Abstract

A filament drive mechanism (22, 122, 222, 322, 422, 500) comprising a rotatable component (36, 136, 236, 336, 436, 532) comprising a central hole (46, 146, 346, 446, 546) defined at least in part by an internally-threaded surface (48, 148, 348, 448, 548), and is configured to receive a filament strand (24) through the central hole (46, 146, 346, 446, 546) to engage the internally-threaded surface (48, 148, 348, 448, 548) with the filament strand (24). The filament drive mechanism (22, 122, 222, 322, 422, 500) further comprises at least one rotation mechanism (534) configured to rotate the rotatable component (36, 136, 236, 336, 436, 532), thereby allowing the engaged internally-threaded surface (48, 148, 348, 448, 548) to drive the filament strand (24) through the central hole (46, 146, 346, 446, 546) of the rotatable component (36, 136, 236, 336, 436, 532).
