Abstract
On a drilling machine for drilling packs of printed circuit boards, the packs are loaded and unloaded between a support and the work table by engaging a pin on the pack via a pair of jaws and by moving the table longitudinally. The pack is retained by a bar for enabling two bars to engage and locate a further pin on the pack; further retaining elements provide for sliding the pack in relation to the table; and a member is activated for aligning the pack against a fixed locator. The support forms part of a rack operated vertically in steps by a lifter located behind the drilling machine.
