Abstract
A core holder for a winding apparatus for winding webs of material in the paper, printing, and textile industries, including a rotatable core-receiving spindle or mandrel, and a segmented friction core holder, expandable outwardly at selected points, by which the core is tightly gripped when the mandrel is turning, and which readily releases its grip on the mandrel upon a simple manual maneuver by the operator, and is readily removable with little force. The core holder assembly is round, but the mandrel-receiving hole has segmented arcs which are not concentric with the outer surface of the core holder, creating stops which limit the movement of the segments about the mandrel.
