Abstract A device for removing packaging bags in stacks from a collector located downstream of the delivery drum of a packaging bag machine, wherein a U-shaped gripper, the free ends of the legs of which are bent in the direction towards the collector, cooperates with a collector arranged downstream of the delivery drum of the packaging bag machine. The gripper is displaceably guided by its legs owing to tension from helical springs acting on its web within one of the end walls of a substantially frameshaped arm capable of being rotatably displaced in a vertical plane by means of a driven eccentric disc. The gripper is displaceable by a lever arm controlled by a driven cam with a view to clamping the stack of packaging bags on the gripper between the bent legs of the latter and the frame-shaped arm which is capable of being rotatably displaced or with a view to releasing the stack of packaging bags, respectively.

A device for removing packaging bags in stacks from a collector located downstream of the delivery drum of a packaging bag machine, comprising a. a U-shaped gripper arranged for co-operation with a collector and having legs connected at one end by a web and bent at the other end in the direction towards said collector; b. a rotatable eccentric disc; c. a substantially frame-shaped arm having side and end walls and arranged to be rotatably displaced in a vertical plane when the eccentric disc is rotated, the legs of said U-shaped gripper being displaceably guided in one of the end walls of said substantially frame-shaped arm; d. helical springs arranged to act between the web of the Ushaped gripper and the other end wall of the substantially frame-shaped arm; e. a rotatable cam, and f. a lever arm controlled by said rotatable cam and arranged to displace said U-shaped gripper with a view to clamping or releasing a stack of packaging bags on the U-shaped gripper between the bent leg ends of the latter and the substantially frame-shaped arm.
