摘要： The invention relates to a packaging machine for wrapping packaging trays for foods using a packaging film, in particular a plastic film, in which the film is supplied to a holding mechanism having two holding means spaced apart from one another to hold the supplied film at two mutually oppositely disposed sides; in which the spacing of the two holding means from one another is then adjusted: and in which a supplied tray is subsequently pressed toward the supplied film by lifting from below, wherein the holding mechanism is adjusted such that the spacing of the two holding means from one another is reduced.

摘要： 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.

摘要： 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.
