Abstract

The present invention provides for safe and simple replacement or removal of individual feeders from a placement machine without any loss in performance by using a signal means to emit a signal to the CPU of the placement machine when a feeder is removed. Upon receipt of this signal, the CPU controls the pick-up head in such a way so that it does not collide with the feeder being removed. If the pick-up head is located directly above the pick-up position of the feeder to be removed, it can be moved momentarily upwards or sideways thanks to its fast drive before a collision occurs. If the pick-up head is located just on the way to the pick-up position of the feeder, the procedure is momentarily aborted so that a collision can be avoided.
