Abstract

A device for chucking tubular winding cores, and particularly cores carrying paper webs or webs of similar material, wherein chucking segments forming a cylindrical surfaces are radially positioned by means of a core trunnion having an equilateral polygonal cross section, each of the chucking segments bearing on an individual surface of the trunnion through a support member having a rounded profile and producing a line contact. The support members are carried without play or with very little play in a cage inserted coaxially to be freely rotatable between the chucking segments and the core trunnion.
