Definitions

  • the present invention concerns a method for making a wooden boat, intended for both professional and leisure use.
  • the present invention is applied to a method for the production, with characteristics of repeatability on a small or medium scale, of boats made of wood or wood-based composite material.
  • the method consists of making a shell formed by several layers of thin lamellar wood elements, glued to each other and subjected to pressure. The thickness and the size of the lamellar wood elements depend on the sizes and the shape of the boat. Construction according to this method is achieved through the deposition of wooden elements to cover a forming mold, which also constitutes the supporting structure of the boat. Deposition is achieved by covering the forming mold with several layers of planking.
  • each single wooden element must be shaped in a specific manner so that it fits together with the adjacent elements. This shaping is substantially performed on each single element and before its deposition.
  • the supporting structure of the boat also used as a forming mold of a pre-defined shape, at the end of construction constitutes an integral part of the boat itself. This characteristic renders the forming mold unusable for the production of other boats.
  • One purpose of the present invention is to achieve a method for the production of a wooden boat, for both leisure and professional use, which reduces production time and costs, also through a reduction in the wooden elements discarded during production.
  • a further purpose is to considerably reduce the probability of committing errors during the assembly step of the individual components.
  • Another purpose is to also allow the assembly of the wooden elements by personnel not particularly qualified in the field, contributing therefore to further reduce production costs.
  • a method according to the present invention can be used to make a boat using a plurality of wooden elements, able to form the external planking of the boat, and a forming mold.
  • the method according to the present invention comprises a first step in which, by using electronic processing means, at least the external shape of the boat is defined.
  • the method according to the present invention also comprises a second step which defines, always using said electronic processing means, both the definitive shape of every single wooden element and its reciprocal position in the disposition able to form said external planking substantially in conformity with the external shape defined in the first step.
  • the corresponding flat shape is defined.
  • corresponding flat shape we mean the projection on a plane of each wooden element, whose definitive shape is at least partly curved.
  • a determinate identification is assigned to each of the wooden elements that form the external planking, using the above-mentioned electronic processing means.
  • the method according to the present invention also comprises a third step in which the wooden elements are made in their definitive form. This production is achieved starting from the corresponding flat shape, defined during the previous second step of the method according to the present invention.
  • the method according to the present invention also comprises a fourth step in which the wooden elements are disposed on a forming mold so as to form the planking according to the external shape of the boat defined in the first step.
  • the method according to the present invention through the use of said ordered and sequential disposition of the wooden elements, allows both to reduce the deposition times and also to reduce the probability of committing positioning errors of said wooden elements, as well as a repeatable production process.
  • the method according to the present invention also comprises a fifth step in which said forming mold is separated from the external planking.
  • the forming mold does not form a single body with the boat, as happens with other production methods for wooden boats, and can be re-used for making another boat.
  • the boat that is obtained has no internal transverse reinforcement structures and the internal walls are smooth.
  • said external planking consists of a plurality of layers each made with said wooden elements.
  • said external planking comprises at least three layers.
  • a first layer of planking is made by arranging the wooden elements on the forming mold according to a direction substantially parallel to the longitudinal direction of the boat.
  • a second layer of planking is made by arranging the wooden elements on the mold with a pre-defined inclination, set intermediate between the direction according to which the wooden elements of the first layer are disposed and the direction orthogonal thereto.
  • a third layer of planking is made by arranging the wooden elements on the forming mold with an opposite inclination with respect to the direction according to which the wooden elements of the second layer are disposed.
  • the figures relating to the shapes of the wooden elements are advantageously positioned inside figures that identify the panels intended for the production of the wooden elements. This positioning is performed so as to minimize the empty and unusable areas on the shapes that identify said panels, allowing to reduce the waste produced during the production of the wooden elements.

  • a forming mold 30 is also defined, able to be used in the deposition of the wooden elements 22 in order to make the planking 23 of the boat 20 and consisting of templates 32 corresponding to a predefined number of transverse sections of the boat 20.
  • suitable spacers 34 are defined, able to be interposed between said templates 32.
  • the second step is also performed with the aid of said programs for electronic processors of the three-dimensional CAD type, which simplify and quicken the definition of the shapes of the wooden elements 22 and allow an automatic assignment of their numerical identification and their ordered sequence of use.

  • a third layer of planking 26 is disposed according to a direction with an inclination opposite to that of the second layer of planking 25.
  • a corresponding flat shape is defined for each of the wooden elements 22.
  • the flat shape characterized by a section 28 with two rectilinear sides 36 and two curvilinear sides 38, facilitates the use and the laying of the wooden elements 22 on the forming mold 30.

  • the templates 32 of the forming mold 30 are disposed, at distances corresponding to predefined sections of the boat, and are located so as to give shape to the boat 20 in an upside-down position (fig. 1).
  • the spacers 34 are disposed between the templates 32 and joined thereto so as to keep the templates 32 parallel and give rigidity to the forming mold 30.
  • seatings 40 are defined on each template 32, able to house known structural elements of the boat 20, and not represented in the drawings, such as shelves, battens, the keel and the stem.
  • the wooden elements 22 are disposed on the seatings 40 of the templates 32, overlapping and laminated with resins, for example of the epoxy type, and able to form said structural elements.
  • the wooden elements 32 are curved and kept in shape, adhering to the forming mold 30, by means of clamps 42 (fig. 2) until the end of the gluing action.
  • the shelves in particular, once shaped on the forming mold 30 (fig. 2), are separated therefrom and positioned after the formation of the planking 23 of the boat, in order to allow the easy separation of the forming mold 30 and the boat 20.
  • the fourth step of the method also comprises (fig. 4) the formation of the first layer of planking 24, by laying the wooden elements 22 in the transverse direction of the boat 20.
  • the laying is regulated by the ordered sequence of use defined in said second step.
  • the wooden elements 22, consist of planks, preferably of cedar wood, which have said circular section 28 coupling (fig. 4) and formed by the respective curvilinear sides 38, able to increase the reciprocal gluing surface and to allow a reciprocal inclination of the wooden elements 22, so as to adapt their disposition on the curvilinear profile of the templates 32 of the forming mold 30.
  • the wooden elements 22 are therefore glued to one another and therefore to the templates 32 of the forming mold 30 and subsequently their ends are fixed with screws to the profiles of said templates 32.
  • the screws are removed at the end of the laying of the first layer of planking 24 and in any case once the gluing action of the wooden elements 22 has ended.
  • the boat 20 has assumed its external shape.
  • the fourth step also comprises the formation of the second layer of planking 25, inclined with respect to the direction of the first layer of planking 24 (fig. 5).
  • the wooden elements 22 that constitute the second layer of planking 25, advantageously treated with resins for example of the epoxy type are fixed to the first layer of planking 24 by means of stainless steel staples.
  • the wooden elements are then made to adhere to the elements of the first layer of planking 24 with a vacuum technique by suction of the air present on the gluing surfaces.
  • the disposition of the wooden elements 22 that make up the second layer of planking 25 is performed, according to the sequence of use defined in the second step, starting from the center of the boat 20.
  • the length of the wooden elements 22 that make up the second layer of planking 25 is longer at the center than at the ends of the boat 20. In this way possible angular positioning errors are reduced to a minimum.
  • marking signs are indicated at pre-defined distances on pre-determined wooden elements 22 that make up the keel and the main batten of the boat 20; the signs are able to indicate the inclination according to which the wooden elements 22 that constitute the second layer of planking 25 are to be positioned.
  • the fourth step ends with the formation of the third layer of planking 26.
  • the laying of the third layer of planking 26 is performed in a manner identical to the laying of the second layer of planking 25.
