  • the machine according to the invention comprises a frame 11 which supports:
  • Three portions can be identified in the machine 10, of which one is innermost, indicated with 50, in which the fabric is processed, the above mentioned rollers and means being present therein, and two external portions 51 and 52, on opposite sides of the internal portion 50, in which means for aiding the operation of the previously-mentioned components are boxed, which are described below.
  • the distribution roller 12 comprises a body 16 with a tubular jacket 17 around the body 16.
  • the body is coupled to the frame 11 with respect to which it rotates about the axis A, and the jacket 17 rotates integrally with the body 16 and can be removed from it.
  • the jacket 17 is adapted to bear, on its outer surface, the glue to be deposited on the fabric.
  • the body 16 preferably has a cylindrical shape. However, in other versions, not shown, the body 16, and hence also the jacket 17, can have a conical shape.
  • the jacket 17 is preferably made of carbon steel, while the body 16 is preferably made of aluminum, especially heat-treated to ensure stability and resistance to wear.
  • the body 16 is internally hollow and on the inner surface electric resistance heaters are distributed for transmitting heat to the body 16 itself and therefore to the jacket 17.
  • the operating temperature at which the jacket 17 is used is preferably approximately 150°C.

  • the screw head 33 is indicated in Figure 1 .
  • a helical groove 47 which, when the jacket 17 is coupled with the body 16, acts as a coil for the passage of a cooling fluid, preferably air.
  • Figure 1 and Figure 2 show the machine 10 in the same perspective view and during an operation to substitute the jacket 17.
  • Figure 1 shows the jacket 17 mounted on the body 16
  • Figure 2 shows the jacket 17 just removed or about to be mounted, in the external portion 51 of the machine.
  • the body 16 When the machine 10 is inactive, for example for maintenance or to change the jacket 17, the body 16 is coupled in a cantilever fashion to the frame 11, where it is kept guided by bearings.
  • the machine 10 comprises means for translating 19 the jacket 17 along the axis A coupled with the body 16 and uncoupled, which in turn comprise parallel rails 22, which can be extracted in a drawer-like fashion, with a carriage 20 adapted to move the jacket 17 into and out of the machine.
  • the machine 10 according to the invention also comprises means for lifting 21 the rails 22 and the carriage 20.
  • Figure 5 shows the carriage 20 completely extracted from the machine 10.
  • the carriage 20 comprises idle wheels 23 which roll on the parallel rails 22.
  • the wheels 23 support a structure for resting the jacket 17, constituted by two lateral shoulders 24 that contain the jacket 17 itself and, between these, two contoured pans 25, in the front part and in the rear part, contoured with an upward-facing concavity, for resting the jacket 17 (as shown in Figure 2 ).
  • a handle 26 can be used.
  • the lifting means 21 comprise a screw gear reducer 27 below the rails 22, to be actuated manually using an handwheel 28 with a handle.
  • the reducer is indicated in Figure 1 .
  • the rails 22, the carriage 20 and the reducer 27 are conveniently installed in the external portion 51, from which the rails 22 and the carriage 20 can be extracted from the machine 10 for substitution of the jacket 17.
  • presence sensors 29 which detect the position of the carriage 20. These are installed at the rails 22: two of them 29a, 29b are installed in the external portion 51, and another one 29c is installed in the internal portion 50.
  • the sensor 29a is adapted to detect the presence of the carriage 20 when this is fully extracted from the external portion 51, by detecting the presence of a notch on the carriage.
  • the sensor 29b is adapted to detect the presence of the carriage 20 if it is lifted.
  • the sensor 29c in the internal portion 50 is adapted to detect the presence of the carriage 20 in the internal portion 50 of the machine.
  • the dosing means 15 comprise a doctor 30, preferably made of harmonic steel, which is provided with means for movement 31 toward or away from the distribution roller 12.
  • the doctor 30 is indicated in Figure 4 .
  • the sensor 29c that detects the presence of the carriage 20 in the internal portion 50 sends a signal to software controlling the machine that prevents the doctor 30 from approaching.
  • the software allows the doctor 30 to approach the distribution roller 12.
  • the means for movement 31 comprise two actuators, one per side of the machine, like the one shown in the view in Figure 3 , which are adapted to raise and lower a support 32 carrying the doctor 30, and two pneumatic pistons 46, one per side, which are adapted to rotate the support 32, which is hinged to the frame 11 about an axis parallel to the axis A.
  • the translation and rotation of the support 32 determine the approach of the doctor 30 to the distribution roller 12, in a controlled manner as a function of the thickness of the jacket 17 mounted on the body 16.
  • the support 32 also carries a reservoir for the glue, heated in order to maintain the glue at a (preferable) temperature of 150°C during use of the machine 10.
  • Figure 4 shows a cross-section of the machine 10, during its use.
  • the position of the pressing roller 14 is modified, in so doing calibrating the distance from the jacket 17 in order to ensure the right level of pressure.
  • the fabric 13 is made to pass between the pressing roller 14 and the distribution roller 12.
  • the pressing roller 14, which is conveniently rubberized, exerts a pressure on the surface of the jacket 17, causing the adhesion of the gluing points, which are in the matrix, on the fabric 13.
  • the fabric 13 is brought into contact with the cooling roller 34 which crystallizes the gluing points.
  • the jacket 17 is substituted for one with a different diameter and/or with a different matrix of impressions: this requires the cooling of the distribution roller 12, following which the jacket can be easily extracted on the carriage 20 toward the lateral external portion 51.
  • the doctor 30 is moved away from the distribution roller 12, in the position shown in Figures 1 and 2 .
  • the rails 22 with the carriage 20 are brought below the jacket 17, in the internal portion 50 of the machine.
  • the jacket 17 on the supporting structure is then made to translate outside with the carriage 20 and with the rails 22.
  • Another jacket 17 is positioned on the carriage 20, and this is made to translate vertically using the screw gear reducer 27, in order to obtain the centering of the new jacket 17 on the rotation axis A.
  • the jacket 17 is then made to translate toward the innermost portion 50 so as to fit over the body 16, according to a single angular position defined by the screw head 33.
  • the support 32 of the doctor 30 is made to translate and rotate using actuators 31 and pneumatic pistons 46, in order to bring the doctor 30 into contact with the jacket 17 of the distribution roller 12.
  • the body 16 is heated using the adapted heating elements and the heat is then transmitted to the jacket 17.
  • the thermal expansion coefficient of aluminum, of which the body 16 is made is approximately double that of the carbon steel of which the jacket 17 is made. This ensures that the expansion of the body 16 is greater than that of the jacket 17, thus creating a compression on the body and so ensuring the mechanical seal between the two and the transmission of temperature to the jacket 17, which is necessary in operating conditions.
  • the cooling can be carried out with the air system, in order to obtain the shrinkage of the materials in the shortest possible time.
