METHOD FOR CONTROLLING DEFORMATION OF FIBROUS MATERIAL DURING ITS WINDING AND FORMING ELEMENT FOR THIS METHOD Russian patent published in 2023 - IPC B29C70/06 

FIELD: machine engineering.

SUBSTANCE: group of inventions relates to a method for controlling the deformation of a fibrous material during its winding and to a shaping element for this method. The control method includes step S1: lifting a plurality of positioning pins located on the surface of the forming element, in accordance with the projected position of the fibrous material, which is wound on the forming element. Step S2: winding the fibrous material onto the forming element and ensuring that the plurality of crossing points of the main marking thread and the weft marking thread located on the fibrous material respectively overlap the positioning pins. Step S3: retraction of the raised positioning pins. Step S4: enveloping the fibrous material with the fixing mould and injecting the resin after vacuuming. In accordance with the present disclosure of the invention, a method for controlling the deformation of a fibrous material during its winding and a shaping element for this method are provided.

EFFECT: group of inventions provides the possibility of deformation of the fibres in the fibrous material during the winding process in accordance with the design requirements.
