Abstract: A rotor winder and a method for operating the rotor winder, wherein the rotor winder has two rotors supported in a rotatable rotor with two winders which are driven independently from one another and are provided for successive continuous winding of hot strip. Each winder has a winder mandrel including several moveable segments for expanding the winder mandrel, wherein the segments are supported on axially moveable wedge-shaped gliding surfaces. The winders are moveable in cycles from an initial position into the coil transfer position by rotation of the rotor. A device is provided for guiding an incoming hot strip onto the winder mandrel of the winder positioned in the initial position and for holding the strip on the winder mandrel until a slip-free engagement of the strip is effected. The device for guiding and placing the incoming strip is arranged on a power-driven frame mounted so as to be moveable in a direction extending parallel to the axis of the winder.

Abstract: The invention relates to a strip winder (1) for winding a hot or cold strip (25) into a coil, comprising a winder mandrel (2), pressure rolls (6-8) which can be in the form of comb rolls (6′-8′) deflection cups (9-11), and a feed shaft (20). The aim of the invention is to improve a strip winder of this type so that a hot or cold strip (25) can be wound securely on the winder mandrel (2) even at high speeds and when the strip is thin. To that end, the deflection cups (9-11) have channels (18) whose outlet openings (19) are located in the cup area and the channels (18) are connected to a medium supply system.
