Abstract
A shaped conductive pattern is located very-close to the top and bottom edges of a print ribbon, e.g., 0.18″ or less, where the conductive pattern is sewn using a partially conductive thread, such as 20% steel and 80% polyester. A two-piece clamp used to sew the conductive feature has shaped opening in both pieces, a peripheral groove surrounding the shaped opening and vertical grooves outside peripheral groove in one piece, and a peripheral tongue surrounding the shaped opening and vertical tongues outside the peripheral tongue in the other piece, where the width of the vertical grooves is larger than the width of the peripheral groove.
