Abstract
A countersunk bending disc is mounted on a bending shaft in the machine table. On the shaft is mounted a bending roller (8), and a retention bar (7) holds a bending bolt, or the roller. In the region of the retention bar, the bending bolt, or roller is fitted a hand protection flap (12) in a preset rated position. The flap is swivelable about a horizontal axis (13) in pull-in direction. To the flap is associated a stop switch for the drive, actuated from the flap, when a hand moved in the pull-in direction has moved the flap from its rated position. USE/ADVANTAGE - Concrete reinforcing rod bending machine gives increased operator protection, reducing the injury risk.
