    摘要: The invention relates to an inline method for producing a spring strip profile (1) for a slatted frame, which spring strip profile (1) comprises at least one core strand (2) formed by a fibre-reinforced plastic and at least one thermoplastic cover layer (3) surrounding the core strand (2), wherein the method comprises at least the following steps: joining multiple fibres, threads and/or filaments to form a fibre bundle (2.1); impregnating the fibre bundle (2.1) with a thermally activatable reaction resin; moulding the outer contour of the fibre bundle (2.1) impregnated with the reaction resin; thermally activating the reaction resin (2.1) to form a cured core strand; introducing the core strand (2) into an extruder head (110); applying thermoplastic melt in the extruder head (110) to form the cover layer (3) on the spring strip profile (1); cooling and calibrating the spring strip profile (1) in a cooling and calibrating device (111, 112, 113), wherein, in a winding machine (105), the outer contour of the fibre bundle (2.1) is wrapped around by at least one thread or filament (2.2) supplied laterally in relation to the fibre bundle in at least one position and orientation, and wherein, in a heating section (106), before the core strand (2) is introduced into the extruder head (110), at least a partial curing of the reaction resin is achieved at least in the wrapped outer layer of the fibre bundle (2.1).
