ABSTRACT:
A machine for cutting and crimping the ends of a helical coil inserted into holes at an edge of a book to hold the coil in place is adjustable to accommodate different diameters of coil. A guide member for centering the axis of the coil in a centering direction is adjustable to accommodate different diameter coils and for adjusting the location of the axis in an adjustment direction at right angles to the centering direction depending upon the diameter of the coil. A cutting device has a blade movable in a slot of an anvil to shear on one side and to bend on the other side to form a crimped end portion. The adjustment of the axis causes the cutting device to cut the end portion longer for larger coils. The cutting device is adjustable to rotate the anvil relative to the axis to accommodate different helix angles.
