No. 556,069 Claims priority, application France, June 17, 1965,
  • a glue-coating machine having a glue-applying cylinder on which the material to be coated is fed, a rotary doctor cylinder being operatively associated with the glueapplying cylinder with a narrow gap between the two cylinders which regulates the quantity of glue applied to the material, the glue being supplied to the glue-applying cylinder ahead of the doctor cylinder.
  • the spacing between the axes of the two cylinders is automatically adjusted to thereby adjust the thickness of film of the coating substance in the gap between the cylinders.
  • first mechanism producing a signal related to the speed of progression of the material fed over the glue-applying cylinder
  • second mechanism producing a second signal related to the spacing between the axes of the two cylinders
  • a device for receiving the signals produced by the first and second mechanisms and for combining the signals and controlling the spacing between the cylinders in accordance with the combined signals.
  • Thickness of the film of glue covering the glue-applying cylinder is the Thickness of the film of glue covering the glue-applying cylinder.
  • said thickness of the film of glue is governed by:
  • centrifugal force which has a tendency to destroy said uniformity by forming annular bulges which may in fact be broken whereupon glue may be projected out- 'Wardly;
  • Centrifugal force depends in its turn on the speed of rotation of said cylinders and it is consequently related to the speed of progression of the cardboard or the like material to be coated.
  • the amount of glue transferred increases even if the thickness of the film of glue remains constant; this leads consequently to an increased expenditure of glue which does not improve the grade of the finished product and slows down its drying.
  • the present invention has as an object to provide an automatic adjustment of the thickness of the filrn of glue in a manner such that the transfer of the glue whatever may be the speed of progression of the cardboard is welldefined and assumes a constant value if required, this being obtained by subjecting the spacing between the axes of the cooperating cylinders to the action of two supplies of information governed respectively by the speed of progression of the cardboard or the like article to be coated and by the spacing between said cylinder axes.
  • the direction of the automatic correction is such that the thickness of the film decreases when the speed of progression increases.
  • FIG. 1 is a diagrammatic illustration of the principal components of a machine adapted to size a strip of corrugated cardboard of the so-called single surface type.
  • FIG. 2 is a perspective View of a control mechanism for such a machine.
  • FIG. 3 is a diagram illustrating the operation of said mechanism.
  • the coating machine includes, as illustrated in FIG. 1, a glue-applying cylinder 1, a doctor cylinder 2 means for feeding glue, size or varnish as provided in the case illustrated by immersion of the cylinder 1 in the vat 3 and a presser cylinder 4.
  • An adjustably positioned cylinder 5 defines the length of the are 6 over which the single surface cardboard 7 is in contact with the glue-applying cylinder 1.
  • the glue-applying cylinder 1 serves for transferring glue onto the article to be coated constituted by the strip of cardboard 7.
  • the doctor cylinder 2 adjusts the thickness of the film of glue in accordance with the adjustment of the spacing between its axis and that of the above mentioned cylinder 1.
  • the glue is fed, in the case illustrated, by immersion of the glue-applying cylinder 1 in the vat 3 in which the level of the glue is generally held at a constant height.
  • the glue may be fed however as well by means of a jet projected between the two cylinders 1 and 2 in which case the vat 3 serves only for recovering the glue and operates as a dry casing in association with an external pump.
  • the adjustment of the thickness of the film of glue is automatic as provided by way of example through an adjusting system including the following elements (FIG. 2):
  • An auxiliary motor 8 associated with a speed reducer and controlling two bell cranks 9 carrying the shaft of the doctor cylinder 2;
  • a control voltage supply constituted by a tachometric dynamo 10 generating a voltage controlled by the speed of progression of the cardboard; a further supply of feedback voltage opposing the control voltage is regulated by the modifications in the spacing produced between the axes of the cylinders 1 and 2 by the auxiliary motor 8, the last-mentioned supply being constituted by a potentiometer 12 fed by a stabilized voltage controlled by the relative shifting between the glue-applying cylinder 1 and the doctor cylinder 2;
  • An electronic system 13 (FIG. 3) which receives the control and feed-back voltages and compares them, said system having a tendency to eliminate the difference between said voltages by shifting the doctor cylinder in the desired direction as provided by the auxiliary motor 8 controlled by the rectifier amplifiers 14a and 1412, the relays 15a and 15b and the reversing switch 16.
  • the automatic adjustment of the spacing between the cylinders 1 and 2 is ensured by the fact that the auxiliary motor 8 drives as illustrated in FIG. 2, the sunwheel 19 of the planetary gear system 27 through the agency of the intermediate pinions 17 and 18, the inner sunwheel 29 and the planet pinions.
  • the outer sunwheel 19 driven by the planet pinions meshes with a pinion 21 driving a shaft 22 carrying eccentric members 23 adapted to shift the levers 9, the angular position of which, defines the value of the spacing between the axes of the two cylinders 1 and 2, which value is continuously given out by a vernier 24.
  • the control of the spacing between said axes includes the above-mentioned sun and planet gear 27 having a double input, of which one input is constituted by a planet carrier arm 28 driven by the handcontrolled arrangement while the other input is constituted by the above mentioned inner sunwheel 29 driven by the auxiliary motor 8.
  • the shaft of the hand-controlled arrangement 25 carries furthermore a self-locking system preventing said shaft from rotating in either direction unless it is driven by the hand controlled arrangement.
  • the control mechanism described shows a well-defined response curve so that it is advisable, while retaining the shape of said curve, to shift it forwardly or rearwardly 40 in accordance with the values of certain parameters depending on the features of the cardboard and glue which are being used.
  • an auxiliary manually adjustable potentiometer is inserted in series with the main potentiometer 12. Such an auxiliary potentiometer provides the auxiliary advantage of furthering the gauging of the electronic system.
  • a machine for coating glue and the like coating substance over a sheet of material chiefly the crests of the outer corrugations of a sheet of corrugated cardboard carrying a covering surface only on the side opposed to said crests, prior to the application of the second covering surface over said crests
  • said machine comprising a glue-applying cylinder over a predetermined arc of which the material to be coated is fed, a rotary doctor cylinder operatively associated with said glue-applying cylinder ahead of said are, with a narrow gap between the two cylinders, means for feeding the coating substance to the glue-applying cylinder ahead of the doctor cylinder and means for adjusting automatically the spacing between the axes of said two cylinders to thereby adjust the thickness of hte film of coating substance in the gap between the cylinders, the latter said means including a first mechanism for producing a signal related to the speed of progression of the material fed over the glue-applying cylinder, a second mechanism for producing a second signal related to the spacing between the axes of
