BOBBIN CHANGER FOR FINE SPINNING FRAME

摘要

PURPOSE:To charge compressed air into bobbin-holding tools of a number necessary for doffing, by grouping plural bobbin-holding tools consisting of elastic bag counting from a compressed air source and placing a shielding means to shield a flow channel of compressed air at a proper position of a doffing bar and a position corresponding to the boundary of the groups of the bobbin-holding tools. CONSTITUTION:When a package is formed on an empty bobbin attached to a row of spindle 1 and a package is completely spun out, compressed air is charged into a bobbin-holding tool 5 of doffing bar 4. The bobbin-holding tool consists of an elastic bag. The flow of the compressed air supplied from a compressed air source 6 is stopped at a change-over valve 8 by operating the valve. Compressed air is charged only to a bobbin-holding tool 5 corresponding to the really spun-out spindle.
