ABSTRACT:
The present invention is directed to a method and apparatus for in-line separation of polymer film and non-woven to compensate for the increased width due to stretching in the cross-machine (CD) direction. Due to the stretching in the cross-machine direction, typically by interdigital rolling or tentering, the width of individual webs is increased. To compensate for the increase in width, the apparatus and method of the present invention is employed to provide for in-line separation of the narrow webs. The apparatus of the present invention may allow for simplicity in threading the device, due to the ability to automatically thread individual turning bars by moving the turning bars across the undeflected path of the web.
