ABSTRACT:
For the individual, group and/or repeat change of schiffli-shuttles in embroidering machines, the schiffli-shuttle embroidering stations are shifted from centralized to decentralized shuttle stroke and vice-versa. Rotating motion of the driving shafts is converted into reciprocating motion immediately before each individual shuttle. The reciprocating motion is transmitted to entrainment rods and drive rods. The entrainment rods are rotated according to the repeat configuration so that such drive and entrainment rods are disengaged. By actuating the drive and entrainment rods, the individual schiffli-shuttles each are engaged with and disengaged from the centralized shuttle stroke. The schiffli-thread is cut, the schiffli-shuttle is arrested and the upper slider is opened or closed for group change. The empty schiffli-shuttle is removed and a loaded schiffli-shuttle inserted. In a particular embodiment for large embroidering machines with horizontal 4/4 arrangement, no conversion from centralized to decentralized shuttle stroke or drive is required.
