Is supplied.

As soon as one nib 3 snaps to the lowermost end of the second slide 79 descending, the nib guide 55 moves to the right, and the nib 3 is caught by the slide 79 and beats the stopper 59. It is mounted on the back of the forward end of the cap feeder 95 which is advanced. The cap 1 located in the groove of the catcher 81 with the second slider 79 being bitten by the second slider 79 where the tip 3 is lowered when the cap feeder 95 retreats while the second slider 79 is still lowered. Supplied to the cap 1 and the tip 3 by the action of the action portion described later, the button 5 is completed. The stopper 59 is returned to its place by the elastic member while one nib 3 is supplied to the catcher 81 and the next nib is waiting.

As the drive shaft 25 rotates, the cam 15 in the center portion of the drive shaft rotates, and the rotational motion is converted into the vertical movement by the cam 15 and the connecting member 75. As the connecting member 75 moves up and down, the connecting member 75 and the action member 73 to which one end is connected are vertically moved. When one end of the actuating member 73 moves up and down, the first slider 77 connected to the other end of the actuating member 73 moves up and down. According to the vertical movement of the first slider 77, the cap 1 and the tip 3 are compressed by the catcher 81 to form a snap button 5.

When the slider 77 is at the bottom dead center and is fully compressed, the second slider 79 located inside the lower portion of the first slide 77 is compressed, and the catcher 81 supported by the bottom by an elastic member such as a spring is provided. The cap and the tip are engaged by the action of the maximum force while descending slightly down. Of course, when the cap 1 and the nib 3 are compressed and engaged, the cap feeder 95 is in a reversed state.

The snap button 5 completed through the above process, when the cap feeder 95 advances to supply the catcher 81 with the cap to be assembled next, the forward end portion of the cap feeder 95 is advanced. It is pushed by the button storage unit 23 to be collected. Thus completed snap button (5) is attached to the desired fabric using the protrusion of the nib (3).
