Definitions

  • the invention relates to a rolling installation for making creases in a web of material, such as cardboard, comprising a pair of rotary rollers, each of which is mounted at its two ends in bearings and each of which is provided with roll surfaces by means of which the rollers are Tollable with respect to one another leaving a gap between the roll surfaces, one of which rollers is provided with at least one ridge and the other of which is provided with at least one groove, and the rollers are synchronised such that at the location of the gap each ridge is opposite a groove.
  • a rolling installation of this type is known.
  • the web of material is deformed in the gap between the two rollers by means of an opposing ridge and groove such that a crease remains.
  • the web of material can then easily be folded at the location of such a crease, as is customary in, for example, the production of packaging, in particular, but not exclusively, cigarette packs.
  • packaging in particular, but not exclusively, cigarette packs.
  • the so-called "hard box” packaging made of cardboard and the closing flap hingeable about a crease were developed.
  • the aim of the invention is to be able to provide a further developed packaging. Said aim is achieved in that with the abovementioned rolling installation multiple parallel ridges are provided on the one roller and corresponding multiple parallel grooves are provided on the other roller in order to form multiple parallel creases in the web of material, at the location of which creases a rounded corner can be formed.
  • multiple creases can be produced so close to one another that the finished packaging no longer has any sharp angular transitions but smoothly flowing, rounded corners.
  • Such a flowing character of the corner region between two walls of, for example, a cigarette pack increases the attractiveness to the public, which gives the manufacturer a competitive advantage and makes the packaging more exclusive.
  • a significant advantage of the very small mutual spacing of the creases is that shaping of an evenly curved corner region is no problem whatsoever. Since all creases can be identical, there is no preference for the material to fold at the location of the one crease before folding at another crease, with the result that all creases bend to the same extent through a small fold angle when the packaging is produced. The result is the even, curved progression in the corner regions, which has already been mentioned.
  • the multiple parallel ridges are accommodated on a local elevation on the roller surface.
  • the multiple ridges and grooves are designed to form 7 creases, with a mutual spacing of approximately 0.8 mm. Other numbers and dimensions are also possible.
  • At least one pair of mutually parallel series of multiple ridges and grooves are provided for forming a pair of multiple parallel creases, it being possible to form a rounded corner at the location of each of said series of creases, on either side of a flat panel.
  • the invention also relates to an installation for the production of a blank for forming a box or pack, such as a cigarette pack, comprising a rolling installation as described above, a cutting roller installation provided with a cutting roller with blades, and a contra-roller with stripping pins for the waste material which has been cut out, which stripping pins can be accommodated in recesses in the cutting roller at the location of the gap between the cutting roller and the contra-roller.
  • the material which has been cut off and has become surplus is removed by means of the stripping pins, which are known per se.
  • the aim of this is to reduce the amount of waste as far as possible. As a consequence of this all that remains are thin strips of material, which are difficult for the stripping pins to pick up, at least without tearing the waste. Once the waste tears, pieces thereof get between the rollers, as a result of which the process is disrupted.
  • each stripping pin is accommodated in a block, which block is let into the surface of the contra-roller.
  • each stripping pin has a widened head which is in contact with a stop on the block, which stop faces the cutting roller. The widened head is locked in place by means of a headless screw, which interacts with screw thread in the sunken hole in which the head is located.
  • Each stripping pin also has a shank provided with a pointed end, the pointed end of the shank protruding from the block.
  • Figure 1 shows a partial view of a pair of rollers for a rolling installation according to the invention.
  • Figure 2 shows a detail of the two rollers.
  • Figure 3 shows a partial view of an installation for the production of a blank.
  • Figure 4 shows a detail of the two rollers in Figure 3.
  • Figure 5 shows a blank.
  • Figure 6 shows a detail of a packaging.
  • rollers 1 and 2 shown in Figure 1 are rotatably mounted by means of respective stub axles 3, located on either side, in a frame which otherwise is known and is not shown.
  • the rollers are synchronised by means of respective gears 5, 6.
  • the rollers enclose a gap 7 between them, which gap is defined by the respective roll surfaces 8, 9 which roll over one another.
  • Roller 1 has a number of patterns 10 consisting of ridges 11 (see Figure 2), whilst roller 2 has a number of patterns 12 consisting of grooves 13 (see Figure 2). As can be seen in Figure 2, the ridges 11 are located on an elevation 20. As a result a gap 7 can remain clear between the rollers 1, 2.
  • the patterns 10, 12 each define pairs of creases for a cigarette pack, specifically one pair 14 for the front, one pair 15 for the back and one pair 16 for a flap which adjoins the front.
  • FIG. 5 The finished blank, as creased by means of the rollers according to Figure 1, is shown in Figure 5.
  • the creases obtained are indicated by reference numerals 17 and the panels obtained are indicated by reference numerals 14', 15', 16'.
  • Figure 6 shows that, for example, there is a transition from back panel 15' via the rounded corner 18 formed by means of said crease lines 17 to side panels 19.
  • the blank shown in Figure 5 has been obtained by cutting out the blank from the web of material, after the crease lines have been made by means of the pair of rollers according to Figure 1, by means of the pair of rollers 21, 22 shown in Figure 3.
  • These rollers are also rotatably mounted by means of stub axles 23, 24, respectively, and roll over one another by means of the roll surfaces 25, 26.
  • the synchronisation is achieved by means of gears 27, 28.
  • Roller 21 has a pattern with blades 31, which blades are shown in cross-section on an enlarged scale in Figure 4.
  • the surface of roller 22 is essentially smooth, whilst the cutting edge of the blades 31 extends virtually as far as the surface of the roller 22 at the location of the gap 29. Consequently, the desired cutting pattern in accordance with the blanks can be produced in the web of material 30.
  • pins 32 are arranged on the roller 22. Said pins have a shank 34 with a sharp point 35, as well as a head 36.
  • the pins 32 are all accommodated in blocks 37.
  • the head 36 is located in the bore 38 of relatively large diameter, whilst the shank 34 extends through the bore 39 of relatively small diameter.
  • the stop face 40 which marks the transition between the bores 38, 39, is such a distance away from the external surface of the block 37 (which external surface is coincident with the external surface of the roller 22 in its entirety) that the sharp point 35 just extends into a recess 41 in the roller 21.
  • the bore 38 is provided with an internal screw thread, such that the head 36 of the pin 32 can be fixed in place by means of the headless screw 42.
  • the blocks 37 are each accommodated in recesses 43 in the surface of the roller 22. They are fixed to the latter by means of bolts 44, which are screwed into holes 45 provided with a screw thread.
  • the pins 32 By virtue of this construction of the pins 32, the latter can be made very thin, as a result of which it is possible accurately to pick up and remove even thin strips of waste from the cut-out blanks.

Abstract

L'invention concerne une installation de cylindres servant à produire des plis dans une bande de matière, tel que du carton, et comportant deux cylindres rotatifs (1, 2). Chaque cylindre est monté à ses deux extrémités dans des paliers, et comporte des surfaces de cylindre qui permettent aux cylindres de rouler l'un par rapport à l'autre en laissant un espace (7) entre les surfaces de cylindre. L'un des cylindres comporte au moins une cannelure, et l'autre comporte au moins un sillon, les cylindres étant synchronisés de telle sorte qu'à l'emplacement de l'espace, chaque cannelure est opposée à un sillon. De multiples cannelures (11) parallèles sont prévues sur un cylindre, et de multiples sillons (13) parallèles correspondants sont prévus sur l'autre cylindre pour permettre de former de multiples plis parallèles dans la bande de matière; un angle arrondi peut être formé à l'endroit où se trouvent ces plis.
