ABSTRACT:
A pneumatic machine for cutting flexible tubing and inserting the cut pieces onto a printed circuit board is disclosed. The machine unwinds a spool of tubular material, cuts a predetermined length off the end thereof and inserts the cut length onto a printed circuit board. The sequencing and timing relationship between the feeding, cutting, and inserting steps is controlled by a cyclic sequencing apparatus which is activated by a foot switch.
A machine for forming and inserting eyelets into a printed circuit board is also described. The eyeleting machine unwinds a spool of tubular solderable material, cuts off a length of the tubular material, and inserts the cut tubing into a printed circuit board hole and then forms a shoulder on both ends of the inserted tubing. The sequencing and timing between the feeding, cutting, and inserting operations is controlled by a sequencing apparatus which is activated by a foot switch.
