Abstract
An expandable core for handling and holding rolls of tubing. The core is comprised of support members connected to each other or a base extending along the longitudinal axis of the core by connecting links. The connecting links are pivotally attached at their terminal ends to the support members or the base rod to allow movement about a pivot assembly. Camming surfaces are mounted at the terminal ends of the support members and means for selectively expanding the core are adapted to engage the camming surface.
