An employee was setting up press rolls. He was between quests and changing the width of the spider arms on the press to install a different roll on the rotating spider arms. He left one roll on top and removed the bolts that keep the spider arms in a fixed position. The weight of the roll fell down and hit him in the left shoulder as he was jumping out of the way. His foot got caught on the transfer table, and he twisted and fractured his right ankle. He also bumped his chin and received several scrapes on his right leg.
