Abstract: A converting line for coreless roll products includes a rewinding machine and a controller. A log of convolutely wound web material is wound in the rewinding machine during a wind cycle. A diameter of the log, a caliper of the web material, and an amount of tension of the web is determined at a plurality of time points during a time period of the winding cycle. The controller is enabled to generate a signal to change an operating condition of the converting line based upon at least one of a diameter determination at a time point during the wind cycle, a caliper determination at a time point during the wind cycle, a wound web amount determination at a time point during the wind cycle, and a tension determination at a time point during the wind cycle.

Abstract: A core end engagement assembly is proivded for a rewinding machine. The core end engagement assembly is configured to engage an end of the core and transmit rotational movement to the core during winding of the web material about the core. The assembly may include a drive housing. A chuck may project from a first end of the drive housing and may be configured to engage the end of the core. A first actuator may reciprocate the drive housing along a central axis of the core between an engagement and disengagement position of the chuck relative to the core. A second actuator may be mounted on the drive housing. The second actuator may be configured and adapted to move the chuck between release and hold positions. A flexible drive shaft operatively connects with and rotationally drives the chuck.

Abstract: A rewinding machine winds a web material into a log about a core. The web material to be wound is directed about a rotating winding drum. A continuous loop is spaced from the winding drum and with the winding drum defines a nip through which the core is inserted and through which the web material is directed. A surface of the continuous loop opposite the winding drum across the nip is configured to move in a direction generally opposite of the winding drum for winding the web material about the core. A rider roll defines a winding space with the winding drum and the continuous loop. The rider roll is movable relative to the continuous loop and the winding drum to allow for an increase in a diameter of the log in the winding space during winding of the web material about the core.

Abstract: A core end engagement method for a rewinding machine is proivded. For this, a core chuck is provided, the core chuck being rotatable with the core at least some time during the winding of the web material about the core, the core chuck having an end, the end comprising at least one elastomer ring adapted and configured for engaging an inside surface of the core. The end of the core chuck with the at least one elastomer ring is inserted into an end of the core while the core is rotating. The at least one elastomer ring is axially compressed to radially expand the at least one elastomer ring in a manner such that the at least one elastomer ring engages the inside surface of the core . The web material is wound about the core. The at least one elastomer ring is axially elongated to radially contract the at least one elastomer ring in a manner such that the at least one elastomer ring disengages from the inside surface of the core. The end of the core chuck is withdrawn with the at least one elastomer ring from the core end while the core is rotating.
