Abstract
A pick-and-place machine having magnetic elements which hold down the chips at the pick stations, thus preventing shingling, and also hold such chips at the pick stations adjacent a stop element. The magnetic elements create magnetic forces in two directions relative to chip elements having magnetizable terminal portions. The magnetic elements are provided in combination with feed apparatus that is adapted to stop, when the associated groove is full of chips, rather than causing the machine to jam.
