ABSTRACT:
A combination work station for open wire element bindery operations is provided with a base plate having a planar work surface with a die punch for perforating pages resting upon a first work station on the work surface, and the bindery press for pressing closed open wire binding elements at a second work station on the common work surface. The bindery press is manually operated and is provided with a moving platen sliding upon inserted guide posts extending normally up from the work surface. Adjustment means incorporating adjustment screws interfitting through threaded traveler blocks attached to the platen are provided. Compressive coil springs circumvolving the adjustment screws provide compressive force for returning the press from its closed to open position.
