  • Pressure actuated clamp for truss manufacturing equipment
    Patent number: 4660815
    Abstract: A clamping apparatus is disclosed for use in clamping wooden chord and web members together in manufacturing wooden trusses. The clamping apparatus uses an inflatable conduit (50) to force an elongated clamp to a closed position. In a second embodiment, two inflatable conduits (150 and 152) move a tubular member (136) in opposite directions for urging a truss (120) against a stationary brace (32). Tubes (150 and 152) are selectively inflated and deflated through a valve (170).
