An improvement in coil binding machines of the type having front and rear clamps for the book spine during insertion of the spiral wire. The improved machine permits the book to be placed in position for clamping with the operator either sitting or standing, and with the book being inserted vertically, horizontally, or at any intermediate angular position. The invention comprises a pair of arcuate plates on opposite sides of the machine which support the coil binding mechanism therebetween and are rotatably adjustable so that the facing surfaces of the two clamps are either vertical, horizontal or angularly disposed. A table is secured adjacent the rear clamp so that the book may be placed thereon. The side plates are provided with locking means for their adjusted position.
