<p>PROBLEM TO BE SOLVED: To provide a friction winding shaft in which a plurality of winding cores can be accurately and reliably held at predetermined mutual intervals so as not to cause centrifugal whirling even when each winding core is the one having relatively low mechanical strength and a narrow width such as a paper tube and a synthetic resin tube and attaching/detaching operation of the winding core can be performed relatively easily and in a short time.SOLUTION: A plurality of winding cores C are mounted on an outer periphery of a winding collar group 4 on a center drive shaft 2 via a winding core adapter 5 for each winding core. The winding adapter 5 includes: an annular body 8 that is held by a winding collar 3 and penetrates the winding core C; winding core fixing means 9 for fixing the winding cores C fitted with an outer periphery of the annular body 8 on the annular body 8; and a rolling bearing 10 concentrically mounted with the annular body 8 at one end part of the annular body 8. The annular bodies 8 of the winding adapters 5 whose winding adapter groups 6 are adjacent to each other are in contact with each other sandwiching the respective rolling bearings 10.</p> |
