A winding tube has a tubular body and a removable and replaceable end ring. The end ring has opposite end faces that, according to one embodiment, each define at least two recesses that form start-up regions between the end ring and the tubular body for capturing yarn during a winding operation. The recesses are spaced apart from one another so as to allow the end ring to be easily mounted and secured to the tubular body, and allowing the end ring to be reversible in relation to the tubular body.
