An employee was performing a roll transfer on a turret winder. After indexing the turret, she was about to separate the bag at the perforation but noticed that the bag had not adhered to the new core. She tried to reach over the finished roll (which was on the rear spindle) to tuck the bag onto the new core (which was on the front spindle). Her hand was pulled into the front spindle, and her right forearm was broken. She was hospitalized.
