scribed with reference to FIGS. 17 to 20 is adhered so as
to obtain a similar looking as illustrated in FIG. 24.
At the moment of the ?nal transfer executed as de
loop 811 (:FIG. 28). The looping is then operated for
which the feeder is positioned at 83, said looping being
performed on the two needles 7'7 and 78; the feeder is
shifted outside the two sinkers, the stop having been auto
matically positioned in a suitable location. During the
scribed with reference to FIGS. 18 and 22, the thread
may in certain knitting machines engage the wrong side
of the needles 9‘2 and 94 (FIG. 25), so that, during the
transfer, the thread may have surrounded the needle 78a

the parasitic loop 79a thus formed, I knit a further row
It is easy to ascertain that if the threads 101 and 103
are cut and if the fabric is taken up outwardly, there is
no locking obtained in such a case since the needle 92
will cause the thread 101 to move out of the loops 97
and 98. Similarly, the needle 94 will cause the thread
to leave the loops 99 and 180'.
In other words, each time a needle carries a loop of 15
of loops on the needles 77 and 78, the feeder entering
then the position $5.3m. The thread is not caught by the
needle 7 8a and consequently the loop 7% is automatically
thread ahead of the terminal operative needle, the fact
of cutting the thread and taking up the fabric prevents
the locking of the loops to be obtained so that an unravel
ling becomes possible.
The knitting of a further course causes said loops to
drop since the thread 1M is not caught by the needle
92 during its rearward movement and similarly the thread
103 is not caught by the needle 94- by reason of the
stationary positions assumed by the feeders just beyond
the sinker located between the needles 92 and 93 and the
sinker located between the needles 94 and 35.
It should be remarked that, in the case illustrated of
the shifting movement eifected during the knocking over

eliminated (FIG. 30).
The following operation consists in transferring onto
the needle 78 the loop shown in FIG. 30‘ as carried by
the needle 77. The same stops serve again for the loop
ing and the locking is brought to an end by stopping one
of said feeders before these ?nal rows or courses; the
locking is obtained through a single thread which is pref
erable since the sliding of the thread for the ?nal opera
tion is thus furthered; when the loop is transferred from
the needle 77 onto the needle 75; and a further looping
is performed, the thread may again this time surround the
needle 78a (FIG. 31) and produce a further parasitic
loop 77a.
As illustrated in FIG. 31, the knitting of the further
loop ‘77b is su?'lcient for the loop "77:: to drop in the man
ner already disclosed for the loop 79a.
It will be remarked that if the parasitic loop, say 77a
