Wear Plates for Stitcher Bonnet
In a wire stitcher increased life is attained by providing wear surfaces for the
sliding members of the stitcher.
In the figure stitcher 10 consists of metal bonnet 11 with the customary driver
slide 12, bender bar slide 13, and staple driver 14. In the manufacture of the
stitcher, wear plate 15 is inserted between bonnet 11 and sliding members 12
and 13. Wear plate 15 is a member which provides lubricating action, such as
TeflonR (E. I. du Pont de Nemours & Co., plastics with additives, such as
molybdenun disulfide, or oil-filled sintered metals. In this manner, the steel-to-
steel friction of the sliding parts of an ordinary stitcher is avoided.
Since the wear plates are molded, additional features can be easily
incorporated into the wear plates such as integral cam 16. Since the stitcher with
the wear plates has less shear in use, less expensive bonnets can be made from
materials such as aluminum alloys.
