on the inactive weft than that imposed by such weft"s attachment
to the fabric, they are included in this and indented subclasses
since they are most frequently found in conjunction with inactive
weft cutters (in which case they supply the support and restraint
which can no longer be provided by the fabric itself) and since
the additional function performed by those such devices not associated
