Abstract
A combination inserter and binder machine for wire loop element is easily adjustable for a wide range of diameters of element, preferably without the use of tools or changing of the tool surfaces that perform the closing. The user inserts a stack of punched paper onto a table so that the paper edge slides into the open wire element that is held in place between an upper and lower tool. The upper tool is actuated to move down relative to the lower tool to close the wire element. The surfaces of the upper and lower tools that are presented to the element are preferably V-shaped at an angle or range of angles that are found to be effective for handling the wide variety of diameters. The adjustments made prior to changing to a different diameter of wire ensure that all the paper will slide into the elements smoothly without hanging up or sliding above or below the element. The adjustments also ensure that, when the element is closed, the narrow loops will close to the proper extent and through the holes of the paper.
