Definitions

  • the invention relates to a method and a device for manufacturing a calibrated cardboard tube with very low surface roughness and high dimensional stability.
  • This type of machine comprises a fixed cylindrical mandrel on which are wound in a helix one or more strips previously glued, with the exception of the first, and which make determined angles with the axis of said mandrel, the formed tube being driven. in rotation and simultaneously in longitudinal translation, by an endless belt making a dead turn around said formed tube.
  • Each cardboard tube thus continuously produced is then cut during its formation into unitary tubes, in a cutting or cutting-off station.
  • Patent FR 1563024 and its additions to the name of the applicant do not solve all of these problems.
  • the aforementioned patent recommends a method of manufacturing a tube which is remarkable in that on a raw tube, made of in a conventional manner, there is wound up a glued strip of a compressible material of low density, such as felt cardboard, intended to form the penultimate fold, then a strip of dense material, intended to form the last fold, sand and coat the outer surface of said last ply with a thermosetting resin and, finally, after cutting and steaming, passing each section of tube through a heated die, so as to simultaneously obtain the calibration, by crushing from the front -last compressible fold, and polymerization of the resin coating.
  • a compressible material of low density such as felt cardboard
  • the sanding operation can be avoided by a preparation and a particular bonding of the last ply
  • the second addition describes other hot compression means than the die described in the patent. main and further specifies a possibility of eliminating the external coating of resin using a last porous ply and bonded to the penultimate ply by means of a thermosetting resin.
  • At least the penultimate ply is chamfered in parallel on its two longitudinal edges, so that the chamfers of two consecutive turns of this ply overlap.
  • the edge of the last fold opposite to the direction of advancement of the tube is in a known manner chamfered so that this edge is covered by the straight edge of the next turn.
  • the method according to the invention recommends a first narrow sanding of the outside surface of the raw tube, intended 4 to remove the edge formed by the clear edge of the last ply, followed by a second wider sanding intended to felect the material of said last ply.
  • the last coating is carried out by a simultaneous double spraying, on the one hand of the resin and, on the other hand, of a catalyst.
  • the invention also relates to a device for the implementation of this method comprising in particular a spiraling machine for the manufacture of continuous tubes, a station for sanding the tube, a resin coating station, a cutting station, a drying of the sections and a transverse compression station of said sections, a remarkable device in that it further comprises, downstream of the compression station, a station for coating the sections, followed by a flexible polishing or sanding station.
  • the section coating station is preceded by a section sanding station.
  • the tube sanding station has a first narrow sanding means for the tube, followed by another wider sanding means, while the tube coating station has at least two coating means per bath and / or spray.
  • the invention obviously relates to a tube manufactured according to the above-mentioned process and / or by means of its implementation device.
  • FIG. 1 we can see a raw tube 1 which is manufactured in a known manner by a spiraling machine 2 intended to wind helically a plurality of strips glued around a mandrel 3, the raw tube being driven in translation according to arrow F and in rotation by an endless belt device 4.
  • the spiring machine 2 is equipped with a cutting station 5 intended to form several sections of tube such as 1 1 in FIGS. 1,4 and 5,6.
  • the first "folds" of the tube formed by the first coiled bands 6a to 6i are here with almost contiguous turns (Figure 3) while the antepenultimate band 7a and the penultimate band 7b intended to constitute the corresponding plies are chamfered on their two longitudinal edges so that the chamfers 7'a and 7'b ( Figure 3) of two consecutive turns of each of these plies overlap.
  • One or more of the bands 6a to 6i could also be chamfered like the bands 7a and 7b.
  • edge 8a of the strip 8 forming the last fold and which is opposite to the direction F of the advancement is chamfered on its face facing outwards so that this edge 8a is covered by the straight edge 8b of the next turn ( Figures 1 to 3).
  • the first folds of the tube formed by the strips 6a to 6i are for example made of kraft cardboard while the last fold, the penultimate and the antepenultimate are made by Lar: respectively 8, 7b, 7a of a long fiber and dense material such as paper d 'impregnation, the strip 8 being slightly wider.
  • the strips 7a and 7b are further impregnated, before winding, with a thermosetting resin, such as a phenolic resin, by means for example of devices provided on the reels on which said strips are stored and unwound.
  • a thermosetting resin such as a phenolic resin
  • the embodiment described comprises only two impregnated strips 7a and 7b, but preferably this number is higher.
  • a sanding station 9 consisting of a first means 9a with a narrow sanding belt and a second means 9b with a wider sanding belt.
  • the first means 9a is intended to eliminate the edge formed by the frank edge 8b of the outer ply while the means 9b is intended to felt the material of said last ply.
  • the sanding station is followed by a coating station 10, constituted here by two tanks 10a and 10b filled with a mixture containing a phenolic resin.
  • the number of tanks may of course be different, as may the nature of the coating station (spraying for example).
  • each section is dried in depth before being worked in a die apparatus shown in FIG. 4.
  • the apparatus of FIG. 4 comprises a frame 11 provided with a hydraulic cylinder 12 and coaxially a die 13.
  • the rod 14 of the actuator 12 is provided with a head 15 intended to push one of the ends of each section of tube introduced into a cylindrical core 16 of the die 13;
  • the cylindrical core 16 is surrounded by a sealed envelope 17 in which a heated fluid circulates, so that the temperature of the core 16 of the die corresponds to the polymerization temperature of the resin used in station 10 in FIG. 1.
  • This sanding station includes a flexible abrasive belt 18, the tension of which is adjustable and which is applied to the working section arranged on motorized support rollers 19.
  • the rollers 19 are also orientable with respect to the axis of the tube section so that they can impart to the latter a rotational movement and a translational movement.
  • Sanding is usually done in a slow back and forth, so as to cross the steps.
  • This sanding is to improve the bonding of the last coating while also improving the surface condition.
  • a spray gun 21 is arranged for example on a rod 22 parallel to the axis of the sections and on which it is moved in translation so as to be able to come and go at a constant speed, so as to homogenize and regularize the coating.
  • the gun 21 is supplied with a thermosetting resin, for example polyester.
  • a catalyst is mixed with said resin and preferably, two guns or a two-headed gun are used so as to spray the resin and the catalyst at the same time.
  • This spraying is generally done on a round trip of the gun (to cross the steps).
  • the sections thus coated are then dried in ambient air or in an oven, each section being arranged in a vertical position.
  • the buffing is carried out after closing the ends of the section and under spraying with water so as to cool the section and entrain the dust.
  • the last coating makes it possible to obtain a surface of homogeneous and permanent hardness and low roughness, only thanks to the fact that the preliminary operations described above already make it possible to obtain a hard undercoat on a tube or section of tube. whose geometry is also stabilized as already specified.
