Definitions

  • the present invention relates to a method of making carton tubes as defined in claim 1.
  • Methods of the kind referred to above start with providing a wide sheet of carton material. This wide sheet is then divided into strips of a width that is suitable for making the tubes. The strips are coated with an adhesive and advanced towards and onto a mandrel to form carton tubes.
  • FR-A-1,301,954 discloses a method in which blanks are first cut and then the blanks are fully coated on one side with an adhesive. After the blanks are wound onto a mandrel, the adhesive is activated.
  • the object of the present invention to provide a method of the kind referred to above, with which it is possible to make carton tubes or similar articles in a process not requiring constant supervision, and this object is achieved with a method of said kind, according to the present invention exhibiting the features set forth in claim 1.
  • the process of applying the adhesive to the sheet material can take place, so that no adhesive in a condition, in which it can be deposited in an undesired manner on parts of the machine, will be present in the latter in any step of the method.
  • the wide sheet material will be provided with a coat of adhesive at some central location comprising specialized equipment for applying adhesive to the sheet material and winding the latter with the adhesive in a non-tacky state into rolls.
  • the adhesive is a water-soluble adhesive.
  • the present invention also relates to
  • Figure 1 shows a supply of wide sheet carton material.
  • Figure 2 shows the strip material being advanced onto the mandrel.
  • a wide sheet of carton material 10 as shown in Figure 1 has peripheral areas 11.
  • the wide sheet carton material is coated with an adhesive that is normally not tacky but which can be made tacky by an activating step. When the adhesive is applied to coat the sheet it is normally in an active state. Therefore, the peripheral areas 11 are left uncoated. In this way, no adhesive is spilled during the coating process.
  • the coated wide sheet carton material 10 can then be accumulated, preferably in the form of rolls 12.
  • the wide sheet carton material 10 is divided into sections of strip material 3 as indicated by the intersected lines in Figure 2.
  • the sections originating from the peripheral areas are not further processed and can be recycled.
  • the other fully coated sections 3 can be accumulated, preferably in the form of rolls 1.
  • the fully coated sections 3 are further processed in an apparatus as shown in Figure 2.
  • the adhesive is water-soluble and consequently the coated strips and the finished rolls are fully recyclable.
  • the method of making carton rolls according to the present invention is thus highly environmentally friendly.
  • the carton strip 3 has previously been coated with a thin layer of adhesive of the type that can be made to change from a non-tacky to a tacky state, the non-tacky state being the state within the roll 1 and along the strip 3 as far as the activating unit 5.
  • the adhesive on the strip 3 is changed into the tacky state, in which it remains until having been incorporated in the carton tube 8. From that point, the process of removing the tube 8 from the mandrel 7 continues in any suitable manner.
  • the roll 1 is manufactured in much the same manner as known tape rolls with a coat of adhesive in an inactive state, such as dry water-soluble adhesive, used e.g. for closing and sealing cardboard boxes.
  • a supply of carton strip without adhesive e.g. a roll of carton strip as supplied by a manufacturer of such strip, is placed in a suitable unwinding stand or the like, and then pulling the far end of the strip through
  • the activating unit 5 is placed at some distance from the mandrel 7, but it may just as well be placed close to it, provided - of course - that its activating function is not compromised.
  • a dried, water-soluble adhesive is used on the strip 3
  • the activating unit 5 - in the form of a heat source (not shown) - may be placed closer to the mandrel 7, even some distance downstream from the winding-on point 9, i.e. down and to the right along the mandrel 7.
  • the strip 3 is wound helically about the mandrel 7, the latter having a circular cross section allowing it to remain stationary.
  • the scope of the invention does, however, extend to processes differing from the one illustrated.
  • a strip may be wound in parallel layers on top of each other, either on a round mandrel to form a short cylindrical tube, or on a rotating mandrel having, say, a square, rectangular or other polygonal cross section, so as to form the side walls in a box.
  • a single strip 3 coated with adhesive on one side is used for making the tube 8.
  • the scope of the invention does, however, extend to processes based on two or more strips, of which one or more may not have a coat of adhesive, whereas one or more may have such a coat on both sides, so that the strips are made to interleave in a suitable manner for forming e.g. a tube.
