Patent

CA 2728755

An apparatus (140, 200, 300, 500) for feeding a wire The apparatus includes at least one pair of rotatable rollers (221, 222, 223, 224, 321, 322, 531, 532, 541, 542) and at least one curved or curvable force-generating element like a curved spring- type mechanism (510, 520). The at least one curved or curvable force-generating element is capable of applying a force via a proximal end of the at least one curved or curvable force-generating element to displace a first roller of the at least one pair of rotatable rollers towards a second roller of the at least one pair of the rotatable rollers to engage a wire there between. The apparatus further includes an adjustment mechanism (580) operationally connected at a distal end of the at least one curved or curvable force-generating element to allow adjustment of the applied force.

L'invention concerne un appareil (140 ; 200 ; 300 ; 500) pour alimenter un fil. L'appareil inclut au moins une paire de rouleaux rotatifs (221, 222 ; 223, 224 ; 321, 322 ; 531, 532 ; 541, 542) et ou moins un élément courbe ou courbable générant une force comme un mécanisme du type ressort courbe (510 ; 520). Ledit au moins un élément courbe ou courbable générant une force est capable d'appliquer une force via une extrémité proximale dudit au moins un élément courbe ou courbable générant une force pour déplacer un premier rouleau de ladite au moins une paire de rouleaux rotatifs en direction d'un second rouleau de ladite au moins une paire de rouleaux rotatifs pour engager un fil entre eux. L'appareil inclut en outre un mécanisme d'ajustement (580) relié de façon opérationnelle à une extrémité distale dudit au moins un élément courbe ou courbable générant une force afin de permettre l'ajustement de la force appliquée.
