Keep Cores from Deforming

Leaf air shafts reportedly provide the ideal support for thin wall cores of 1½ in. or larger to keep cores from deforming during winding. Trapper leaf shaft models are available for coreless winding with the lead end of a web secured under a leaf's edge to begin the winding process. When winding is completed, the web is released from the shaft easily when the leaves are retracted.
