Abstract
A method of cutting a continuous hollow tubular member having a fully expanded configuration with an outer diameter D, includes the steps of feeding the continuous hollow tubular member in the fully expanded configuration to a cutting station, cutting the continuous hollow tubular member into a plurality of hollow tubular members, each of which has a first flattened end and expanding the first flattened end of the plurality of hollow tubular members to the fully expanded configuration such that the first end of the plurality of hollow tubular members has an outer diameter D.
Claims11
A method of cutting a tubular member, including the steps of:
- introducing a tubular member into an apparatus having a cutting station, the cutting station having a first wheel having at least one cutting member located on the circumference of the first wheel, the cutting member having a cutting portion and a second wheel having at least one projection located on the circumference of the second wheel;
- guiding the tubular member between the first and second wheels;
- rotating the first and second wheels such that the cutting portion is positioned opposite the projection and has a tangential speed substantially equal to the linear speed of the tubular member while cutting the member.
A method of cutting a continuous hollow tubular member having a fully expanded configuration with an outer diameter D, including the steps of:
- feeding the continuous hollow tubular member in the fully expanded configuration to a cutting station;
- cutting the continuous hollow tubular member into a plurality of hollow tubular members, each of which has a first flattened end;
- and
- expanding the first flattened end of the plurality of hollow tubular members to the fully expanded configuration such that the first end of the plurality of hollow tubular members has an outer diameter D.
