摘要

ufeffvynu00e1lez concerns the sorting coil with the yarn according to the rigidity of the roll (41) yarns deposited on dutince (42) for dyeing. coils (4) and classified into groups according to the prodyu0161nosti roll (41).the invention relates to equipment for detecting also prodyu0161nosti roll (41) yarns, which is stored in a dutince (42) fitted with a number of pru016fchozu00edch radial holes (421), and lead (43, 44) cores (42) are closed, and the internal space of bobbins (42) is connected to the source ( 1) air pressure.and in the main pipe to the interior of the bobbins (42) is included the flow meter (2) and to the outlet manifold air pressure source (1) is connected to a pressure gauge (3).
