure contacts and deforms each stem structure. The peak and valley groove structures provided asymmetric elongation and deformation of top portion of the stem structures forming hook heads.
