Abstract: A folding device and a method for folding over limbs of L-boards at the folding device located upstream of the sealing station in the production direction of a deep-drawing packaging machine. The folding device may include at least one folding member for folding over the limb in a production direction and a hold down device for holding down the folded over limbs. In one embodiment, the hold down device can be activated by a pneumatic cylinder. In another embodiment, the folding device may be moved by a servo motor or pneumatic cylinder. The method includes moving the thermo-formed troughs of a packaging film, placing the product and the L-boards in the trough, folding the limbs of the L-boards, and holding down the limbs once folded.

Abstract: The invention relates to a conveying unit for guiding and conveying a material web in a thermoform packaging machine, comprising, on either longitudinal side of a machine frame, a conveyor chain, a chain wheel and a guide device. A chain link of the conveyor chain and a clamp guide can be implemented together and in one piece as a shaped part.
