Definitions

  • the invention relates to a method according to the preamble of claim 1 and a Device according to the preamble of claim 6.
  • Such a method and such a device are known from US-A-3 863 425 GB-B-1 429 445).
  • the method of the type mentioned has the advantage that a Packaging web of a certain small width used for rolls of any width can be. This simplifies storage and handling of Packaging web rolls.
  • the method of the type mentioned has the advantage that the resulting straight wraps in the end areas of the packaged Roll these end areas evenly and, if desired, evenly protrude beyond the roll ends, so that they are then evenly radial can be turned inside.
  • EP-A-0 004 471 a device is known which corresponds to the preamble of Claim 6 corresponds with the restriction that the packaging web is not provided alternatively, instead of at an acute angle, also at right angles to the axis of the packaged Role.
  • This known device has a cutting device To cut the packaging line, a knife that runs along a cross is manually movable over the stretching guide. To this Purpose is the knife connected by a rope with a handle, and in opposite Direction with a take-up drum that has a return spring for take-up the rope, and thus to retrieve the knife after it has been manually operated, assigned.
  • the invention has for its object a method and an apparatus for Pack a roll with a packaging web whose width is less than the length
  • the role is to be designed in such a way that the roll is wrapped around essentially without wrinkles becomes, even if the packaging web is not elastic and not shrinkable is, especially if it consists of ordinary wrapping paper.
  • the device shown has the task of a cylindrical Pack roll 10, its axis A and its length L in Fig. 3rd to 5 are shown.
  • the role 10 consists of, for example Printing paper and has a first one in the above drawings left end 12 and a second, right end 14, both as flat end faces are formed.
  • the role is in the company 10 on two parallel support rollers 16 and 18, which in the sense of Arrows in Fig. 1 are driven.
  • a packaging web 20 is used to pack the roll 10 Wrapping paper, the width B of which is considerably smaller than the length L of roll 10.
  • This packaging web 20 is first according to Fig. 3 at right angles to the axis A of the roller 10, while this is rotated, the cylindrical outer surface of the roller in such a way supplied that one consisting of preferably several turns first straight wrap 22 is formed. From the same packaging line 20 will later be shown in FIG. 5 in the area of the second end 14 of the roll 10 a second straight wrap 24 is formed. Both straight windings 22 and 24 protrude by approximately each half the width B of the packaging web 20 over the associated one End 12 or 14 of the roll 10; so it will be a first Overhang 26 or a second overhang 28 approximately from the Width B / 2 formed.
  • the two straight wraps 22 and 24 are as follows through a helical winding 30 of the roll 10 connected with each other: As soon as the first straight winding 22 is almost completed, is in the packaging web 20 on their way to the roll 10 generates first incision 32, which of the second end 14 of the Roll 10 facing edge of the packaging web 20 starts out transverse to their longitudinal direction over the greater part of their Width B extends and ends in the part of the packaging web 20, which then form the first overhang 26, ie beyond of the first end 12 of the roll 10 will lie.
  • the roll 10 arrives at the first incision 32 according to FIG. 4 a place where it is roughly in the same vertical plane lies like the axis A of the roller. Now it is on roll 10 tapered part of the packaging web 20 inclined so that it 4 an acute angle ⁇ with the Axis A forms.
  • the packaging web 20 is parallel to the axis A further rotating roller 10 on its peripheral speed matched, laterally offset, so that the helical wrap 30 arises.
  • the angle ⁇ is chosen so that the individual Windings of the helical wrap 30 overlap each other.
  • a relatively small overlap is shown in FIG. 5; however, the overlap can be significantly larger, for example half the width B of the packaging web 20.
  • a second incision 34 is made in the packaging web 20, the edge facing the first end 12 of the roller 10 the packaging web runs out, transversely to its longitudinal direction extends over the greater part of their width B and in one Area ends, which then form the second projection 24 becomes. Then the part of the packaging web which runs towards the roll 10 20 again set at a right angle to axis A, so that with continued rotation of the roller 10, the second just winding 24 with its overhang 28 is formed.
  • the two incisions 32 and 34 prevent that in the packaging path 20 annoying folds occur when the angle the Packaging web on its way to roll 10 with its axis A at the transition from the first straight wrap 22 to the helical wrap 30, and at the transition from this changed to the second straight wrap 24 according to FIG. 4 or FIG. 5 becomes.
  • a first overlap field 36 and a respectively second overlap field 38 both of which are approximately triangular.
  • two of the first incision 32 or delimited by the second incision 34 triangular surfaces of the packaging web 20 one above the other without To form wrinkles.
  • This desired stacking can be done with Need to be enforced by the affected areas of the Packaging web 20 of one or more air flows or by sucking in opposite directions out of the plane be deflected in the process of making the part that separates them Incisions 32 and 34 were located.
  • the incisions 32 and 34 do not accidentally tear away, they each end in a punched circular hole 40. Beyond this hole 40 may be in the extension of the relevant incision 32 and 34 in the described Changes in the feed direction of the packaging line 20 small Wrinkles; but these are in the supernatant 26 and 28, respectively in a later step in the usual way radially inwards is handled. The wrinkles mentioned remain without any influence on the smoothness and roundness of the wrapped surface roll 10.
  • the device shown schematically in the drawings is suitable with a carriage 42 parallel to the two Back-up rolls 16 and 18 and thus parallel to the axis A of the roll 10 along guides 44 is controlled displaceable.
