Abstract
A cutting interment (10) for use on multi-strand plastic fiber materials. Opposed handles (22a and 22b) on arms (18a and 18b) may be manually operated to close jaws (14a and 14b) with a cavity (42) for crimping. At the base of the cavity (42) are cutting edges (52a), which employ heat from either heating elements (54a and 54b) or an external source to cut and simultaneously cauterize the cut ends. Optional reliefs (44 and 46) may also be provided to contain and focus the heat at the cavity (42) and thus efficiently apply it specifically to the working material.
Claims12
An instrument for cutting multi-strand plastic material, comprising:
- a first jaw part attached to a first arm member;
- a second jaw part attached to a second arm member;
- pivot means for attaching said first and second arm members in pivotally movable manner such that said jaw members can be manually positioned together and also positioned apart;
- crimping means for compressably holding the multi-strand plastic material, wherein said crimping means is located in said first and second jaw parts;
- said crimping means including at least one cavity formed between a first wall surface located in a first mating surface in said first jaw part and a second wall surface located in a second mating surface in said second jaw part, to facilitate controllably directing into place and capturing the multi-strand plastic material;
- cutting means for cutting the multi-strand plastic material;
- heat applying means for molding the multi-strand plastic material within said cavity of said crimping means and cauterizing the multi-strand plastic material during operation of said cutting means;
- heat concentrating means for directing the heat from said heat applying means into said crimping means;
- and
- said heat concentrating means including at least one relief formed by a first recess located in said first mating surface and a second recess located in said second mating surface, to retard the flow of heat away from said crimping means elsewhere into said first and second jaw parts.
