Abstract
A coreless surface winder and method wherein two of the winding drums are slightly spaced apart by a distance less than two web thicknesses which then operate to cause a folded leading edge on a transversely severed web to roll upon itself and develop an incipient log which thereafter is completed in a conventional three drum cradle to provide a coreless retail sized roll.
