ABSTRACT:
A method of fastening a button or the like to a garment such that the garment will be buttoned up after the fastening operation, wherein said button is composed of plastic and initially comprises a button head and a stem projecting from the button head, the stem having an outer end for piercing the garment and for deformation by ultrasonic vibration, a central section characterized by a substantially smooth profile, and an inner section flaring into the button head, the method comprising the steps of: providing a button hole in a first portion of the garment; placing said first garment portion in an overlying relation with a second portion of the garment; positioning said button such that the button head is disposed on the side of said first garment portion opposite to said second garment portion and such that the stem extends through the button hole and pierces at least partly through said second garment portion; and deforming the outer end of the stem by ultrasonic vibration thereof. A machine for practising the method is also disclosed.
