Definitions

  • ABSTRACT A foil blank and envelope made therefrom for enveloping a cigarette block in a cigarette wrapping machine with side folds on the narrow sides, in which the foil sections which overlap each other at the narrow sides of the envelope extend at a slant while the width of the respective outer side increases toward the head portion of the envelope in such a way that the corner during the preparation of the head fold rests on the last cigarette of the outermost cigarette row.
  • the present invention relates to an envelope for enclosing a block of cigarettes in a cigarette wrapping machine with lateral folds on the narrow sides and, more specifically, concerns an envelope of this type which is made from a foil blank.
  • the invention furthermore relates to a method of preparing the envelope and to a de vice for practicing this method.
  • Cigarettes wrapped in cigarette packs are in addition to the wrapper proper surrounded by an envelope of a foil laminated with aluminum, the foil tightly enclosing the block formed by the cigarettes.
  • the foil blank of the envelope surrounding the cigarette block has heretofore been placed parallel to the edges of the cigarette block in order to permit a proper folding.
  • a considerable overlapping of the lateral folds is necessary in order to assure that during the folding of the top fold no bulges will form.
  • the lateral overlapping portions respectively rest on the last cigarette of the outermost rows so that also a depression between the outer rows cannot cause any faults when effecting the top fold.
  • FIG. 1 diagrammatically illustrates a cross section through a portion of a cigarette block surrounded by an envelope as it represents the present state of the art.
  • FIG. 2 shows a foil blank for the envelope of FIG. 1.
  • FIG. 3 diagrammatically illustrates a cross section through a portion of a cigarette block surrounded by an envelope according to the invention.
  • FIG. 4 represents a foil blank according to the invention.
  • FIG. 5 is a partial section and partial side view of a device according to the invention for placing the foil blank in an inclined position.
  • FIG. 6 is a front view of the device shown in FIG. 5.
  • the envelope according to the invention is characterized primarily in that the foil portions which overlap at the narrow sides extend at an incline while the width of the respective outer portion increases toward the top side of the envelope in such a way that the corner during the forming of the top fold rests on the last cigarette of the outermost row.
  • the method for making the envelope according to the present invention is characterized primarily in that the rectangular foil cross section is prior to enveloping the cigarette block placed at an incline. This placing at an incline represents such a simple method that it can be carried out by most simple means without interfering with the heretofore customary steps.
  • the device comprising a cutting device separating the foil blank from a roll of foil and including a cutting roller with counter roller and also comprising a folding device for forming the envelope
  • the cutting device is followed by a roller pair which cooperates with resilient counter rollers and in which the two rollers rotate at different circumferential speeds.
  • the two rollers are connected to a common shaft and have different diameters.
  • the device for practicing the method according to the present invention merely requires that in the transporting path between the cutting device and the folding device there is arranged one roller pair which in view of the different diameters of the rollers has different circumferential speeds so that after the cut off foil blank has been grasped, a placing of the foil blank into a slightly inclined position is effected prior to the foil blank reaching the folding device.
  • the invention can thus be practiced by extremely simple means so that a considerable economic advantage is realized.
  • a further saving in material is obtained when the knife in the cutting roller is, in conformity with the present invention, arranged at an angle with regard to the axis of rotationwhich angle corresponds to that angle by which the foil blank is inclined.
  • a front and a rear cut edge is obtained on the foil blank which edges will be parallel to the edges of the cigarette block to be enclosed after the placing of the foil blank at an incline.
  • the envelope thus not only obtains a top fold with parallel edges but also yields a further saving in material.
  • the cigarette block 1 illustrated in FIG. 1 and comprising three rows of cigarettes la is surrounded by an envelope 2 which is made of a foil blank 3 in conformity with FIG. 2.
  • the foil blank 3 is in a manner known per se folded by means of lateral folds on the narrow sides 2b to form an envelope 2 while the narrow sides 3: of the foil blank 3 overlap to a great extent.
  • the wide sides 2a of the envelope 2 are formed by the wide sides 3b of the foil blank 3 which latter has a smooth bottom 3a.
  • the withdrawal opening of the envelope 2 on the top side is formed by top portions 3d of the foil blank 3 after the cigarette block 1 has been introduced into the envelope 2.
  • the foil blank 4 according to FIGS. 3 and 4 be placed at an incline or slant.
  • the width of the blank section 46 increases toward the top side of the envelope 2 in such a way that the corner will during the forming of the top fold rest upon the last cigarette la of the outermost row.
  • the blank section 4d of the blank 4 which at this area is narrow merely covers the last cigarette la of the adjacent row as is particularly clearly shown in FIG. 3.
  • the foil blank 4 is provided with a smooth bottom 4a, with the customary wide sides 4b and with the top portions 4e which, after insertion of the cigarette block 1 into the envelope 2 which is open at the top side, form the top fold.
  • FIGS. 5 and 6 illustrate a device for placing the foil blank 4 at a slant in a cigarette wrapping machine.
  • the foil blank 4 which is withdrawn from a roll or reel is cut off by a cutting device which comprises a cutter roller 5 and a counter roller 6, both rollers being journalled in a frame 7.
  • the cutter roller 5 is connected to a drive shaft 8 which by means of a pulley 8a is by a belt 9 drivingly connected to a shaft 10 which likewise has keyed thereto a pully 10a.
  • shaft 10 Keyed to shaft 10, which in feeding direction of the foil blank 4 is arranged behind the cutting device, are two rollers 12 and 13 respectively cooperating with counter rollers 14 and 15.
  • Each of these counter rollers 14 and 15 is journalled on a lever 16 which is slightly pivotable against the thrust of a spring 16a.
  • the roller 13 has a slightly larger diameter than the roller 12. Inasmuch as both rollers 12 and 13 are keyed to the same shaft 10, a slightly higher circumferential speed of the roller 13 is obtained. As a result thereof, the rollers 12 and 13 bring about a predeterminable slanting of the foil blank 4 guided between the guiding plates 17 as soon as the blank 4 has been cut off from the foil roll by the cutting device. The foil blank 4 thus will in slanted position move into the folding device following the cutting device so that during the folding operation the folding lines indicated in dash lines in FIG. 4 will be obtained.
  • FIG. 6 shows that the tension of the belt 9 is maintained by a tension roller 11.
  • FIG. 4 shows in dot-dash lines the course of the cut which is obtained when the knife in the cutter roller is arranged at an angle with regard to the axis of rotation, this angle corresponding to the angle by which the foil blank 4 is inclined or slanted by the rollers 12 and 13.
  • the slanted arrangement not only brings about that the blank portions for the top fold will be symmetrical but also results in a further saving in material.
  • a method of making an outer wrapping around a cigarette block in a cigarette wrapping machine using a foil blank of more narrow width than conventional size to save foil blank material which includes in combination the steps of: preparing a one piece rectangular foil blank having a longitudinal central portion comprising a bottom section and a front section and a rear section collectively to contain a predetermined number of cigarettes, said rectangular foil also being provided with irregularly tapered sections arranged on opposite sides of said central portion, the lateral section at one side of said central portion decreasing in width from one end each of said foil blank to the opposite end of said foil blank and the lateral section on the other side of said central portion correspondingly increasing in width from said one end of said foil blank to said opposite end of said foil blank, and inclining said foil blank placed into the cigarette wrapping machine at an inclined position purposely so that the confining longitudinal edges of said central portion which also form the folding lines for said irregularly tapered lateral sections extend substantially parallel to the direction in which the wrapping machine feeds said foil blank though when folding is completed there results a rectangular outer wrapping
