Abstract
A suction arrangement for a device for repositioning the reserve winding typically found on cops from a ring spinning machine to prepare the cops for rewinding into larger yarn packages at a bobbin-winding machine. The suction device is connected to a central supply of suction air to aspirate and hold the yarn end until it is re-deposited on the cop, and includes an air flow restrictor plate movable among multiple positions for selectively obstructing the suction air flow to apply respectively different suction forces to the yarn end based on predetermined parameters of the yarn, the cop preparation operation, or the particular winding operation.
