摘要:
There is disclosed a multi-needle knotted-stitch quilting machine wherein the shuttles advantageously follow an arc-shaped path instead of the rectilinear reciprocating motion according to the prior art. This path normally extends for an operating angle α while a manual or automatic control is provided, after disengaging said oscillating mechanism, for performing an additional rotation β of the shuttles so as to make them accessible by having them come out from the fixed needle plate, also curved. The side guides of the shuttles, also arched, preferably have a rear extension to hold the shuttles when they have been rotated beyond the normal angle of oscillation α. There are also provided kinematic counterweight, pneumatic, hydraulic or spring devices for balancing the assembly and dampening the vibrations.

The invention relates to a device (51), for the preparation of a bobbin (11), for introduction into a shuttle of a shuttle machine, comprising a housing (53), with a bobbin seat (45) therein, with a seat axis (47) and embodied for housing the bobbin (11), parallel to the seat axis (47). At least one thread opening (55), leading out of the housing (53) from the bobbin seat (45) and a means for guiding the free bobbin thread end of a bobbin (11) on the bobbin seat (45) are further provided. At least one sensor (76) is also provided, which can determine whether a bobbin thread (23) extends through the opening (55). The device also comprises a junction (61), by means of which bobbins (11), which have a bobbin thread (23) detected, are passed on and the others, for which no bobbin thread is detected, can be picked out. On the preparation of bobbins (11) for the shuttles of a knitting machine the following steps are thus carried out: introduction of a bobbin (11) to a bobbin seat (45), search for the bobbin thread (23), extension of the bobbin thread end into a recognition zone (55), recognition of the presence of a thread (23), cutting the bobbin thread and sorting of the bobbins (11). A bobbin (11) for a shuttle on a shuttle machine is thus particularly suitable for such a process when the thread body (21) on the bobbin (11) is secured.

Das Schiffchen (3) weist einen Deckel (11) auf, an dem Achszapfen (9a,9b) angeformt sind. Der Deckel (11) ist im Bereich der Achszapfen (9a,9b) durch einen Schlitz (35) geschwächt. Diese Schwächung ermöglicht eine dauerhafte federelastische Lagerung des Deckels (11) innerhalb des Schiffchenkörpers (1).

The invention relates to an embroidery shuttle (1), comprising a bobbin carrier (20) and a bobbin (10), wherein the bobbin (10) comprises at least two spaced apart running surfaces (12, 14) and a bobbin body (16) extends between the running surfaces (12, 14). A rear thread (30) can be wound onto the bobbin body, wherein the bobbin carrier (20) has bearing surfaces (22, 24) for the running surfaces (12, 14), so that the bobbin (10) is rotatably mounted in the embroidery shuttle (1) about an axis of rotation (d). According to the invention, the bobbin carrier (20) essentially prevents a relative movement of the bobbin (10) along the axis of rotation (d).
摘要:
A shuttle embroidery machine having a shuttle guide has, for each embroidery position, a rear-side driver nail (11, 11') and a front-side driver nail (9, 9') for guiding a shuttle (5). The embroidery machine comprises, at each embroidery position, a shuttle race (3) and the shuttle (5) comprises a shuttle thread for embroidering. At the rear end (16) of the shuttle (5), a magnet (37) is fitted in a region on which the rear-side driver nail (11) acts. The rear-side driver nail (11) contains a magnet (35) or a ferromagnetic material, wherein the magnet (37) and the rear-side driver nail (11) have the same polarity, such that the shuttle (5) is repelled by the rear-side driver nail (11).
