Definitions

  • the invention relates to a method and a device for producing a curved sail.
  • the inventor has set itself the goal of creating a method and a device of the type mentioned at the outset with which the known deficiencies are avoided and which not only allow complicated sail cuts to be produced in a simple manner, but also one To offer cost-effective adaptation of the sails to the very different wishes of customers.
  • a work surface reflecting the final shape of the sail is set, placed on these sail fabric sheets, then cut and connected to one another in the preselected sail shape, and that the size of the sail is then drawn off and cut using adjustable rulers.
  • a shape-changeable work surface designed to be adaptable to the final shape of the sail is used, which according to the invention is formed by a bendable shaped plate in a frame.
  • This shaped sheet is attached to - optionally telescopically - adjustable-length adjusting brackets or lifting elements acted upon by a medium, for example hydraulic cylinders. It can be from the both kept in a flat normal position and brought into a convex or concave shape.
  • This adjustable device has the considerable advantage that the sail fabric sheets can be brought into the desired shape and corrections can be made.
  • tear-off slats can be swiveled or the like fastened in the b-work surface, which on the one hand make it easier to cut the individual fabric panels and on the other hand make it possible to cut the sail made on the work surface exactly.
  • the mobility of the shaped sheet is supported according to the invention in that the adjusting brackets or lifting elements are detachably attached to the shaped sheet and / or on the frame and can be plugged in depending on the desired sheet shape.
  • the shaped plate can advantageously be connected at its longitudinal edges to the frame in the region of ridge profiles, which are optionally connected to the frame by inclinable members.
  • Coupling brackets are provided on the frame and / or on the ridge profiles for fastening and guiding the above-mentioned drawing slats or the like, which are preferably U-shaped and are pivotably supported on the frame with one of their legs. The other leg then picks up the drawing stick, which therefore sits on the leg overlapping the shaped plate so that it can be pivoted and locked.
  • the drawing stick - which has different lengths for the cutting of the individual fabric sheets on the one hand and the finished sail on the other hand, possibly even variable in length - at least one similar to the coupling bracket Assign clamps, with which the drawing stick can be fixed.
  • the shaped sheet can be composed of several individual sheets which overlap one another in the area of their joints and thus contribute to the flexibility of the work surface.
  • the described method and the device now make it possible to produce a large number of sail shapes with a single machine, to be precise in accordance with the respective material specifications. It is even possible to adapt the work surface to the spontaneously expressed wishes of the customer immediately before the start of the manufacturing process. If the apparatus of the invention controlled by hydraulic elements, the adjustment of the respective molded in an unusually short period of time can be carried out, e g-optionally from a control panel.
  • the frame 1 of the length a of a device R for the production of sails is assembled from perforated angle profiles; lateral vertical struts 4 of height c project from a floor frame made of Löng profiles 2 and between these cross bars 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 exemplary embodiment consists of several individual sheets overlapping each other at the joints p.
  • Bores 8 or dcl. Are in the sheet 7 - at longitudinal distances and transverse distances f from one another.
  • Recesses for set screws 9 are provided.
  • 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.
  • Each of the set screws 9 passes through a threaded bore 16 of an angle iron 17, which is located at the upper end of a set bracket 18 by a screw 19 (FIG. 4). That adjusting bracket 18 is interchangeably fixed with its lower end 20 by screws 21 on one of the over profiles 3.
  • the lengths h of the individual adjusting brackets 18 - with adjusting screws 9 - outer profile 3 are different on the one hand and changeable on the other in order to hold the shaped sheet 7 bent downward from a plane E (FIG. 2) or downward (FIG. 3), which extends over the entire width b of the device R and on whose surface 30, as shown in FIG.
  • the U-shaped coupling bracket 6 is cn one leg 25 by nuts 27 in a holder 28 so that the other leg 26 overlaps the longitudinal edge 29 of the sheet metal 7.
  • a short tear-off slat 31 of length m runs from a box-like profile bar, which is attached to a perforation 33 of the holding bracket 6 by means of a screw 34; the chains 35 are located in the inside of the profile bar 36.
  • This drawing stick 31 serves to mark and cut off the sail fabric sheets S.
  • Each of the sail cloth beans S is placed on the surface 30 of the shaped plate 7, which has previously been set according to the desired sail shape.
  • the adjusting bracket 18 or the lifting elements 49 are changed in the manner shown in FIGS. 2 and 3 with respect to their length h and / or their articulation point 21.
  • the intended cross-sectional line of the mold plate 7 form the axes of the screws 9 or mounting heads 46 above the mold top plate 7 angle i (Fig. 2), or (g Fi. 3) below the forming plate angle k.
  • the sail fabric sheets S which have not been rolled up in detail, are cut off and then glued or welded together, and the reinforcements and Latentoschen glued in. Then, using a long re blot 31a, the total size of the sail to be produced is bled and cut to size.
  • the long drawing solder 31a of the length n sits according to FIG. 7 by means of screws 34 cm coupling bracket 6 and is overlapped by an additional helmet bracket 40, which in turn is in a helmet.
  • tion 28 is fixed with a leg 41; the upper leg 42 receives an adjusting screw 43, the tip 44 of which presses against the tear tab 31a.
