Definitions

  • the invention relates to a device for producing a tube, in particular a drinking tube, according to the preamble of patent claim 1.
  • the supply of the strip material from a supply roll to the winding device is provided at a certain angle, which determines the area of the overlapping edge zones of the strip material to form a tube.
  • the tape material Before the tape material is wound on the winding mandrel, it passes through an adhesive device, as a result of which liquid adhesive is applied to the edge zones in the overlap area.
  • the overlapping edge zones of the strip material are fixed to one another, so that a tube is formed which can be transported away from the winding mandrel in the direction of the cutting device.
  • the tubes are immersed in paraffin or another medium that seals the paper against moisture so that they can be used as drinking straws.
  • Such a device for producing a drinking straw has the disadvantage that a complex design of an adhesive device is provided which is only allowed to apply a very specific amount of adhesive to the strip material and which must be able to be limited and adjusted in the edge zone.
  • a complex design of an adhesive device is provided which is only allowed to apply a very specific amount of adhesive to the strip material and which must be able to be limited and adjusted in the edge zone.
  • the adhesive will emerge laterally from the overlap area and can therefore be applied to the winding mandrel, which means that bonding or at least difficult winding between the Winding mandrel and band material can be given.
  • the adhesive application is too low, so that overlap areas can be present without an adhesive connection. This can lead to disruptions in the production process, since the helical or helical strip material expands and its helical shape can dissolve.
  • a further disadvantage is that the paper is coated with paraffin for the production of such drinking straws or that paraffinated paper tape materials are used. Due to the insolubility in water and in high-percentage alcohol of the paraffin, the disposal of such paraffinated straws is no longer permitted, so that the advantages of paraffin as a colorless, odorless and tasteless impregnating agent for straws can no longer be used.
  • the invention is therefore based on the object of providing a device for processing a strip material which enables simple and secure connection of the strip material in the overlap region of the wound helical strip material and a strip material which can be used to produce the tubes, which is disposable and recyclable.
  • biodegradable Tape material can be used, which can have the required impregnation properties, for example for use as drinking straws, and at the same time enables a satisfactory adhesive connection in the overlap area of the helically arranged tape material.
  • the adhesive device according to the invention has the advantage that a simple and quickly adjustable adhesive device is created, which creates a secure adhesive connection.
  • a simple and quickly adjustable adhesive device is created, which creates a secure adhesive connection.
  • the surfaces of the coated material can be brought into a state in which they bond to one another and can form a firm connection after the end of the exposure time. It is advantageously provided that the energy can be applied selectively or in planar form.
  • the design of the adhesive device according to the invention has the advantage that an adhesive connection can be created without the use of additional adhesives or auxiliaries which are necessary for the formation of a secure adhesive connection. This can save adhesive, for example. Furthermore, a further component for the production of a tube can be omitted which would have to meet the high requirements with regard to disposal and recyclability.
  • the adhesive device according to the invention has the advantage that, depending on the tape material used, with a corresponding coating, the type of energy supply can be freely selected and can be adapted to the tape material and to the processing speeds.
  • the supply of energy can advantageously be provided in the form of heat, waves, rays or the like.
  • the adhesive device is designed as an ultrasound head.
  • This advantageously has a sonotrode tip which can be adapted to the width of the adhesive connection or the width of the overlap area, so that, for example, an adhesive connection can be produced over the entire width of the overlapping edge zones.
  • Dependent on The ultrasound frequency of the strip material and the coating can be selectable, the sonotrode tip being operated above 20 KHz, preferably in a range from 30 to 60 KHz.
  • the adhesive device is designed as a laser.
  • a bundled light beam with high energy can act on the overlap area and cause the coating to melt or melt quickly, so that a satisfactory adhesive bond can be produced even at very high working speeds.
  • the adhesive device emits electromagnetic waves.
  • the adhesive device can be designed as a light source, which has a focusing device that bundles and adjusts the light beams. Analogous to the laser, waves can also act on the overlap area here, whereby an even more cost-effective design can be achieved compared to the laser.
  • the adhesive connection can be produced after the winding process.
  • the adhesive device is advantageously provided after the winding device.
  • the strip material can thus be fed directly from the supply roll to the winding mandrel, the strip material first being converted into a helical tube shape by means of the winding device.
  • the adhesive device then creates an adhesive connection between the strip material in the overlap area.
  • the strip material is made of a plastic coating, advantageously a coating 5
  • This plastic coating is present in a ratio of less than 20 percent by weight to the strip material formed from paper. As a result, such a tube can be disposed of without any problems and is well within the applicable regulations for disposal and recyclability.
  • a tape material is formed with a double-sided coating of 5 to 25 g / m 2 , and that 70 to 140 g / m 2 paper can be used as the carrier material.
  • the strength of the paper can increase the inherent rigidity of the tube and thus withstand higher kink loads.
  • a 110 g / m 2 paper can advantageously be provided.
  • the percentage of the plastic coating can be adjusted, it being possible to form a particularly stiff tube with 110 g / m 2 paper and a coating on both sides of 10 g plastic.
  • the tube can advantageously be produced with a strip material.
  • a double-sided coated strip material is used, in which case the tube is then wound in two layers.
  • This two-layer arrangement enables a tube to be designed with a high degree of rigidity.
  • the inner and outer band material are advantageously arranged offset from one another, so that a high degree of overlap can be formed.
  • the inner and outer layers are wound in such a way that the edge areas of the strip material are butted. This enables a so-called sandwich construction.
  • the coating is formed from corn starch or dextrose-containing materials that can be welded by heat. To a certain extent, this coating is also moisture-impregnating. This coating can advantageously be destroyed by bacteria, which are basically present in composting.
  • a cutting device is provided with a rotor which is at its free end Has cutting knife.
  • This cutting knife is advantageously driven by a three-phase motor, which sets the rotor in sinusoidal rotational movements.
  • the rotor is constantly in motion.
  • the rotor has a stop-and-go operation. After each full revolution, the rotor is stopped briefly until the required tube length has passed the interface before it is driven again.
