  • gears R1 and R2 which have the function of meshing with gears with which the supports of the winding rods are equipped, as will be clarified later on, in order to impart a movement of rotation upon the rods A about their axis when these are supported by the supports 2OA and 2OB or 21A and 21 B in the position of maximum height (already referred to as engagement height) awaiting rod change (Figure 5A) in order to bestow on said rods the same peripheral velocity as that of the winding roller 11.

  • the supports 2OA and 21A are arranged within the respective sides 5, whilst the supports 2OB and 21 B are arranged on the outside of the respective sides.
  • Each of the supports 2OA, 2OB is set on a respective carriage 23, said carriages being substantially symmetrical and only one of them will be described in greater detail in what follows with reference to Figure 1 B.
  • the supports 2OB and 21 B are arranged, instead, on carriages 25, which also are substantially symmetrical and only one of them will be described with reference to Figure 1C.

  • Each carriage 23 ( Figure 1 B) is able to slide along guides 27 fixed to the respective side 5. Said guides 27 are arranged on the internal face of the two sides 5.
  • the carriage 23 is mobile along the guides 27 in the direction of the double-headed arrow f23. The movement is controlled alternately by two different mechanisms.
  • the movement from the position furthest away from the winding roller 11 to the position of the roller itself is driven by a belt 29, to which the carriage is constrained, by means of an actuator (not illustrated), which drives one of the pulleys over which the belt 29 is run.
  • the movement in the opposite direction i.e., in the direction of recession away from the winding roller 11 , is obtained as a result of the gradual growth of a reel around the winding rod that is temporarily engaged to the respective support 2OA or 21A and in contact with the winding roller 11.
  • the reference number 31 designates a cylinder-rodless piston actuator, which pushes the carriage 23 towards the roller 11 in such a way that the reel, in the step of formation around the rod held by the support 21 A or 21 B, is pressed against the winding roller 11 to enable the latter to carry out winding, transmitting the motion of rotation to the reel.
  • f33 is controlled by a servo motor 35 through a belt 37, which transmits the motion to a pulley 39 of a linear actuator 41 , which has a bar 43 that can be extracted and retracted to cause the displacements according to f33 of the slide 33.
  • Constrained to the rod 43 is a cylinder-piston actuator 45, of which designated by the reference number 47 is the rod hinged to the support 21A or 21 B.
  • This double movement enables an effective grip of the winding rods and their effective gradual introduction into the area of winding after they have duly been brought into contact with the winding roller 11 to receive the leading end of the weblike material each time generated by cutting thereof, as will be described in greater detail in what follows with reference to an operating sequence.
  • the configuration of the carriage 25 that carries one or the other of the supports 2OB, 21 B is substantially equivalent to that of the carriage 23, as may be noted in the representation of Figure 1C, where one of the carriages 25 is illustrated in isolation with respect to the side 5 that supports it.
  • the reference 25A designates the slides that guide the carriage 25 on guides 51 fixed to the respective side 5 and equivalent to the guides 27.
  • Set on the carriage 25 is a slide 53, which is vertically mobile in the direction indicated by the arrow f53, the movement of which is controlled by a linear actuator 55 driven by a servo motor 57 by means of a belt 59 and a pulley 61.
  • the reference number 63 designates the extractable and retractable bar of the linear actuator 55, which is constrained at the top by a cylinder-piston actuator 65 equivalent to the cylinder-piston actuator 45 of the carriage 23.
  • the rod 67 of the cylinder-piston actuator 65 is constrained to the support 2OB or else 2OA. Up to this point the structure of the carriage 25 is substantially the same as that of the carriage 23.
  • an electric motor 71 at the output of which, by means of a joint 73, there is connected a reduction gear 75 ( Figure 1C).
  • This arrangement supplies motion to a respective gear 77 that is to mesh with the corresponding gear R1 or else R2 of the rod that is temporarily supported by one or by the other of the supports 2OA, 2OB.
  • the motor 71 thus provides the movement of rotation for the auxiliary operations on the winding rod A when this is not driven in rotation by the winding roller 11.
  • a cutting device located along the path of the weblike material N, upstream of the winding roller 11 is a cutting device designated as a whole by 91 and illustrated in isolation in Figure 3 and in the enlarged detail of Figure 3A.
  • the cutting device 91 comprises a pressurized- water nozzle 93 carried by a slide 95 having a reciprocating rectilinear movement in the direction indicated by f93, orthogonal to the direction of feed of the weblike material N along the path of advance through the machine.
  • the movement of the slide 95 and of the nozzle 93 carried thereby is controlled by a cylinder-rodless piston actuator 97 supported by a beam 99.
  • a sliding surface 101 Located underneath the path of the nozzle 93, and on the side opposite thereto with respect to the path of the weblike material, is a sliding surface 101 , along which the weblike material runs, said surface being interrupted by a groove 103, which is parallel to the path of the nozzle 93 and is located exactly underneath the latter.
  • Developing underneath this groove 103 are tanks 105 for collecting the water, which comes from the nozzle 93 and is ejected at a high pressure therefrom. In the tanks there may be arranged systems for extinguishing the kinetic energy of the jet of water.
  • Figure 5A illustrates a step in which a reel BA of weblike material N is being formed on a first winding rod A.
  • the winding rod is supported by the first pair of supports 2OA, 2OB.
  • the cylinder-rod less piston actuators 31 , 81 push the carriages 23, 25 and hence the reel BA against the winding roller 11 so that rotation of the latter causes feed of the weblike material and rotation of the reel BA and of its winding rod and consequently winding of the material around the rod.
  • the supports 2OA, 2OB are displaced towards a position for unloading, which is located at the opposite ends of the guides 5A with respect to the position in which the winding roller 11 is located.

  • the inclination of the cutting line T with respect to the direction of the machine, represented by the direction of feed fN of the weblike material, is such that the most advanced vertex V defined in the leading end NB comes into contact with the new rod, which has duly been lowered towards the winding roller 11 via retraction of the cylinder-piston actuators 45, 65, before the cutting T is completed.
  • the supports 21 A, 21 B are then gradually lowered, so as to keep the rod A (onto which the product is being wound) always in contact with the winding roller 11 , whilst the reel BB starts to grow in diameter until the shanks of the new winding rod rest on the resting and rolling guides 5A.
  • the supports 21 A, 21 B will then be further lowered in order to free the rod with the reel wound thereon, thus enabling it to be unloaded and allowing the supports to translate once again towards the area in which the winding roller is located.
