FIELD: technological processes.
SUBSTANCE: impregnation and wipe-off unit is made as a single chamber. The chamber has the inner surface in the form of a right circular truncated cone with the conicity of 0.01-0.10. At the cone base, the plate with openings for the roving entry is located. The opening for the impregnated roving exit has the diameter exceeding the specified diameter of the desired product in 0.45-0.50%. Two coaxial openings for feeding a binder into the chamber are located on the axis perpendicular to the cone axis. A refrigerator is additionally installed between the impregnating and wipe-off unit and the profiling die.
EFFECT: increasing the strength of the desired product.
