Definitions

  • the invention relates to a device for producing a curved sail by means of a curved work surface, on which canvas sheets are placed and connected to one another to form the sail.
  • the invention has for its object to provide a device for producing a curved sail, which can be adjusted to any desired shape of the sail and is therefore not limited to a single, predetermined sail shape.
  • the invention has the advantages that a work surface has been created which allows an exact adaptation to any shape with regard to the curvature of a sail.
  • complex arithmetic work and a large number of measurements are avoided in order to arrive at a curved sail which not only has certain external dimensions, but which also has a predetermined, very specific curvature.
  • the sail production can be done much faster and cheaper, and it leads to very precisely cut and sewn sails. Due to the clever, constructive structure, a quick change from one type of sail to another is possible.
  • a drawing stick makes it easy and quick to mark the fore and leech of the sail in the arched state.
  • the frame 1 of length a of a device R for the production of sails is assembled from perforated angle profiles; lateral vertical struts 4 of height c protrude from a floor frame made of longitudinal profiles 2 and between these cross profiles 3 inserted like rungs. 50 ridge profiles 5 are attached to these by means of tabs which are adjustable in their inclination.
  • Coupling brackets 6 for additional devices are provided on the upper ends of the vertical struts 4 or on the ridge profiles 5.
  • a flexible sheet 7 is stretched between the ridge profiles 5, which in the selected embodiment consists of several individual sheets overlapping each other at the joints p. Bores 8 or the like.
  • Recesses for set screws 9 are provided in the sheet 7 - at longitudinal distances e and transverse distances f from one another.
  • the countersunk head 10 of each set screw 9 has a recess 11 for a polygonal key and rests in a correspondingly inclined collar 12 of the bore 8. Below the plate 7, a nut 14 with a washer 13 and lock nut 15 is attached to the set screw 9.
  • Each of the adjusting screws 9 passes through a threaded bore 16 of an angle iron 17, which is held at the upper end of an adjusting bracket 18 by a screw 19 (FIG. 4). That bracket 18 is fixed with its lower end 20 by screws 21 to one of the cross sections 3.
  • a lifting element 49 corresponding to those adjustment brackets 18 can be seen from a hydraulic cylinder 48 and lifting pistons 47 movable therein; By means of this lifting element 49 or its fastening head 46, the shape of the plate 7 can be changed in the manner corresponding below using the adjusting bracket 18.
  • the lengths h of the individual adjustment brackets 18 - with set screws 9 - of a cross section 3 are different on the one hand and can be changed on the other in order to hold the shaped sheet 7 bent downwards from a plane E (FIG. 2) or upwards (FIG. 3), which extends across the entire width b of the device R and rests on its surface 30 as shown in FIG. 5.
  • the U-shaped curved coupling bracket 6 is held on one leg 25 by nuts 27 in a holder 28 so that the other leg 26 engages over the longitudinal edge 29 of the shaped plate 7.
  • This drawing stick 31 serves to mark and cut off the sail fabric sheets S.
  • Each of the sail fabric sheets S is placed on the surface 30 of the sheet metal 7, which has been previously adjusted according to the desired sail shape.
  • the adjusting brackets 18 and the lifting elements 49 are changed in the manner shown in FIGS. 2 and 3 with regard to their length h and / or their articulation point 21.
  • the axes of the set screws 9 or fastening heads 46 create acute angles i above the shaped sheet 7 (FIG. 2) or angles k below the shaped sheet (FIG. 3).
  • the sail fabric sheets S are cut off and then glued or welded together, and the blockages and slatted pockets glued in.
  • the overall size of the sail to be produced is drawn and cut to size using a long drawing stick 31 a.
