Definitions

  • the present invention relates to-an arrangement for the feeding and cutting-off of a precreased packing material web, comprising a rotating feeding mandrel, a rotating roller placed parallel with the feeding mandrel, a number of driving means and a cutting-off device.
  • the package was formed until now into a tube in the packing material factories by creasing, cuttingoff and glueing.
  • the feeding and cutting-off take place in machines designed for this purpose, the packing material being fed from rolls and being cut off at the same time as the individual blanks are being creased. Afterthe creasing the sheet is folded to a tube and is glued, the edge zones of the sheet being made to overlap one another.
  • the packing material which has undergone this operation takes up much room and consequently freight and storage costs are very high.
  • the said disadvantages are overcome through the invention which is based on the principle that the packing material web is fed over amandrelwhich is provided with a number of edges, the mutual distance of which corresponds to the distance between the creases.
  • the invention is characterized in that the said feeding mandrel has a number of mutually parallel edges, between which the feeding mandrel is provided with winding spaces whose length corresponds to the distance between the creases of the precreased packing material web.
  • FIGS. 1-6 show a feeding mandrel in accordance with the invention in different positions during the feeding of a packing material web
  • FIG. 7 shows a package blank
  • FIGS. 8 and 9 show variants of a feeding mandrel.
  • FIG. 1 shows a feeding and cutting-off arrangment for a packing material web, which arrangement comprises a mandrel l which is provided with a number of plane sides 4, 5, 6 and a curved side 7, driving means 3, 28, 29, 30, 31, 32, 33, 34, a cutting-off device with a counterpressure plate 9, a rotating roller 8 placed parallel with the mandrel and a pair of rollers l0, 11, through which passes the packing material web 16 in order to obtain sufficient tension.
  • the cut edge 26 of the material web shall be placed in conjunction with the knife 2.
  • the drivers are made to come into operation at the'same time as the mandrel 1 and the roller 8 commence their rotating movement.
  • Suitable driving means are in this connection suction heads, which by means of a valve can be connected on the one hand to a source of vacuum and on the other hand to the atmosphere. In a first stage it is appropriate for the suction heads 28,
  • the driving means 28, 34 are connected to the atmosphere, the packing material web 16 detaching itself from the side 5 of the feeding mandrel as shown in FIG. 4.
  • the suction head 32 is connected to a source of vacuum, the web 16 being made to rest against parts of the dished side 7 of the mandrel.
  • the packing material web is in contact with the whole of the dished side 7 of the mandrel, the driving means 31 also being cut in.
  • FIG. 6 is shown the position which the feeding mandrel assumes immediately before a package blank is cut off from the packing material web 16.
  • the roller 8 and the feeding mandrel 1, which have rotated synchronously, are given such a position at this stage that the knife 2 and the counterpressure roller provided in the roller 8 are placed right opposite one another, the counterpressure roller pressing the packing material web 16 against the knife 2 with the object of cutting off the web.
  • the driving means 29, 30, 31, 32 are connected to a source of vacuum, which prevents the material web from sliding off the mandrel during the cutting off of the web.
  • the creases of the packing material web were made to coincide with the edges 12, 13, l4, of the mandrel and a possible sliding of the material web was corrected.
  • the packing material web 16 is retained against the sides of the mandrel with the help of the driving means also after the cutting off of a blank, the packing material will be fed and cut off continuously.
  • the mandrel shown in FIGS. 1-6 has four sides, one side being dished so that a longer winding space, that is to say the length of packing material which is required for covering the side, should be obtained.
  • a longer winding space is necessary is, that the package blank preferably comprises four plane surfaces 17, l8, 19, and one smaller surface 21, which is folded in the crease 22 against the edge region of the package wall 20 with the purpose of being sealed against the same, so as to form a longitudinal joint.
  • the cutting-off device 2 will cut off the packing material web so that a narrow surface 21 and a wider surface 20 are obtained.
  • the feeding mandrel may also have the shape shown in FIG. 8, where the dished side 7 is replaced by two plane sides, whose winding length between the edges of the mandrel corresponds to the width of the surfaces 20, 21.
  • the knife must be applied to the region of the edge between the two plane sides 35, 36.
  • the appearance of the feeding mandrel may also be varied within the scope of the invention in such a manner that not all the creases of the web coincide with the edges of the mandrel, but for example only every other, which in certain cases is sufficient for the guiding of the web.
  • a package blank is 4 wound up on half the mandrel, the mandrel being equipped appropriately with two knives which are situated diagonally opposite one another according to FIG. 9.
  • the roller 8 is provided with two counterpresusre plates 9 which are applied directly opposite one another.
  • a device for continuously feeding and cutting off predetermined lengths of a continuous web of packaging material having spaced, parallel, transverse creases therein comprising a rotatable mandrel provided with a plurality of outer faces each being parallel to the axis of rotation of said mandrel and having parallel transverse edges for engaging the transverse creases of that portion of the web which is in engagement with at least one face of said rotatable mandrel for feeding said web, at least one transverse cutting means disposed in at least one face of said mandrel and spaced from the transverse edges of said at least one face, and at least one counterpressure plate rotatable in synchronism with said mandrel about an axis parallel with theaxis of rotation of said mandrel so that said at least one counterpressure plate will cooperate with said at least one transverse cutting means to cut said web at predetermined locations along the length of the web after the web has been fed by said mandrel to the location of cooperation between said cutting means and said counterpressure plate.
  • a device as claimed in claim 1 wherein at least one face of said mandrel is curved circumferentially of said mandrel and in which one of said at least one transverse cutting means is disposed.
