FAQs
L'utilisation d'une machine à tricoter circulaire présente plusieurs avantages, tels qu'une productivité accrue, une qualité de point constante, la possibilité de réaliser des motifs complexes et une réduction de la fatigue physique par rapport au tricot manuel.
Bien que les machines à tricoter circulaires soient généralement sûres à utiliser, il est important de suivre les instructions du fabricant et de prendre les précautions nécessaires. Cela peut inclure le port de gants de protection et l’évitement de vêtements amples près de la machine.
