Abstract

A machine and method for winding coreless rolls from an indefinite length web by winding a spiral body in a winding pocket with a trailing end extending upstream from the pocket, releasing the body from the pocket and accelerating the body and trailing end downstream away from the pocket while winding the trailing end onto the body to complete the roll and to create a gap between the trailing end and the leading end of a web fed toward the pocket. Fingers are extended through the gap to guide the leading end of the web and into the pocket and intricate winding of the next roll.
