Definitions

  • the invention concerns a method and apparatus to make sails by means of a film of windproof plastic material, which is made to emerge from a feed assembly and to pass, while still in a deformable state, over a mold arranged in a stationary position but able to change its profile to shape the film as the latter advances.
  • wires of extremely resistant plastic material are deposited on the already shaped film, along the load lines of the sail .
  • the state of the art includes a method to make sails in which a mold is prepared, substantially as big as the sail which is to be made, and having a convex surface suitably shaped to assume the three-dimensional shape of the sail to be made.
  • a first sheet of flexible material is arranged on the three-dimensional mold, to define an outer layer of the sail, which is exposed to the wind; then, reinforcement threads are applied and glued to this outer layer, from one edge to the other and from one angle of the first sheet to the other.
  • a second flexible sheet is applied which defines a second outer layer of the sail. Then, the two sheets and the layer of threads are laminated together,
  • This conventional method has some disadvantages, however.
  • Another disadvantage of this conventional method is that it is necessary to prepare costly and complex equipment to spread the sheets and threads above the extremely extensive surface of the mold, and also to use highly specialized staff who can literally "fly" above the mold to control that the various components are correctly laid and reciprocally glued together.
  • One purpose of the invention is to perfect a method and an associated apparatus to make sails of a three-dimensional type without needing to prepare a mold with a surface as big as the sail to be made.
  • the method according to the invention comprises at least the following steps: a film of flexible plastic material is extracted from a feed assembly while the film is still in a defor able state, that is, it has not yet assumed a defined shape; downstream of the feed assembly a forming unit is arranged in a stationary position, transverse to the longitudinal axis of the advancing film and comprising a mold able to assume a variable transverse profile; the film is made to advance with respect to the forming unit, making it adhere to the mold while the latter temporarily has a particular profile; the film is cooled so that, in the zone where it is in contact with the mold, it assumes the temporary profile of the mold.
  • the method according to the invention advantageously comprises a further step to reinforce the already formed film, by means of reinforcement elements which are arranged at least along preferential lines, for example along the lines of greatest load of the sail to be made.
  • a reinforcement unit also arranged in a stationary position, transverse to the direction of feed of the film.
  • the reinforcement unit comprises laying means able to lay on the film reinforcement elements made of substantially unstretchable plastic material, and contrasting means able to assume the transverse profile which the film has when it is passing in correspondence with the reinforcement unit.
  • the assembly to feed the film can comprise an extruder or a heating device arranged downstream of one or more reels of film, which can be glued to each other, along their edges, to form a single film with the desired width.
  • Fig. 1 is a prospective view of an apparatus according to the invention
  • Fig. 2 is a first variant of the feed assembly of the apparatus in Fig . 1
  • Fig. 3 is a second variant of the feed assembly of the apparatus in Fig. 1;
  • Fig. 4 is a transverse view of a first working unit of the apparatus in Fig. 1;
  • Fig. 5 is a transverse view of a second working unit of the apparatus in Fig. 1;
  • Fig. 6 is a plane view of the apparatus in Fig. 1;
  • Fig. 7 is a side view, partly in section, of the apparatus in Fig. 1.
  • an apparatus 10 to make sails according to the invention comprises a feed assembly 11 from which a film 12 of plastic material is able to emerge.
  • the film 12 is windproof and easily deformed and shaped, like a polymer, a polyester, such as for example the one known commercially as "Mylar", or other conventional materials, already used in the sailing sector, or even not.
  • the thickness of the film 12 can vary, according to the type of sail 13 to be made (Fig. 6) , from some tenths of a millimetre to several millimetres.
  • the width of the film 12 is greater than that of the sail 13 to be made, so that, for very large sails, the width can reach and exceed 30 metres.
  • the feed assembly 11 can consist of an extruder 14 (Fig. 1) , which comprises one or more conventional extrusion heads 15, arranged adjacent.
  • the different extrusion heads 15 are advantageously modular, so that they are located adjacent in a suitable number, according to the size of the sail 13 to be made.
  • the feed assembly 11 comprises a reel 16 of film 12 arranged upstream of a heating device 17 which is able to heat the film 12 to make it deformable.
  • a plurality of reels 16 can be provided (Fig. 3), arranged so that, as they unwind, the individual films are positioned above the adjacent films, along their edges, and are joined one to the other, in any conventional fashion, to form the film 12 of the desired widt . While it is still in its deformable stage and has not yet assumed its definitive shape, the film 12 is made to pass through a forming unit 20 (Figs. 1 and 4), in contact with ah upper surface 21 of a first mold 22.
  • the mold 22 is made of flexible material, such as rubber for example, and comprises a plurality of adjacent segments 23, each of which is associated with a corresponding actuator 25, for example of the pneumatic or fluid-dynamic type, so that it is able to be selectively raised or lowered with respect to a nominal horizontal plane X, so that the mold 22 can assume any curved condition, either concave or convex with respect to the horizontal plane X.
  • the latter is provided inside with a cavity 26, in which a depression is created in any conventional manner, and with a plurality of little holes 28 which make the cavity 26 communicate with the upper surface 21.
  • drawing means 30 consisting for example of a plurality of pairs of rollers, facing each other and motorized, which collaborate with the lateral edges 12a, 12b of the film 12 to make it advance at a substantially constant speed with respect to the mold 22.
  • the curve of the mold 22 is modified, by working in a coordinated fashion on the actuators 25, to make every transverse section of the sail 13 assume the desired form and rounded shape.
  • the actuators 25 are controlled by a processor 31 which, from a stationary sensor 32 (Fig. 6) of a conventional type, receives a signal indicating the position of the film 12 as it advances .
  • a unit 40 to reinforce the sail 13 being formed Downstream of the forming unit 20, and possibly also of the first drawing means 30, there is a unit 40 to reinforce the sail 13 being formed; said unit 40 is able to spread a plurality of reinforcement elements 41 on the film 12, consisting for example of wires or strands of plastic material, very resistant and substantially unstretchable, such as carbon fibre, aramidic fibre like Kevlar, high molecular weight polyethylene such as Spectra, liquid crystal polymers like Vectra, PBO or suchlike.
  • the reinforcement unit 40 is kept advantageously stationary in a set position, even though the distance from the forming unit 20 can be variable according to the production cycle.
  • Each reinforcement element 41 is able to be laid by a laying device 42 (Figs.
  • the reinforcement elements 41 can be wires, tapes or elements extruded during the step when they are laid on the film 12.
  • a contrasting device 48 is arranged below the film 12 in correspondence with the laying devices 42 to define a surface on which the film 12 can rest.
