    Abstract: The invention relates to a winding machine for winding ribbon or filament material (203) around an elongated object (292), e.g. the spar of a wind turbine blade. According to the invention the winding machine has an opening (204,304) in a structural part which at least partly encircles the object during the winding process. The opening (204, 304) allows easy positioning o the winding machine or the object (292) since the object can pass through the opening along a radial direction, i.e. a direction perpendicular to the elongated extension of the object. The winding machine includes a carrousel which includes a movable element configured to be guided by a guiding support Accordingly, the carrousel is constructed as an open structure in contrast to a closed structure such a closed ring.

    Abstract: A method and an apparatus for producing a multiaxial fabric are disclosed. According to the method at least one yarn is arranged helically about at least two conveyor portions, thereby providing a weft having a first weft portion having yarns arranged at an angle, θ, with respect to the conveying direction of the conveyor portions, and a second weft portion having yarns arranged at an angle, -θ, with respect to the conveying direction of the conveyor portions. Centre sections of the first weft portion and the second weft portion are then fixated to each other, e.g. by stitching and/or by applying a resin to the centre sections. Side portions of the weft are then cut, thereby separating the first weft portion from the second weft portion. Finally, rim sections of the first weft portion are fixated to rim sections of the second weft portion, e.g. by stitching and/or by applying a resin to the rim sections. The combination of helically winding the yarn about the conveyor portions, fixating the centre sections to each other, cutting the side section and fixating the rim sections to each other ensures that it is not necessary to cut away material, and the material used for making the weft is therefore utilised to the greatest possible extent.

    Abstract: The present invention relates to a method of manufacturing a laminated composite item(l). The method may comprise the step of winding successive overlapping helical convolutions of resin impregnated tape (2) onto a mandrel (3) while advancing the tape back and forth along the mandrel. Sections of the tape being wound onto the mandrel near an end of the mandrel are folded to obtain an end surface of the composite item which is substantially-perpendicular to a longitudinal axis of the composite item. The present invention further relates to an alternative method of manufacturing a laminated composite item. This method comprises the steps of winding successive overlapping helical convolutions of resin impregnated first tape onto a mandrel while advancing the tape back and forth along the mandrel, and winding layers of a second tape having a straight edge (8a) and a serrated edge (8b) onto an end section of the mandrel to obtain an end surface of the composite item which is substantially perpendicular to a longitudinal axis of the composite item. The invention further relates to apparatuses for carrying out such methods and for wind turbine blade spars manufactured by such methods or by use of such apparatuses.

    Abstract: The present invention provides an apparatus and a method for preparing a pre-form (2) comprising at least one layer of fibre tows being at least partly fixed by a resin. The apparatus comprises a work surface (3), a fibre tow distribution device (4), a fibre tow retention device (5), and a manipulation, device (7b) which is adapted to move the fibre tow distribution device relative to the fibre tow retention device. The apparatus is arranged so that free ends of the fibre tows can be delivered from the fibre tow distribution device to the fibre tow retention device, and the fibre tow retention device is adapted for retention of the free ends so that mutual movement of the fibre tow distribution device and the fibre tow retention device away from each other causes drawing of the fibre tows through distribution passage and distribution hereof onto the work surface.
