Abstract
An improved carrier tape is provided comprising a cover strip and a base strip formed of a plastic material and designed to mechanically interlock with each other. The cover strip includes a top surface from which opposed sidewalls extend downwardly. The spacing between at least portions of the sidewalls is substantially equal to the width of the base strip so as to engage the sidewalls of the base strip in a mechanical interlock. At least one of the sidewalls includes a segment extending outwardly away from the other sidewall so as to define a camming surface to which a force may conveniently be applied to urge the sidewalls apart and thereby facilitate the application of or removal of the cover strip from the base strip. The cover strip may further be provided with a hump which, in cross section, has a dovetail configuration. A method for forming the cover strip and work piece used in practicing the method are also disclosed.
