Abstract: The invention relates to a roll holder for a label roll, in particular for a label printer for a packaging machine for wrapping products with a packaging film, having an horizontally arranged, fixed-position holding mandrel whose one end is fastened to a carrier and whose other end projects in an unsupported manner from the carrier, and having a first roll mount and a second roll mount separate from the first roll mount, wherein the first roll mount is configured to engage into a first end of the label roll, and wherein the second roll mount is configured to engage into a second end of the label roll, such that the label roll is receivable between the two roll mounts, with the second roll mount being pushable onto the holding mandrel from the unsupported end of the holding mandrel.

Abstract: A packaging machine packages items using film. The packaging machine includes: a film transporter for feeding film; and a cutting device for cutting film. The cutting device is transferrable by a driving force from a rest position into an extended position. The film is severable by the cutting device in the extended position. The cutting device is connected to a housing surrounding the cutting device via a return mechanism. The return mechanism is activatable upon the cutting device being transferred from the rest position into the extended position. A return force in a direction of the rest position is exertable by the return mechanism in the activated state on the cutting device in its extended position, the force being greater than a return resistance of the cutting device in its extended state by which the cutting device is held in the extended state without action of the driving force.

Abstract: A packaging machine for packaging articles with a stretchable film includes: a weighing device, which is rigidly fastened to a machine frame, for determining a weight of an article; a film transport device, which is fastened to the machine frame, with a belt conveyor for transporting the film to the article to be packaged; and a folding mechanism for folding the film. The folding mechanism having: two lateral slides that push the film left and right under the article to be packaged; and a rear slide which pushes the film from behind under the article to be packaged. The lateral slides and the rear slide are fastened to the machine frame via at least one damping element which is designed in such a way that it prevents or at least dampens transmission of mechanical vibrations of the lateral slides and of the rear slide to the machine frame.

Abstract: A packaging machine for packaging products to be packaged by means of a stretchable film includes: a film transport device for a film feed to a product to be packaged; a first and a second belt conveyor for transporting the film, the belt conveyors each including a first and a second belt conveyor that are synchronously driven in a film transport direction prescribed by the film transport device and are arranged side by side, at least the second belt conveyor device being movable in a direction perpendicular to a film transport direction; and a movable film guiding element, by which the film is introducible into the film transport device, the film guiding element including a guide plate for guiding the film that has a first recess and a second recess in an upper edge in a vertical direction toward the belt conveyors.

Abstract: A film transport device for transporting a stretchable film includes: at least one belt conveyor, the belt conveyor having two opposing transport belts for transporting the film and a first and a second deflection roller, each of which guides one of the transport belts in continuous circulation and is arranged at an end in a respective transport belt. An end portion of the first deflection roller projects past an associated transport belt, the first deflection roller having a first transport ring at the end portion along its periphery. An end portion of the second deflection roller projects past an associated transport belt, the second deflection roller at the end portion along its periphery having a second transport ring. A first contact surface of the first transport ring extends with mechanical friction along a circumference of the first deflection roller.
