These new type Roving Frames have been developed on the basis of
experience. They are equipped with advanced computer control
technology and inverter
speed-regulation technology. With the features of high-level
electromechanical integration, simple operation, high production
efficiency and convenient maintenance, the machines are suitable for
carded and combed cotton sliver or blending, and are the best choice
making outstanding quality yarns.
HY491A is driven separately by three
motors: a main motor to drive flyer and roller operations, another for
bobbin winding, and a third for lifting and lowering the bobbin rail.
kinds of change gears for drafting and twisting are available.
Production parameters can be input conveniently by LCD touch-screen
function panel. It is simple to input, monitor and operate, and is also
very convenient to control and adjust roving tension.
HY492A is driven separately by
four motors: two of them are used to drive flyer and roller operations
separately, another one for bobbin winding, and the fourth for lifting
and lowering the bobbin rail. On the basis of HY491A, the twist change
gears are removed and the twist value can be input directly on
the operation screen. Production parameters can be input
conveniently by a color touch-screen, which is used as man-machine
interface. It is very convenient to control and adjust the roving
The production data of various specifications can be saved on the
computer, so it is not necessary to experiment and adjust when changing
the product. It is very simple and convenient to operate for its
real-time display of running state and faults warning.
