  • Patent number: 4244767
    Abstract: A machine which is operative for handling a roll of wound sheet-like material having a loose tail end includes rollers which rotate the roll in the rewinding direction, blowers which unwind the loose tail end off the roll during rotation, and a delivery table upon which the unwound loose tail end settles for the application of glue. A first sensor detects the unwinding of the tail end off the roll and activates a normally deactivated second sensor which turns off the rollers when the tail end reaches a predetermined location on the delivery table. Adhesive is next applied to the stationary tail end by a glue gun which is movably mounted on a pneumatically controlled carriage assembly. The glued tail end is thereafter rewound upon the roll, and the roll is subsequently ejected from the machine. A third sensor detects the initial presence of the roll upon the rollers and will initiate ejection of the roll after a predetermined time period elapses, regardless of operation of the glue gun.
