(57) 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.
