ABSTRACT:
A retractable and extendable support journal for engaging and supporting paper web winding tubes in a printing press utilizes a plurality of spaced radially extendable and retractable clamping strips to securely connect the winding tube to the support journals. Each clamping strip has one or more material compressing or compacting ribs which compact the material of the winding tube to insure an interlocking connection between the tube and the support journal.
