I will now describe my method of producing a
?eece or double faced fabric on a sinker top knit
ting machine by carrying through the knitting
process necessary to produce one‘ course of the
?eece fabric shown in Fig. 10. For the purpose
of illustration, but not in limitation of my in
vention, I will describe the operation of a unit of
six successive" needles 24A to 24F, inclusive, as
shown in Figs. 5, 6, and 7.
10 'Needles 24A and 24C are elevated selectively
to receive inlay thread 3| from thread carrier 25
as shown in Fig. 5.
The latches of said needles
remain below knitting level L4 so that the previ
ous knitting loops remain on the needle latch.
15 At such point, cam 29, 'asshown in Fig. 4, actu
ates sinkers 2| so that inlay thread 3| lies .over
sinker nose N2, as shown in Fig. 12, between points
PI and P2 as shown in Fig. 11. '
Needles 24B, 24D, 24E and 24F do not receive
20 inlay thread 3| and rest at knitting level L4, as
‘shown in Fig. 12, whereas needles 24A and 240 are
drawn down by stitch cam (not shown) to knitting
level L2 as shown in Fig. 12.
Needles 24D and 24F are elevated selectively
25 to receive inlay thread 32 from the thread carrier
»25, as shown in Fig. 5. The latches of said needles
remain below knitting level L4 so that the previous
knitting loops remain on the “needle latch. At
such point, cam 29, as shown in Fig. 4, actuates
30' sinkers 2|, so that inlay thread 32 lies over sinker
35
thread '33, inlay threads 3| and 32 and previous
knitting loops, as shown in Fig. 9, said weft thread
33 becomes engaged with the loops of basevthread
34 although not forming a knitting loop therewith
and thus securing the inlay threads 3| and 32 to
theabase of the fabric.
.
I will now describe the sinker action in each
successive step of the formation of the fabric.
When needles 24A and 24C, take the inlay thread
3|, and are drawn down by stitch cam (not 10
shown), to level L3, as shown in Fig. 12, sinker
cam 29 withdraws sinker 2| so that the nose NI
of said sinker clears inlay thread 3|, said inlay
thread 3| being held on the nose N2 (Fig. 12) by
the needles 24A and 24C. Similarly, needles 24D
and 24F hold inlay thread 32 on the sinker
' nose N2.
When needles 24A to 24F, inclusive, are ele
vated to receive the weft thread 33, the needle
latches clear level LI and the sinker cam 29
pushes the sinker 2| forward so that the inlay
threads 3| and 32 are held against the shank of
the needles by the throat formed between the nose
N| and nose N2 of sinker 2|.
~
After needles 24A to 24F inclusive, receive the 25
weft thread 33, cam 29 withdraws sinker 2|, and
nose NI clears weft thread 33 so that said weft
thread 33 casts off inlay threads 3| and 32 held
on nose N2;
When needles 24A to 24F, inclusive, are raised
to receive the base thread 34, cam 29 pushes
nose N2 as shown in Fig. 12, and between points I sinker 2i forward so that inlay threads 3| and 32

Needles 24A, 24B, 24C and 24E do not receive upon nose N2 have been cast off by the weft
inlay thread 32. Needles 24A and, 24C remain at thread 33 and are pushed over the tops of the
knitting level-L2 and needles 24B and 24E rest needles so that such inlay threads 3| and 32 ride
at knitting level L4 (Fig. 12). Needles 24D and
24F are drawn down to knitting level L2 by stitch
against ‘the back of the shanks‘ of the needles
while the weft thread 33 rides against the front
of the shanks of the needles. All three threads

fore do not limit myself to what is shown in
the drawings and described in the speci?cation
but only indicated in the appended claims.
The method of producing the above described
fabric upon a sinker top knitting machine can
utilize spring needles as well as latch needles. I
therefore do not limit myself to the type of latch
needle described in‘ the speci?cation.

I do not limit myself to the above'described
combination of the number and texture of inlay
threads, weft threads and base threads. In other
words, one or more inlay threads, one or more
weft threads and one or more base threads may
be knitted in any combination to produce a wide
variety of knitted fabrics.

.
It is also within the scope of my invention to
produce a fabric upon a sinker top knitting
machine which has sinkers containing 2, 3 or
20 more levels to the corresponding 2, 3 or more
knitting planes.
I claim:
1. A method of knitting a fabric upon a sinker
top knitting machine with sinkers having two
steps characterized by the following sequence of
operations, namely, elevating needles so that the
latches of said needles are below the upper step
of said sinker, the already formed stitch loops
holding said latches against the shanks of the
30 needles, feeding an inlay thread to the hooks of
said needles and drawing said needles down so that
the hooks are below said step while said inlay

the already formed stitch loop.
2. A method of knitting a fabric upon a sinker
top knitting machine according to claim 1 where
in more than one inlay thread is fed to the hooks
of the needles at successive feed points to be cast
off by the Weft thread.
