  • Patent number: 8601923
    Abstract: A rod cutter having two cutters that are exchangeable and with one thereof being operatively stationary and the other being pivotally and with cutting edges therebetween. A cover extends over the cutters so that access to the cutters is available, and they can be interchanged in their installed positions to reposition the cutting edges exposed to the rod. A ball bearing supports the pivotal cutter and it has an axial restriction for rendering axial support to the pivotal cutter. The method of cutting with both radial and axial cutter support is described.

    Abstract: A cutting mechanism and method for a tooling head is provided, the tooling head including a housing; a cord line feeding passageway extending through the housing to an applicator end, and an applicator assembly at the applicator end for application of the cord line to an annular surface. The cutting mechanism provides a reciprocally moving plunger body housed within the tooling head; a reciprocating cutting member moving between a first position cutting the cord line and a second position in a non-cutting relationship with the cord line; a cutting member being coupled to the plunger body to translate reciprocal movement of the plunger body to reciprocal movement of the cutting member between the first and second positions. A stream of air may be directed into the cord line passageway proximate the cutting member to assist in threading a severed free end of the cord through the passageway to the applicator assembly.
