Abstract:
A compact and portable coil inserting machine for binding stacks of sheets having a plurality of perforations along a first side edge, said machine comprising:a frame including a support surface configured to support a stack of sheets thereon, said support surface defining a first side portion;a powered roller rotatably mounted to said frame and extending along at least a portion of said first side portion and driving a helical coil through the perforations in the stacked sheets on the support surface; andat least one guide movably mounted to said frame and shifting between at least first and second positions, said guide positioned in a spaced-apart relationship relative to said roller, said guide including a first concave guide surface defining a first curvature corresponding to the curvature of a first size of helical coil, said first guide surface abutting an opposite side edge of the stacked sheets when said guide is in said first position, such that the perforations in the stacked sheets form a curved passageway corresponding to the curvature of a first coil size and facilitate insertion of the first-sized coil in the perforations, said guide including a second concave guide surface defining a second curvature corresponding to the curvature of a second size of helical coil, different than the first coil size, said second guide surface abutting an opposite side edge of the stacked sheets when said guide is in said second position, such that the perforations in the stacked sheets form a curved passageway corresponding to the curvature of a second coil size and facilitate insertion of the second-sized coil in the perforations, such that said guide can be quickly and easily reconfigured to accommodate helical coils of different sizes and facilitate insertion of the various coils through the perforations of the stacked sheets.
