Abstract: A device and a method wind a thread on a winding machine. The winding machine has a spool sleeve and a spool holder, which has two oppositely disposed centering plates, having an adjustable axial distance relative to each other, for tensioning the spool sleeve. The centering plates each have a centering cone which engages in an open spool sleeve end, and an arrester hook for arresting the thread being provided in one of the centering plates. The arrester hook is oriented in the circumferential direction of the centering plate, and the centering plate having the arrester hook contains an outer cone which overlaps the outer diameter of the spool sleeve end. An inside of the arrester hook is formed by a nose-like recess provided in the outer cone.
