ABSTRACT:
A wire insertion apparatus particularly for forming presses and the like comprising at least one pair of insertion rollers between which a wire or rod is periodically advanced by a predetermined insertion length, a crank and connecting rod mechanism connecting at least one of the insertion rollers to a drive shaft for producing a periodic angular movement of the insertion rollers, the mechanism comprising an intermediate lever member pivotally mounted on an axis, first and second linkage rods connecting the intermediate member respectively with an eccentric on the drive shaft and an eccentric mounted on one of the insertion rollers so that rotation of the drive shaft produces angular movement of the insertion roller in response to pivotal motion of the intermediate lever member, and means for shifting the pivot point of one of the linkage rods so as to change the distance between the pivot axis and that rod and thereby change the degree of angular movement of the insertion rollers.
