ABSTRACT:
There is disclosed chuck configurations for internally engaging the hollow core element of a roll of packaging or printing sheet or other web material in which a generally cylindrical chuck body insertable in a web core has at least one hole through the chuck body at an acute angle with the tangent to the chuck body at the outer entrance point of the hole and at an acute angle with the plane perpendicular to the chuck cylindrical axis. At least one elongated element is configured to engage rotatably in each of the holes and having on a distal end thereof one or more pointed or toothed extensions for engagement with the interior of a hollow web whereby chuck engagement with a hollow core may be made by manipulating such elongated elements to extend outside the periphery of said chuck body. The chuck may also be provided with means for securing it on a spindle or shaft for rotation therewith which is separate and independent of the holes and elongated elements for engaging the hollow core.
