Abstract
A manual tool for rolling and positioning a mass of material. More particular, for use with rolls of stratified materials having a central core. The tool when inserted into the central core of such stratified rolls articulates in a manner so as to allow a cleat member to grip the outer perimeter of the roll and thereby allows the workman to apply leverage to the mass causing rotation. Repeated articulated movements allows the tool to be operated in a ratcheting manner.
