Method of cutting tubular members and apparatus therefor
View Patent ↗A method of cutting a polymeric tubular member and apparatus therefor is provided. The method includes moving the polymeric tubular member along a central longitudinal axis into a position to be cut. Further, providing at least one actuator with a cutting blade operably connected to the at least one actuator, with the cutting blade extending lengthwise along a cutting blade axis. Then, actuating the at least one actuator and moving the cutting blade into cutting engagement with the polymeric tubular member along a driven axis that extends in oblique relation to the cutting blade axis.
1. A method of cutting a polymeric tubular member, comprising:
moving the polymeric tubular member along a central longitudinal axis into a position to be cut;
providing at least one actuator;
providing a cutting blade operably connected to said at least one actuator, said cutting blade having a leading cutting edge that extends lengthwise along a cutting blade axis; and
actuating said at least one actuator and moving the leading cutting edge of said cutting blade into cutting engagement with the polymeric tubular member and driving said cutting blade along a substantially straight driven axis that extends in oblique relation to the cutting blade axis without tilting said cutting blade axis of said leading cutting edge during movement of said cutting blade along said driven axis through the polymeric tubular member.
2. The method of claim 1 further including orienting the driven axis in perpendicular relation to the central longitudinal axis.
3. The method of claim 1 further including bringing a cutting region of the cutting blade into cutting engagement with the polymeric tubular member, the cutting region extending over a length of the cutting blade that is greater than a diameter of the polymeric tubular member.
4. The method of claim 1 further including providing said at least one actuator as a plurality of actuators.
5. The method of claim 4 further including providing said plurality of actuators as a pair of actuators.
6. The method of claim 4 further including configuring the plurality of actuators in operable communication with one another.
7. A method of cutting a polymeric tubular member, comprising:
moving the polymeric tubular member along a central longitudinal axis into a position to be cut;
providing a plurality of actuators in operable communication with one another;
providing a cutting blade operably connected to said plurality of actuators, said cutting blade extending lengthwise along a cutting blade axis;
actuating said plurality of actuators and moving the cutting blade into cutting engagement with the polymeric tubular member along a driven axis that extends in oblique relation to the cutting blade axis; and
further including driving a first one of the plurality of actuators at a linear speed relative to the linear speed of a second one of the plurality of actuators.
8. A method of cutting a polymeric tubular member, comprising:
moving the polymeric tubular member along a central longitudinal axis into a position to be cut;
providing a plurality of actuators;
providing a cutting blade operably connected to said plurality of actuators, said cutting blade extending lengthwise along a cutting blade axis;
actuating said plurality of actuators and moving the cutting blade into cutting engagement with the polymeric tubular member along a driven axis that extends in oblique relation to the cutting blade axis; and
further including configuring a first one of the plurality of actuators to drive along a first direction and a second one of the plurality of actuators to drive along a second direction substantially perpendicular to the first direction.
9. The method of claim 1 further including heating the cutting blade prior to cutting the polymeric tubular member and substantially maintaining the temperature of the heated cutting blade while cutting the polymeric tubular member.
10. The method of claim 1 further including providing the polymeric tubular member as a textile sleeve.
11. The method of claim 10 further including providing the textile sleeve having a circumferentially discontinuous wall with an open seam extending substantially parallel to the central longitudinal axis.
