| (54) | Yarn traverse apparatus |
| (57) A yarn traverse apparatus which prevents adjacent blades from interfering with each
other and breaking even if blades of any of traverse mechanisms are out of phase and
which allows the traverse mechanisms to be installed and removed easily. The yarn
traverse apparatus includes a plurality of traverse mechanisms arranged so as to be
adjacent to one another with respect to a plurality of juxtaposed bobbins. Each traverse
mechanism has a set of two shafts arranged upstream of a corresponding bobbin. The
two shafts are orthogonal to a shaft of the corresponding bobbin and rotate in opposite
directions. Each of the two rotating shafts has blades attached thereto, the blades
serving to traverse a yarn. Each traverse mechanism is arranged to form two surfaces
of rotation when the blades attached to the set of two rotating shafts rotate. The
plurality of such traverse mechanisms are arranged so that loci of rotation of the
blades belonging to adjacent sets partially intersect. When yarns are traversed by
such yarn traverse apparatus, surfaces of rotation formed by the blades attached to
the two shafts of rotation of each of the adjacent traverse mechanisms are uniformly
as well as sufficiently inclined with respect to a surface formed by a yarn in a single
direction as viewed in vertical directions, so that the surfaces of rotation formed
by the blades belonging to the adjacent sets will not interfere with each other. |
