Abstract
A tufting needle (100) comprises a shaft (101) having a tapered formation (103) configured to penetrate and open a passage (105) in a resilient backing material (107). The needle (100) further comprises a filament lumen (109) that leads to an opening (117) proximal to the tapered formation (103), to guide a filament (111) through the passage (105) to create a tuft (113) at the resilient backing material (107). A cutting edge (115) is located at the opening (117) of the filament lumen (109) to cut the filament (111).
Claims29
A tufting needle comprising:
- a shaft having:
- a tapered formation configured to penetrate and open a passage in a resilient backing material from reciprocating movement of the tufting needle along a shaft axis of the shaft;
- and
- one or more engagement surfaces to engage with a rotating actuator, wherein the rotating actuator rotates the tufting needle around the shaft axis of the shaft;
- a filament lumen that leads to an opening proximal to the tapered formation, to guide a filament through the passage to create a tuft at the resilient backing material;
- and
- a cutting edge located at the opening of the filament lumen to cut the filament.
