1. one kind is used for making the pultrusion method of the preform of the abnormal shape with the cross section part of extending on the angle of being in ground with quasi-continuous technology by a plurality of semi-finished product (1,2,3), has following steps:



  • dispenser device (11) is carried the semi-finished product structures (HA) of at least one multilayer, and this semi-finished product structure is imported building mortion (12);



    the semi-finished product structure is by building mortion (12), and in described building mortion, at least one cross section of semi-finished product structure partly is bent, and makes the cross section of semi-finished product structure partly form the dihedral profile;



    in pressurizing unit (13), move to together by tool piece movably, push the shape of cross section of described semi-finished product structures (HA3), this semi-finished product structure leaves described anamorphic attachment for cinemascope (12) with described shape of cross section, and and then described tool piece is separated from each other, wherein under the separated state of described tool piece, carry out the feed motion of described semi-finished product structure, and wherein in described pressurizing unit (13), carry out the heating of described semi-finished product structure, make by heating and pressure-loaded simultaneously, the curing of resin material realizes the fixing of mutual maintenance shape and the compressing of cross section part of the described cross section part of described semi-finished product structure, wherein during pushing, stop the feed motion of described semi-finished product structure;



    from described semi-finished product structures (H4), excise its longitudinal component, and take out this longitudinal component as preform with fixing layer,It is characterized in that, and semi-finished product structures (HA) described multilayer that be supplied in described building mortion (12) that carry by described dispenser device (11) are by fortifying fibre semi-finished product layer (1,3) assembly that a plurality of breadths and at least one resin molding (2) are formed, wherein said fortifying fibre semi-finished product layer (1,3) has resin glue, the ratio of described resin glue is to the maximum in 15% of the gross weight of described semi-finished product structures (HA), and as being used for fixing described fortifying fibre semi-finished product layer (1,3) binder material, and wherein at least one resin molding (2) is positioned at two fortifying fibre semi-finished product layers (1 at least,

         3) between.
