Abstract:
A seal for toner cartridge used in electrophotographic devices comprising: an elongated strip of fibrous non-woven material having a principal longitudinal axis and having axially aligned fibers lightly fused together in a synthetic resinous film to have substantial tensile strength in an axial direction and relatively less strength in a direction normal to said principal axis; said strip including a leading end and a trailing end and being bounded by first and second longitudinal edges, and first and second surfaces; adhesive means on said second surface adapted to adhere to a toner cartridge to overlie a toner dispensing slot therein; said strip having transversely extending areas of relatively greater degree of fusion to increase a transverse burst strength thereof without affecting the ability to be torn in an axial direction from said leading end to said trailing end between said longitudinal edges.
