Two employees were performing a coil change operation in the front end of a lubricator. The aluminum coil bunched up while the two employees were performing the coil change and jammed the machine as it was being fed through the rollers. The employees then had to reverse the machine to get the aluminum coil out of the machine. One employee was operating the controls while the injured employee was helping feed the aluminum coil. As the machine was put into reverse, the injured employee had his hands on the aluminum coil and his right hand was sucked into the machine, resulting in amputation of his index finger, a crush injury to the right thumb and the loss of flesh from the palm and fingers.
