An employee was running acrylic film through an automated winding machine which wraps film around a cardboard cylinder core. He noticed that the film had slipped off the winder. He went to the front of the machine to re-attach the film to the winder spool. His fingers got caught between the film and the spool and his left arm was pulled up by the winder spool. The employee was hospitalized with a broken left forearm. Another employee injured their shoulder when pulling the first injured employee out of the machine.
