ABSTRACT:
An apparatus is disclosed for inserting elements into a workpiece. The apparatus includes reciprocating feeding means movable between first and second positions for sequentially advancing a supply strip of integrally connected preformed elements towards the workpiece. Actuating means cooperate with the reciprocating feeding means for rotating the reciprocating feeding means when the reciprocating feeding means has reached its second position. During the rotation, the supply strip of elements rotates with respect to the lead element which has been inserted into the workpiece thereby breaking the lead element from the supply strip. As the feeding means, holding the supply strip, rotates back to its initial position, the interaction of the supply strip and the lead element which has been inserted into the workpiece polishes and wipes away any burr that may have remained during the severance. The supply strip may comprise a plurality of integrally connected preformed terminal pins which may be utilized in the electrical and electronics industry after insertion into a substrate such as a printed circuit board, but other supply strips of integrally connected preformed elements may be utilized for application in non-electrical industries.
