When rocker arm 1 oscillates, driving slide 2 reciprocates together with feeding finger 3, feeding disks 4, one by one, under plunger 5. Synchronized with this disk feeding mechanism is a mechanism for feeding caps 6 into which the disks are forced by plunger 5. Feeler bar 7, mounted at one end of lever 8, checks whether a cap is ready to receive the next disk, controlling the disk feeding mechanism as follows. If there is a cap under feeler bar 7, lever 8 is in the position shown and when slide 2 travels to the left, latch 9, hinged to feeding-loaded finger 3, slides along lever 8 and its projection a depresses spring tapered button 10. At this, a disk 4 is forced by plunger 5 into a cap 6. When there is no cap under feeler bar 7, lever 8 turns counterclockwise and latch 9, when its projection a meets tapered button 10, is turned out of engagement with slide 2 so that the feeding of disks 4 is stopped. Slide 2 reciprocates idly until a new cap is fed under feeler bar 7. This raises the bar and turns lever 8 clockwise, enabling latch 9 to engage slide 2, and the feeding of disks 4 begins again.
