This invention relates to looms in which warp
yarns are manipulated by discs or cards to form
sheds into which ?lling yarn is inserted to pro

in disc looms, ‘which is superior to prior con

is concerned with a novel structure in which the
discs are supported in spaced relation and driven
in positive timed relation to other parts of the
loom. The new structure offers advantages over
prior disc assemblies, in that it is of simpler con
ber of discs by simple adjustments of parts of
the mechanism. In the new assembly, the discs
are provided with peripheral teeth and are
mounted between upper and lower shafts hav
ing pinions, the teeth of which mesh with the
