Abstract

A gripper having jaws (11,12) is transported from a first position (FIG. 2) in which it grips a case blank (1) in a flat, folded condition to a second position (FIG. 4) in which the case (8) is erected. Gripping devices (13) on the jaws (11,12) are aligned with one another when the gripper is in its first position. The gripping devices (13) on the jaws (11,12) are oriented at right angles to one another when the gripper is in its second position. Mutual rotation is effected between the jaws (11,12) as the gripper is moved from its first to its second position, in order to unfold a case blank (1) gripped by the gripper jaws (11,12).
