摘要

In a method of securing a plastics fastener stud 10 to a compressed fibre pad, an end portion 14 of the stud 10 is spun at high speed in contact with the pad while pressing the stud against the pad so that it penetrates into the fibrous mass. The end portion of the stud fuses and becomes bonded to the fibres to a substantial depth. The spinning is effected by inserting the stud in a rotary chuck of a high speed electric drill. The method is useful in attaching studs to trim pads for lining car doors.
