Abstract
Each pack has a pair of opposite edges and a pair of locating pins, and is also provided with pairs of holes separated by a distance equal to that between the pins to enable the packs to be stacked in offset manner, with the pins inserted inside the holes of the underlying pack. The loading and unloading device has a loading station and an unloading station located on either side of the worktable; and a transfer device movable between the stations and a fixture on the worktable for clamping the pack for machining. An unpinning mechanism for unpinning the pack has punches which are activated to remove the pins from the pack before the pack is deposited at the unloading station.
