Abstract (en)
[origin: EP0453800A2] A tensioning head for a web wound onto a tube comprises a supporting arm and a tensioning mandrel which is arranged displaceably in said arm and can be introduced into the tube. For the purpose of providing a space-saving ejection device for the tube of an unwound web, which is of simple design and does not require an independent drive, there is an ejector ring which surrounds the tensioning mandrel, is guided displaceably on the supporting arm parallel to the direction of movement of the tensioning mandrel and is supported resiliently with respect to the supporting arm. <IMAGE>
