MECHANISM FOR SIMULTANEOUSLY CUTTING TENSIONED BOBBIN THREADS AS ALL THE NEEDLE HEADS OF AN AUTOMATIC EMBROIDERING MACHINE

摘要

A mechanism for simultaneously cutting tensioned bobbin threads at all the needle heads of an automatic embroidering machine comprises a reciprocable draw bar which extends below all the needle heads. A cutter blade is provided under each needle head and is secured to the draw bar so as to be operable by the displacement of said draw bar. A fixed counterblade is associated with and located in spaced relationship to each cutter blade. A thread drawing lever is arranged to be operable by the draw bar at the same time as the cutter blade, for cooperation with a thread clamp fixedly mounted in spaced relationship to the thread drawing lever, said counterblade being located alongside the deflection path of said thread drawing lever.
