Tape-severing device

An improved tape-severing device of the type operatively mounted for sliding movement about a core supporting a supply length of tape put up in a roll, said tape-severing device comprising an arcuate shaped slide member operatively arranged to partake of said sliding movement along said core and having mounting openings in opposite sides thereof, a tape-severing body member presenting a tape-severing edge thereon and having bifurcated opposite legs extending in depending relation therefrom terminating in mounting projections facing each other, said tape-severing body member having an operative position disposed in straddling relation over said roll of tape with each said mounting projection thereof projected within and cooperating with one of said mounting openings so as to allow for rotative movement therebetween contributing to corresponding pivotal movement in said tape-severing body member relative to said roll of tape, and movement-binding means consisting of circumferentially spaced radially extending teeth on each said mounting projection and a surface bounding each said cooperating mounting opening of a selected construction material that binds upon physical contact with said teeth so as to allow pivotal movement in said tape-severing body member in only one selected direction, whereby as said supply of tape is payed out from said roll progressively diminishing the height thereof said tape-severing body member is nevertheless adapted to assume an operative position adjacent said roll of tape due to a pivotal movement therein and is effectively held in said operative position by said movement-binding means.
