Definitions

  • the present invention relates to a device for spreading adhesive films on fabrics, membranes or the like.
  • the dosage roller and the spreading roller have a length of 2-3 meters, while their diameter is approximately 260 mm.
  • the dosage roller and the spreading roller rotate in mutually opposite directions at different speeds: the dosage roller in fact rotates at a peripheral speed of approximately 0.5 m/min, while the spreading roller rotates faster, with a peripheral speed of approximately 20 m/min.
  • rollers are parallel and adjacent at a distance which, depending on the type of adhesive and on the thickness of the film to be obtained, varies between 1 and 20 hundredths of a millimeter.
  • Heated or cold liquid adhesive is distributed between them in a region that is substantially centered on their centerline and is delimited laterally by sealing spatulas.
  • the adhesive is calendered by them, forming a film that adheres to the spreading roller.
  • the dosage roller is adjacent to a side of the spreading roller, the presser roller being adjacent to its opposite side.
  • the fabric to be processed is calendered between the spreading roller and the presser roller so that the spreading roller spreads by calendering on one of its faces a film of the adhesive that it carries.
  • the aim of the present invention is to provide a device for spreading adhesive film on fabrics, membranes or the like that obviates the above-mentioned drawback, allowing to obtain a film of adhesive that is distributed uniformly over the entire region of the fabric that it affects.
  • an object of the invention is to provide a spreading device that can be adjusted depending on the type of adhesive to be distributed in film on a fabric or on a membrane being processed.
  • Another object of the invention is to provide a spreading device that is structurally simple and easy to use and can be manufactured with low costs.
  • a device for spreading adhesive films on fabrics, membranes or the like which comprises a frame that supports
  • the reference numeral 10 generally designates a device for spreading films 11 of adhesive 12 on fabrics 13, membranes or the like, which comprises a frame 14 that supports:
  • the spreading device 10 further comprises a counterpressure roller 19 for mating the film 11 deposited on the fabric 13 by the spreading roller 16.
  • the counterpressure roller 19 is arranged adjacent to the presser roller 17 to calender the fabric 13 spread with the film 11.
  • the spreading device 10 further comprises means for mutual inclination 20, which are adapted to incline with respect to each other the dosage roller 15 and the spreading roller 16.
  • the means 20 for mutual inclination can be actuated by actuation means in order to pass
  • the means for mutual inclination 20 comprise first means 21 for moving a first end 22 of the dosage roller 15 along a direction C that is substantially perpendicular to a reference plane D that is formed by the plane of arrangement shared by the first axis of rotation A and by the second axis of rotation B, in the first configuration.
  • the means for mutual inclination 20 comprise, together with, or as an alternative to, the first movement means 21, second means 23 for moving a first end 24 of the spreading roller 16 along the direction C that is substantially perpendicular to the reference plane D.
  • first end 22 of the dosage roller 15 is the end that lies opposite the first end 24 of the spreading roller 16, thus a second end 25 of the dosage roller 15 that lies opposite the first end 22 is adjacent to the first end 24 of the spreading roller 16.
  • the respective first axis A and second axis B of rotation are mutually inclined in an X-shaped configuration.
  • the mutual inclination means 20 comprise linear actuators 26 and extensible brackets 27, which are composed of
  • the fork-like slider 29 is coupled slidingly with the articulated guide 28 and at least one of the linear actuators 26 is connected to the articulated guide 28 and to the fork-like slider 29 for the movement of the latter along the direction C, substantially at right angles to the reference plane D.
  • the mutual inclination means 20 conveniently comprise means for mating the presser roller 17 with the spreading roller 16 which are designed to maintain their parallel arrangement during the inclination of the spreading roller 16.
  • the presser roller 117 rotates in the same direction as the spreading roller 116.
  • the fabric 113 is guided by a guiding roller 119 so as to partially wrap around the presser roller 117, which drives it between itself and the spreading roller 116 to receive the film 111 of adhesive 112 from it.
  • the operation of the spreading device 10 according to the invention is as follows.
  • the actuation means are preset to define a relative inclination of the first axis of rotation A of the dosage roller 15 with respect to the second axis of rotation B of the spreading roller 16; in this manner, if no adhesive is distributed between the dosage roller 15 and the spreading roller 16 their mutual distance increases as one moves away from their centerline, due to their mutual inclination.
  • the film 11 provided by the calendering of the adhesive 12 between the dosage roller 15 and the spreading roller 16 is substantially uniform.
  • the invention achieves the proposed aim and objects, by providing a device for spreading adhesive film on fabrics, membranes or the like that allows to obtain a film of adhesive that is distributed uniformly over the entire region of fabric that it affects.
  • the distance between the spreading roller and the dosage roller is in fact kept constant, substantially over their entire region affected by the adhesive, by combining the divarication that increases toward their centerline, due to the action of the calendered adhesive, with the decreasing spacing toward their centerline region, which is forced by the mutual inclination of the dosage and spreading rollers.
  • a spreading device can be adjusted according to the type of adhesive to be distributed in film form onto a fabric or membrane being processed.
  • the materials used may be any according to requirements and to the state of the art.
