ABSTRACT:
An apparatus for automatically closing L-slide lock cases travelling with the lateral axis in the direction of travel and stopped intermittently for closing includes selectively positionable support rods for defining a fold line in an open flap, a flap fold member for folding the open flap over the support rods line and moving the top edge of the open flap adjacent the L-slide locks, and a flap tucking member operable on the folded open flap to slide it into the L-slide lock and flatten out the fold. Each of the members may be driven by cylinders in an appropriate sequential manner to accomplish these folding and tucking operations.
