METHOD AND DEVICE FOR MAKING COMPOSITE PRODUCTS CONTAINING FLAT PART Russian patent published in 2016 - IPC B29C53/82 

FIELD: machine building.

SUBSTANCE: invention relates to method and a device for making composite products, in particular profiles, containing a flat part, in a continuous process. Method of making a composite profile, having non-circular cross section, which comprises bringing into action a sequence of sections of a mandrel, having a non-circular cross section for movement in axial one-sided direction through a circular winding station which is located with possibility of rotation around longitudinal axis of mandrel, at least in one pass. Method includes continuously spirally winding using winding station a thermoplastic unidirectional tape containing beam parallel passing in longitudinal direction of fibres in thermoplastic matrix material, on sections of mandrel or pre-wound layer for forming wall layers of thin-wall profile with closed cross-section and at least one flat surface. Thin-wall profile is cut into sections placed on at least one section of mandrel. Thermoplastic unidirectional tape is heated and is pressed into sections of mandrel or previous layer, when said tape is laid so that layer is connected to previous layer before cutting.

EFFECT: high efficiency of production of profile.
