The
invention
- The
problem to be solved:
To knit racked pattern with about five
times higher productivity as the best
flat-bed knitters.
|
- Definition:
The invention is a knitting
machine with needle beds from segments
racked one after the other. The direction
of the racking is always opposite to the
relative moving of the cambox in
comparison with the needle beds. Since
the effect of the racking on one side is
the opposite to the other side, racking
the segments alternately on one and the
other side, results the same as racking
to and for on one side.

- Presentation:
Fig. 1. shows the sketch
of one detail of the needle beds of a
purl (as an example) circular knitter
according to the invention. No. 1 is
the upper No. 2 the lower bed. The
arrow shows the direction of the relative
moving of the needle beds in comparison
with the cambox. No. 3 is the
position of the racking the segments
(here after every ten segments). No. 4
– 8 illustrate the cam races.
No. 5 illustrates the moving of
the upper sliders, No. 6 shows the
moving of the lower sliders, No. 7
is the race of the transfer jacks. No. 4
and No. 8 illustrate the races
controlling the racking of the segments.
The selected needles move along the
continuous line, the non selected along
the dotted line of the curve 5.
According
to the example, while ten segments are
knitted, all the phases of a pattern with
row of transfer switches are completed:
i. e. transferring back the previously
non selected stitches (a),
knitting the new row of loops (b),
and transferring the new non selected
stitches, (By a purl knitter this is
composed of two parts: transferring all
stitches /c/, and transferring
back the selected stitches /d/)
and racking segment by segment.
As shown
in Fig.1., a group of ten segments
on one side are alternately exactly
facing the segments on the other side, or
are racked. So the machine is able to
knit as many row of transfer stitches in
one revolution as many ten-segments races
can form by the cams.
The
segments can be moved by simple
mechanisms from tappets and pins, or by
separate source of power (e. g.
electronic).
The
circular knitter has rotating cylinder
and take-down. The take-down has to be
“racked” as well in such a way, that
it must always facing the same segments.
In the needle beds some unoccupied areas
are required, extending minimum as many
needle distances as the total possible
needle distances of the racking on one
side. At this place the start and the end
of the row of loops can be established.
With an advantageous measurement of these
unoccupied areas, the yarn carriers and
the position of the cams can be changed
here as well.
|
- Application:
To knit outer garments with racked design
by coarsegauged (E4 – E10) circular
knitters. The machine could be a
large-sized two-bed circular knitter as
well.
|
- Advantages:
The circular knitter is able to knit the
same racked design with its high
productivity as the slow flat-bed
machines.
