Definitions

  • the invention relates to a method for producing hollow tubes of the tobacco-processing industry and to a format device for an extrusion machine of the tobacco-processing industry, wherein the format device is adapted to form at least one flat-shaped strip of material, which is guided longitudinally through the format device to form a hollow tube, comprising a top format and a sub-format, the sub-format having a format tape guide surface, and comprising a format tape guided or guided along the format tape guide surface by the format device.
  • tubes or hollow tubes for example of cardboard or paper, are used to provide, for example, special filters, such as recessed filters or hollow filters.
  • tubes which are cut to length from hollow tubes, also serve as spacers in heat-not-burn products.
  • a corresponding tube should have a certain stability, which is why it is known to produce multi-walled paper tubes or hollow tubes.

A connection of the ends of the paper strip is made by overlapping or underlapping the paper strip with the folded and bent edge.
  • DE 10 2014 226 019 A1 shows a double-layered tube of the tobacco processing industry, a device for producing such a tube and a method for producing double-layered tubes, wherein two staggered and bonded material strip portions are provided, which are conveyed by a format device, thereby formed into a hollow tube and be formed by overlapping side portions to a hollow tube, in which case the edges of the strips of material are in abutment.
  • a format device thereby formed into a hollow tube and be formed by overlapping side portions to a hollow tube, in which case the edges of the strips of material are in abutment.
  • an endless hollow tube is first produced in a format device that is part of a stranding machine.
  • a format tape is used, which is guided by a format device.
  • the format strip serves as a means of transport for the material strip sections, which are stacked and glued together. Since there is no material in the hollow tube, such as a filter material that presses outward, only little internal pressure can be exerted on components of the format device such as an upper format or a lower format or the format band. This can be a Slip occur, which can be problematic for a quality according to produced hollow tubes. In particular, when there is already a slip, problems may occur because, as is known, the static friction is usually greater than a sliding friction.

This ensures that sufficient pressure is exerted by the rotating device on the at least one strip of material and the format strip.
  • the distance of the rotary device to the format band guide surface in the operation of a strand machine of the tobacco-processing industry in particular automatically adjusted.
  • wear for example of the format band
  • the pressure which the rotary device exerts on the at least one strip of material and the format strip, in particular constant, is set.

  • the distance of the rotary device to the format band guide surface can be adjusted automatically during operation of a stranding machine.
  • two transverse to the longitudinal axis offset merged and bonded with an adhesive material strip are formed into a hollow tube.
  • a hollow tube or a double-layered tube of the tobacco-processing industry can be produced with very high quality.
  • a strip of material as in DE 10 2014 226 019 A1 is first cut longitudinally axial, is provided with adhesive and is brought together offset in the direction transverse to the longitudinal axis, so that a double-layered material strip is fed to the format device.
  • the hollow tube can then be designed so that the lateral edges of the material strips are arranged in abutment in the hollow tube or have only a small distance from each other. In this way, an improved roundness of the hollow tube produced is possible.
