plication Serial No. 820,409, ?led June 15, 1959.
In knitting presentday full-fashioned stocking blanks,
yarns are fed to the knitting needles of a conventional
full-fashioned knitting machine by yarn carriers for a
plurality of courses to form the various parts of a stock
ing i.e., the welt, body, foot and reinforced areas of the
latter. At the completion of the knitting of each part of
the stocking and at the commencement of the knitting
of another part, yarns generally are changed by removing
carriers from or adding carriers to the knitting ?eld, an
relative position, i.e., the inclination, of the fabric in
the uncurler to the sewing mechanism. This position
can be controlled to some extent by machine adjustments,
but primarily is controlled by the inclination with which
the operator feeds the selvedges into the uncurler.
In conventional seaming machines the selvedges are
fed into the machine in a generally horizontal position.
The more upwardly inclined, however, i.e., the lower
the unseamed portion of the blank is held by the operator
in feeding it into the uncurler, the less fabric is included
in the seam, and consequently, the smaller and ?ner the
seam. Of course, the smaller the scam the ?ner the ap

careful manipulation on the part of an operator, however,
