Spool having flange with locking notch
A spooler for winding a material onto a spool includes a feeding unit for feeding the material to the spool and a spool drive flange for winding the material onto the spool. The spool includes a barrel and at least one flange disposed on the barrel. The flange is provided with a locking notch having a receiving portion for receiving an outermost end of the material and a retaining portion for retaining the outermost end of the material within the locking notch. The receiving portion or the retaining portion may have a reduced cross-section area for securing the outermost end of the material. A method for retaining a length of a continuous, elongate, flexible material on a spool includes winding the material onto the spool and retaining an outermost end of the material within a locking notch provided on at least one flange of the spool.

wherein an innermost end of the material is received within a feeding hole of the barrel of the spool, and wherein an outermost end of the material is received within the locking notch of the at least one flange of the spool; and
wherein an attachment clamp of a spooler comprises a pair of pins disposed within the barrel of the spool that close together to thereby grip the innermost end of the material within an interior of the barrel of the spool.
2. The spool according to claim 1 , wherein the locking notch further comprises a transition region between the receiving portion of the locking notch and the retaining portion of the locking notch.
3. The spool according to claim 1 , wherein at least one of the receiving portion of the locking notch and the retaining portion of the locking notch has a reduced cross-section area for securing the material within the locking notch of the at least one flange of the spool.
4. The spool according to claim 1 , wherein the receiving portion of the locking notch extends in a generally circumferential direction of the at least one flange of the spool.
5. The spool according to claim 4 , wherein the retaining portion of the locking notch extends in a generally radial direction of the at least one flange of the spool.
6. The spool according to claim 1 , wherein the receiving portion of the locking notch extends in a generally radial direction of the at least one flange of the spool.
7. The spool according to claim 6 , wherein the retaining portion of the locking notch extends in a generally circumferential direction of the at least one flange of the spool.
8. The spool according to claim 1 , wherein a spool drive flange of a spooler is operable for transferring rotational movement to the spool during a spooling process.
9. A spool configured for winding a length of a continuous, elongate, flexible material onto the spool, comprising:
an elongate barrel defining a longitudinal axis in an axial direction and having a length in the axial direction; and
at least one flange disposed along the length of the barrel;
wherein the at least one flange is provided with a locking notch on an outer periphery of the flange;
wherein the locking notch comprises a receiving portion for receiving the material within the locking notch and a retaining portion for retaining the material within the locking notch of the at least one flange of the spool;
wherein an innermost end of the material is received within a feeding hole of the barrel of the spool, and wherein an outermost end of the material is received within the locking notch of the at least one flange of the spool;
wherein a spool drive flange of a spooler is operable for transferring rotational movement to the spool during a spooling process; and
wherein the spool drive flange has a covering that provides increased friction between the spool drive flange and the spool during the spooling process.
10. A spool configured for winding a length of a continuous, elongate, flexible material onto the spool, comprising:
an elongate barrel defining a longitudinal axis in an axial direction and having a length in the axial direction; and
at least one flange disposed along the length of the barrel;
wherein the at least one flange is provided with a locking notch on an outer periphery of the flange;
wherein the locking notch comprises a receiving portion for receiving the material within the locking notch and a retaining portion for retaining the material within the locking notch of the at least one flange of the spool;
wherein an innermost end of the material is received within a feeding hole of the barrel of the spool, and wherein an outermost end of the material is received within the locking notch of the at least one flange of the spool;
wherein a spool drive flange of a spooler is operable for transferring rotational movement to the spool during a spooling process; and
wherein a feeding unit of the spooler is operable for feeding the innermost end of the material to the spool and the spool drive flange is operable for winding the material onto the spool during the spooling process.
11. The spool according to claim 10 , wherein after completion of the spooling process the feeding unit moves the outermost end of the material in the axial direction beyond the at least one flange of the spool.
12. The spool according to claim 11 , wherein the spool drive flange rotates the spool in a generally circumferential direction so that the outermost end of the material is received within the locking notch of the at least one flange of the spool.
13. The spool according to claim 11 , wherein the feeding unit then moves the outermost end of the material in a generally radial direction so that the outermost end of the material is received within the locking notch of the at least one flange of the spool.
14. The spool according to claim 13 , wherein the spool drive flange then rotates the spool in a generally circumferential direction so that the outermost end of the material is received within the retaining portion of the locking notch of the at least one flange of the spool.
15. A method for retaining a length of a continuous, elongate, flexible material on a spool, comprising:
providing a spool having at least one flange provided with a locking notch;
winding the material onto the spool;
receiving an outermost end of the material within the locking notch provided on the at least one flange of the spool;
wherein the locking notch comprises a receiving portion for receiving the outermost end of the material and a retaining portion for retaining the outermost end of the material within the locking notch of the at least one flange of the spool; and
providing a feeding unit for feeding the material to the spool, wherein the feeding unit is movable in an axial direction to position the outermost end of the material beyond an outer periphery of the at least one flange of the spool in the axial direction.
