  • Publication number: 20240149520
    Abstract: The present invention relates to an apparatus for producing inline stretched tubular foils by the blowing process, having a blown foil system comprising an extruder, a blowing head, a cooling ring, a calibrating basket, a flat laying unit and a reversing turret haul-off, having a stretching system for monoaxially stretching the laid flat foil in the machine direction and with a first thinness control system which operates segmented control zones in the cooling ring to form thinness sections so that, during stretching, a foil is produced with a thickness profile having the smallest possible deviations from the medium foil thickness over the complete foil width. To increase the accuracy and speed of the first thinness section control system, a second thinness section control system is provided which controls two opposing heat sources between the calibrating basket and the flat laying unit and which can be connected to the first thinness section control system.

  • Publication number: 20230173740
    Abstract: The invention describes a stretching device for stretching a plastic film in its transport direction, having a first roller that can be driven by a first drive and can be rotated at a first rotational speed, and having a second roller that can be driven by a second drive and can be rotated at a second rotational speed, the second rotational speed being greater than the first rotational speed, the second roller being arranged downstream of the first roller in the transport path of the plastic film. The device is characterized by means of varying the amount of air between the plastic film and flat elements of the first roller and/or the second roller on which the film rests.

  • Publication number: 20230173739
    Abstract: The invention relates to a stretching device for stretching a plastic film in the transport direction thereof, having a first roll, which can be driven by a first drive and can be rotated at a first rotational speed, and having a second roll, which can be driven by a second drive and can be rotated at a second rotational speed, wherein the second rotational speed is greater than the first rotational speed, and the second roll is arranged downstream of the first roll in the transport path of the plastic film, wherein at least one of the rolls is a roll through which air can flow inwards from the outside. According to the invention at least one roll through which air can flow can be continuously cleaned.
