Abstract: A semi-automatic binder is disclosed which incorporates a conveyor for transporting a preformed length of double wire binder to a loading station. The loading station incorporates a unique support arrangement whereby the free ends of the double wire binder are presented for quick and easy manual assembly thereto of sheets to be bound. The thus assembled sheets and binder are then moved to a closing station employing an adjustable pressure bar operative to close the double wire binder. Both the support arrangement and pressure bar are readily adjustable to enable the binder of the present invention to accommodate a wide variety of sizes of double wire binders.
