Abstract
A rotating trimmer in a wire trimming machine is shown comprising a cylindrical trunk with a champhered bore for receiving an insulated wire or coaxial cable, and an open midsection for evacuating the trimmed insulation from the wire. The edge of a cutting tool is located in a slot adjacent the midsection to engage and trim the wire. The mass of the trimmer is symmetrically distributed about the longitudinal axis for uniform rotation and trimming.
Claims4
In a wire trimming machine having a motor and a rotatable shaft rotated by said motor, a trimmer comprising:
- a cylindrical trunk with a first cylindrical bore in one end thereof coaxial with the longitudinal axis thereof, a second cylindrical bore in the other end thereof coaxial with said longitudinal axis and just large enough to receive said shaft, a transverse third cylindrical bore on one side of said trunk ending at said longitudinal axis, and a transverse fourth cylindrical bore on the opposite side of said trunk prallel to and eccentric of said third bore and ending at said longitudinal axis, said longitudinal axis being coplanar with the longitudinal axes of said transverse bores;
- a pair of arcuate flange portions disposed centrally and circumferentially about said trunk and opposite each other, the ends of said flange portions terminating in parallel planes which are tangent to and which define opposite parallel sides of said trunk;
- a slot in said one side of said trunk extending through both said arcuate flanges and from the circumference to the center of said trunk, said slot forming an acute angle with said longitudinal axis of said trunk;
- and
- a cutting member disposed in one end of said slot and having a beveled cutting edge located at the inner termination of said first bore.
