Abstract
The invention provides an apparatus and method of inserting a lightweight, oversized, inside head to the end of a partially wrapped roll. An inside head is attached to multiple articulated arms extending from a spider assembly. The spider is moved toward the end of the roll until the articulated arms engage the end of the roll. The spider assembly opens the articulated arms radially outwardly until adjacent a wrapper tube extension. A heating clamp then welds the outer edge of the inside head to the wrapper tube extension.
