Abstract
A cutting assembly for plastic film or other sheet wrapping material dispensers. The cutting assembly comprises a member having a length corresponding to the length of the dispenser box, and a U-shaped cross-section adapted to slip over the free edge of the front panel of the dispenser box. The member has a base web with one leg on the inside of the box and a second leg exposed on the outside of the box. The legs meet the web in curved shoulders, diverge downwardly and outwardly, and have extending flaps at their lower ends which are curved back internally of the U-shaped member to provide retainer edges which project angularly upward and inward of the U-shaped member to resist upward displacement of the member from the panel. The proportions of the inwardly curved flaps and the distance between them are such that there is no possibility of the leg or legs of one cutting blade interlocking with the leg or legs of another cutting blade. The open distance between the inwardly curved flaps is somewhat less than the thickness of the panel, and is substantially less than the width of the web, so that the web of one member cannot become interlocked between the legs of other members. The base web of the blade has a flat medial portion, extending between the legs and supporting the teeth.
