BIAXIAL FABRIC BRAIDING MACHINE WITH VARIABLE NUMBER OF COILS Russian patent published in 2025 - IPC D04C3/36 

FIELD: braiding or lacing machines.

SUBSTANCE: invention is a braiding machine with a variable number of coils for producing biaxial fabric used in aircraft rocket production, which includes: a base, coils with threads, a coil base with a thread tensioning system, guide plates, coil changing mechanisms, belts, belt tensioning systems, drives transmitting rotation via belt drives to pulleys, wherein base has flat surface, on which are fixed on pulleys pairs of cam mechanisms and rotary mechanisms connected into closed polygon, at that, each cam mechanism is made in the form of two flat links pivotally connected on two side swinging sliders, on which the guide plates are fixed, and one middle swinging slider, wherein every rotary mechanism is composed of two flat links articulated at two side cams and one middle swinging slider with the ability to change the opening angles of flat links in rotary mechanisms and change the opening angles of flat links in cam mechanisms.

EFFECT: possibility of changing number of coils in braiding machine while maintaining speed of machine braiding.
