For this reason, the part pressed by the side jaw 70 of the core string R is arranged in a straight line shape (a state having no irregularities along the length direction of the fastener chain C) so as to rise upward.

Note that the shape in which the core string R rises upward means that the outer surface of the core string R is pressed by the side jaws 70, whereby the width dimension (the horizontal dimension in FIG. 10) of the core string R is reduced. In addition, the height of the core string R (the vertical dimension in FIG. 10) is increased. In this embodiment, the core string R is changed from a substantially rectangular shape as shown in FIG.

As a result, the fastener element E at the upstream end of the space portion S of the fastener chain C comes into contact with the first stopper 40, and the space portion S of the fastener chain C stops at a predetermined position. The conveyance of C is stopped.

Next, as shown in FIG. 11, the second stopper 50 moves upward to project into the space S from below, and the pressing rod 62 of the chain pressing device 60 moves downward to press the fastener chain C downward. As a result, the fastener element E at the downstream end of the space portion S of the fastener chain C comes into contact with the second stopper 50, and the movement of the fastener chain C to the upstream side is restricted, and the slack of the fastener chain C is removed. Is done.

By pressing the outer surface of the string R toward the first stopper 40, the portions pressed by the side jaws 70 of the left and right core strings R are straightened with a cross-sectional shape that rises upward.

Next, as shown in FIGS. 13 and 14, when the ultrasonic horn 80 moves downward, the left and right first pressure surfaces 81, the left and right second pressure surfaces 82, and the left and right inclined surfaces of the ultrasonic horn 80 are moved. 83, the elements of the left and right fastener element rows EL at the upstream end and the downstream end of the space portion S, and the portions whose shapes are adjusted by the side jaws 70 of the left and right core strings R are pressurized from above, The cut end Et and the core string R (including the sewing thread Y) are melted and pressed. As a result, as shown in FIG. 4, the pressure-cut element cutting end Et (indicated by a dot pattern) is formed into a shape that is crushed downward, and is the pressure-formed portion of the core string R. A certain core string forming portion R1 (indicated by a mesh pattern) is formed into a shape that is tightened in the up, down, left, and right directions as compared with the portion R2 that is not press-formed.

Next, as shown in FIGS. 15 and 16, the ultrasonic horn 80 and the pressing rod 62 are moved up to their original positions, and the first and

second stoppers

40 and 50 are moved down to their original positions. The stop of the fastener chain C is released, and the fastener chain C is conveyed downstream by the chain feeding device 20. Then, by repeating the above operation, the element cutting end Et and the core string R are pressure-formed in each space portion S of the fastener chain C.
