ABSTRACT:
A decorative member such as a welt or a button attached to a surface layer of a seat cushion, and a method and apparatus for forming such a decorative member are disclosed. In the method and apparatus, an upper plate is disposed for vertical movement relative to a lower plate, and a pair of holding members defining an insertion space between their upper end portions are vertically or horizontally movably mounted on the lower plate. A covering and a core providing the decorative member are inserted in the insertion space, and a seat cushion is placed between the upper and lower plates with its surface layer facing the holding members. The upper plate is urged downward toward the lower plate to compress the seat cushion onto the holding members while, at the same time, enclosing the core in the covering in the cooperation with the holding members. High frequency current is supplied to complete the decorative member and to weld it to the surface layer of the seat cushion.
