Stapling device

Abstract

A device for connecting products composed of stacked and continuously conveyed webs or sheets of paper or the like, wherein the webs or sheets are connected by a wire-like stapling material which can be cut and deformed into individual clamps. The stapling device includes a supply roll with conveying unit for the stapling material, a cutting device for cutting the stapling material to a length required for forming the clamps, a clamp forming unit, a plunger for pushing the formed clamps into the product and a clamp closing unit. The supply roll with the conveying unit, the cutting device and the plunger of the stapling device are mounted on a rotatable drum-shaped body which approximately contacts the product on one side thereof transversely of the conveying direction. The clamp forming unit is composed of a pocket provided in the drum-shaped body and a radially displaceable clamp forming body which rotates synchronously with the drum-shaped body and is mounted on the same side of the product as the drum-shaped body, wherein the axis of rotation of the clamp forming body extends parallel to the axis of the drum-shaped body. The clamp closing unit is mounted on a rotatable body which is located on the side of the product opposite of the drum-shaped body and can also be driven synchronously with the drum-shaped body.
