Abstract

Un appareil de broderie, qui peut également être appelé machine à coudre, appareil de couture et/ou machine à broder dans la description, est généralement configuré pour créer des embellissements de couture, tels que des motifs et/ou des conceptions sélectionnés par l'utilisateur, sur des pièces à travailler (p. ex., des textiles et des tissus). L'appareil de broderie peut généralement comprendre un mécanisme d'aiguille et un mécanisme de pièce à travailler. Une aiguille (p. ex., une aiguille filetée) peut être couplée au mécanisme d'aiguille et une pièce à travailler peut être couplée au mécanisme de pièce à travailler. Le mécanisme d'aiguille, selon divers modes de réalisation, est généralement configuré pour déplacer l'aiguille vers le haut et vers le bas (p. ex., dans un mouvement de va-et-vient commandé) dans un sens sensiblement vertical de sorte que l'aiguille se déplace dans et hors de la pièce à travailler.
