The manufacturing line comprises a plurality of molds for forming wind turbine blades.

Abstract: The loading apparatus (1) for loading rolls (2) of fiber based sheet material to an application unit for the production of fiber-reinforced parts comprises a frame (4) on which a lift (5) is arranged displaceably in vertical direction and is adapted to carry at least one roll (2). The lift (5) comprises a swivel mechanism (6) arranged rotatably about a swivel axis (7) and comprising at least first grippers (18) adapted to releasably grip shaft ends (9) of a first roll (2a) and second grippers (19) adapted to releasably grip shaft ends (10) of a second roll (2b). A method of loading rolls is also disclosed.

Abstract: The present invention relates in general to a method of manufacturing fibre-reinforced parts for a wind power plant, such as a blade, in an open mould. More specifically the invention relates to a process step of applying at least one layer of gelcoat on a interior surface of said open mould prior to arranging at least one layer of material comprising fibre and to an arrangement that can be used in performing said method. The process step comprises to apply the gelcoat from a first end portion of the mould and to a second end portion of the mould and to cover the open mould from said first end portion to said second end portion gradually as gelcoat is applied. The arrangement comprises means for applying gelcoat to the interior surface of the mould (1) and a covering means (6) arranged to gradually cover the open mould (1) as gelcoat is applied.

Abstract: A method of and an apparatus for, manufacturing fibre-reinforced parts such as blades for wind power plants, whereby a number of layers (10) of material comprising fibre are arranged on a curved surface of an elongated open mould (1) so that some of the layers of material overlap at least partially. Each layer of material is positioned on the mould by means of a number of rollers (20) provided on a cart (70) being conveyed along the open mould. At least some of the rollers are displaced mutually during the conveyance of the cart so that the rollers substantially follow an intended contour of the layer of material.
