Machine has a shuttle drive with two longitudinal sections parallel to each other. A distance piece locks the two sections together and apart from each other. The two longitudinal sections are pref. of the same length and parallel to each other, using a tube or shaft with a circular or angular cross section. The drive pref. has a coupling for connecting to the propulsion and retraction units, with a holder and two openings for the ends of the longitudinal sections, and pref. an eyelet for the link to the drive units. The openings are pref. slitted sockets with a locking clamp. The distance piece is pref. a two-part hook, hwere the parts rest on the longitudinal sections, clamped together. The 2nd longitudinal section is between the 1st and the axes of the angled levers. The lever section linked to the 1st longitudinal section is a fork with tines and eyelets for a couplingpin to lock with thesection. It also has an opening for the 2nd section to pass through without contact witht he lever. The levers are of a lightweight material, such as Al. USE/ADVANTAGE - The system increases the work done by the shuttles of raised productivity without needle damage or faulty embroidery.
