Winding apparatus with roll transfer means and method
First Claim
1. A winding apparatus comprising a pair of spaced apart upstanding end frames, a plurality of elongate driving rolls extending between said end frames and mounted for rotation about parallel spaced apart axes for supporting a roll of web material wound about a core at a first winding position and in engagement with one of said driving rolls during winding to a predetermined initial size and for supporting the roll of web material at a second winding position and in engagement with the other of said driving rolls during continuation of winding to a final size, means for engaging winding cores closely adjacent opposite ends thereof and for feeding engaged winding cores along a predetermined path of travel to the first winding position for winding of successive rolls of web material, means for transferring a roll of web material wound about a core from the first winding position to the second winding position including a pair of movable transfer arm means for engaging the winding core of the roll of web material at locations spaced inwardly from opposite ends thereof and on opposite sides of the roll of web material when the roll is in the first winding position and for displacing the roll to the second winding position, said pair of transfer arm means being movable along a path intersecting said path of travel of winding cores being fed to the first winding position, and control means operatively connecting said core feeding means and said pair of transfer arm means for moving the same in sequential timed relation.

Abstract
A winding apparatus and method in which a roll of web material is supported at a first winding position during winding to a predetermined initial size and at a second winding position during continuation of winding to a final size, the apparatus having mechanism for feeding winding cores along a predetermined path of travel to the first winding position and a pair of transfer arms which move along a path intersecting the path of travel of winding cores fed to the first winding position for engaging a winding core of a roll of web material in the first winding position and displacing the roll to the second winding position, with the movement of winding cores and the pair of transfer arms occuring in sequential timed relation so as to avoid interference therebetween.

- 5. A winding apparatus comprising a pair of spaced apart upstanding end frames, a plurality of elongate driving rolls extending between said end frames and mounted for rotation about parallel spaced apart axes for supporting a roll of web material wound about a core at a first winding position and in engagement with one of said driving rolls during winding to a predetermined initial size and for supporting the roll of web material at a second winding position and in engagement with the other of said driving rolls during continuation of winding to a final size, magazine means for receiving and retaining a plurality of winding cores, means for engaging winding cores closely adjacent opposite ends thereof and for sequentially feeding winding cores along a predetermined path of travel from said magazine means to first winding position for winding of successive rolls of web material, means for transferring a roll of web material wound about a core from the first winding position to the second winding position including a pair of movable transfer arm means for engaging the winding core of the roll of web material at locations spaced inwardly from opposite ends thereof and on opposite sides of the roll of web material when the roll is in the first winding position and for displacing the roll to the second winding position, said pair of transfer arm means being movable along a path intersecting said path of travel of winding cores being fed to the first winding position, and control means operatively connecting said core feeding means and said pair of transfer arm means for moving the same in sequential timed relation and thereby avoiding interference therebetween.

9. Winding apparatus comprising a pair of spaced apart upstanding end frames, means for receiving elongate winding cores which extend substantially from one of said end frames to the other and for supporting a core in a first winding position for winding a roll of web material to a predetermined initial size, the web material optionally being of full width so that only short opposite end portions of the core extend beyond the roll or of considerably lesser width so that substantial opposite end portions of the core extend beyond the roll, means for receiving the initial size roll of web material from the first winding position and for supporting the roll in a second winding position during continuation of winding to a final size, and a pair of transfer arm means adjustably movable inwardly of said end frames for being positioned closely adjacent opposite ends of the initial size roll of web material for engaging the opposite end portions of the winding core at locations spaced inwardly from opposite ends thereof and transferring the same from the first winding position to the second winding position whereby transfer of various width rolls may be smoothly effected without encountering flexure and rupture of winding cores.
