ABSTRACT:
Apparatus for cutting an annular groove about a rotating cylindrical member includes a rotating cutter positioned in cutting relation to the outer surface of the cylindrical member and including a plurality of cutting edges, each forwardly angled in relation to the direction of rotation of the cutter. The cylindrical member and cutter rotate in the same direction so that an annular groove or channel is cut in and along the outer surface of the cylindrical member. Sealing apparatus is included for providing sealing between the outer surface of such member and the inner surface of a member overlying such first-mentioned member. The sealing apparatus is of resilient material and is seated in the channel. The sealing apparatus includes a pair of elongated ribs angled in the same direction, and in contact with each other when in such sealing situation, with the elongated side surface of one of such ribs in sealing contact with the inner surface of such overlying member.
