Suction jet, for an open-end spinner or bobbin winder, has an increasing clear cross section from the inflow to the outflow openings to take longer yarn loops without knotting or tangling

摘要

The suction jet for an open-end spinner or bobbin winder, to maintain yarn tension or take up surplus lengths during a yarn break or bobbin change, has a jet body (12) with a clear cross section of the suction jet (5) increasing continuously from the inflow opening (7) at one end axially to the outflow opening (10) at the other end.
