Abstract

A cutting blade assembly for use with a rotating cable preparation device includes a cutting blade defining a cutting edge and adapted to attach to a rotating member of the cable preparation device. The cutting blade assembly is selectively movable in a cutting direction for at least partially cutting a cable held by the device. The assembly further comprises a blade stop positioned adjacent to the cutting edge of the blade and defining a stop surface. The stop surface is arranged at a predetermined distance from the cutting edge of the blade in a depth direction of the blade, and extends in a direction generally perpendicular to the cutting direction and generally parallel to an axis of the cable.

First claim

What is claimed is:

1. A cutting blade assembly for use with a cable preparation device, comprising:
a cutting blade defining a cutting edge and adapted to attach to a rotating member of the cable preparation device, the cutting blade selectively movable in a radial cutting direction with respect to a cable held by the device, the cutting blade including a body having a first end for attaching to a blade holder of the device, a second end defining the cutting edge, and an intermediate portion tapering between the first end and the second end; and
a blade stop oriented adjacent to the cutting blade, the blade stop including a body having a first end for attaching to the blade holder, a second end defining a stop surface arranged at a predetermined distance from the cutting edge of the blade in a depth direction of the blade, and an intermediate portion tapering between the first end of the blade stop and the second end of the blade stop, the blade stop is adapted to engage with an outer surface of the cable after the blade reaches a cutting depth through the cable corresponding to the predetermined distance.

2. The cutting blade assembly of claim 1 , wherein the stop surface is curved in a radial direction with respect to an axis of rotation of the rotating member.

3. The cutting blade assembly of claim 1 , wherein the cutting blade is one of a plurality of cutting blades and the blade stop is one of a plurality of blade stops, with each blade stop arranged adjacent to one of the cutting blades.

4. The cutting blade assembly of claim 3 , wherein the plurality of blade stops each have the stop surface, and the plurality of stop surfaces of the plurality of blade stops are sized and shaped so as to define a majority of a circle for simultaneously engaging with an outer circumferential surface of the cable.

5. The cutting blade assembly of claim 4 , wherein the plurality of cutting blades each have the cutting edge, and the plurality of cutting edges of the plurality of cutting blades are sized and shaped so as to define a majority of a circle for simultaneously engaging with a majority of the outer circumferential surface of the cable.

6. The cutting blade assembly of claim 3 , wherein each of the plurality of cutting blades are rotatable.

7. The cutting blade assembly of claim 1 , wherein the cutting edge of the cutting blade is defined at a vertex defined between a first vertical sidewall of the cutting blade and a second sidewall of the cutting blade.

8. The cutting blade assembly of claim 7 , wherein the stop surface of the blade stop is arranged directly adjacent to and abutting the first vertical sidewall.

9. The cutting blade assembly of claim 1 , wherein the blade stop extends from the body of the blade in a direction generally perpendicular to the radial cutting direction.

10. A cable processing machine comprising:
a rotating member rotatable about an axis; and
a plurality of blade holders rotatably attached to the rotating member, each blade holder having:
a blade defining a cutting edge; and
a blade stop arranged adjacent to the cutting edge of the blade and defining a stop surface, the stop surface offset a predetermined distance from the cutting edge of the blade in a depth direction of the blade and having a semi-circular profile corresponding to that of an outer surface of a cable, the blade stop is adapted to engage with the outer surface of the cable after the blade reaches a cutting depth through the cable corresponding to the predetermined distance.

11. The cable processing machine of claim 10 , wherein a cable processed by the machine is held generally axially aligned with the axis of the rotating member.

12. The cable processing machine of claim 11 , wherein the blade holders are adapted to simultaneously rotate relative to the rotating member for adjusting a radial position of the blades relative to the cable.

13. The cable processing machine of claim 10 , wherein each blade and blade stop are fixed with respect to a respective one of the blade holders via at least one locating pin.

14. The cable processing machine of claim 13 , wherein each blade and blade stop are secured to a respective one of the blade holders via a fastener.

15. The cable processing machine of claim 10 , wherein each blade stop is adapted to engage with a outer surface of the cable after the blade reaches the cutting depth through the cable corresponding to the predetermined distance.

16. The cable processing machine of claim 10 , wherein the plurality of stop surfaces of the plurality of blade stops are sized and shaped so as to simultaneously engage with a majority of an outer circumferential surface of the cable.

17. The cable processing machine of claim 10 , wherein the plurality of blade stops are resiliently mounted to the plurality of blade holders in a radial direction with respect to the axis of the rotating member.

18. A cutting blade assembly for use with a rotating cable preparation device, comprising:
a cutting blade adapted to attach to a rotating member of the cable preparation device, the cutting blade selectively movable in a cutting direction with respect to a cable held by the device, the cutting blade defining a cutting edge at a vertex defined between a first vertical sidewall of the cutting blade and a second sidewall of the cutting blade; and
a blade stop defining a stop surface arranged at a predetermined distance from the cutting edge of the blade in a depth direction of blade and directly adjacent to and abutting against the first vertical sidewall of the cutting blade, the blade stop is adapted to engage with an outer surface of the cable after the blade reaches a cutting depth through the cable corresponding to the predetermined distance.

19. The cutting blade assembly of claim 18 , wherein the cutting blade is one of a plurality of cutting blades and the blade stop is one of a plurality of blade stops, with each blade stop arranged directly adjacent to one of the cutting blades.

20. The cutting blade assembly of claim 19 , wherein a plurality of the cutting edges of the plurality of cutting blades are sized and shaped so as to define a majority of a circle for simultaneously engaging with a majority of the outer surface of the cable.
