Methods and apparatus for fibre preparation |
(57) The application of lubricants and other substances in fibre preparation machinery
is regulated by measuring fibre mass flow rate through the machinery at a measuring
position (14,51,45), applying lubricant to the fibre at a position (16) downstream
of the measuring position, and controlling the rate of applicaion in accordance with
the measured fibre mass flow rate after a delay corresponding to the time taken by
the fibre to pass between the measuring and application positions.
