FIELD OF THE INVENTION
[0001] The present invention relates to a yarn guide of a knitting machine, and more particularly
to a yarn guide of a knitting machine that assists two yarns to form a counter wrap
knitting status.
BACKGROUND OF THE INVENTION
[0002] A towel fabric knitting method is a prior art in the textile industry, and the method
includes a wrap knitting ring and a counter wrap knitting ring to wrap the bottom
of a yarn ring. For example, the inventor of the present invention has filed and obtained
R.O.C. Patent Publication No. M247596 that discloses a single-sided counter wrap knitted
towel sinker plate of a circular knitting machine, and the sinker plate is installed
at the yarn looping position of the circular knitting machine with an inclined angle,
and the sinker plate comprises a nose section, an abdomen section coupled with an
end of the nose section, and a throat section coupled to another end of the nose section,
and one side of the throat section includes a first distal surface and the abdomen
section includes a second distal surface. When the sinker plate is installed at the
circular knitting machine, the first distal surface is substantially in a horizontal
plane and the second distal surface is an inclined plane, and a yarn loop is propped
up to the highest horizontal position by the nose section.
[0003] R.O.C. Patent Publication
No. 454770 has disclosed an improved needle tracks of a double-sided towel counter wrap knitting,
which primarily designs the tip of a half needle section of a needle track of a knitting
machine to be elevated, so that the knitting needle can operate with two sinker plates
of different shapes to move alternately along the needle track, so as to hook and
pull the wool loop and the base yarn to constitute the double-sided towel counter
wrap knitting. When the knitting needle travels to the elevated area at the tip of
the half needle section, the knitting needle is lifted by the elevated area to avoid
the needle latch of the knitting needle from being squeezed by the sinker plate which
will cause a broken yarn. R.O.C. Patent Publication
No. 376909 had disclosed a novel caltrop-shaped structure of a counter wrap towel knitting machine
comprises a first caltrop-shaped module, a second caltrop-shaped module, a third caltrop-shaped
module, a fourth caltrop-shaped module, a fifth caltrop-shaped module, a sixth caltrop-shaped
module, a seventh caltrop-shaped module, and an eighth caltrop-shaped module, and
one of the first, second and third caltrop-shaped modules can be selected to fit the
size of the sliding track and different sizes according to the user's requirements,
so as to fine tune the yarn to have the desired length of the wool loop.
[0004] From the description above, a sinker plate or a caltrop-shaped module is used regardless
of the warp knitting or counter warp knitting, and thus making the overall mechanical
design more complicated and difficult. Therefore, it is an important subject for manufacturers
in the textile field to design a simple mechanism for the wrap knitting or counter
wrap knitting.
SUMMARY OF THE INVENTION
[0005] The primary objective of the present invention is to install a yarn guide plate on
a side of a knitting needle, so that a wool yarn with an additional effect can be
knitted into a base yarn in a counter wrap knitting status to produce the base fabric.
When the wool yarn and the base yarn are hooked, the yarn guide plate presses the
base yarn to the bottom of the wool yarn to define a counter wrap knitting status
of two yarns, and thus achieving the effect of fixing the bottom of the wool yarn
into the base fabric.
BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a perspective view of the invention;
FIG. 2 is an exploded view of the structure of the invention; and
FIGS. 3A to 3D are schematic views of part of the assembly of the invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0007] The present invention will now be described in more detail hereinafter with reference
to the accompanying drawings that show various embodiments of the invention.
[0008] Referring to FIGS. 1 and 2 for the perspective view and the bottom view of the present
invention, a structure of a yarn guide plate 50 of a knitting machine comprises a
needle disc and a needle barrel (not shown in the figure) which include a plurality
of knitting needles 10 and a plurality of entry knitting needles 20 respectively,
and the plurality of knitting needles 10 and the plurality of entry knitting needles
20 are installed alternately, so that the plurality of knitting needles 10 and the
plurality of entry knitting needles 20 can carry out the weaving job of a fabric having
a yarn ring surface on one side by the needle disc and the needle barrel, wherein
the fabric includes a base yarn 40 for forming the base fabric of the fabric (not
shown in the figure) and a wool yarn 30 for forming the yarn ring surface. In the
figures, the wool yarn 30 is disposed at the external end of the knitting needle 10
and hooked to the wool yarn 30 by a needling action. Since the knitting needle 10
and the entry knitting needle 20 are installed alternately, therefore when the two
knitting needles 10 hook the wool yarn 30, the wool yarn 30 will be sheathed onto
the entry knitting needle 20 to form a yarn ring 31. After several times of the weaving
process, the yarn ring 31 forms the foregoing yarn ring surface. The needle disc and
the needle barrel continue moving to drive the knitting needle 10 which is hooked
with the wool yarn 30 to hook the base yarn 40 and carry out the base fabric knitting
procedure. In the meantime, the bottom of the yarn ring 31 is woven into the base
fabric, so as to achieve the effect of fixing the yarn ring 31.
[0009] The key point of the present invention resides on that the counter wrap knitting
method is used to weave the wool yarn 30 into the base fabric. Referring to FIGS.
2 and 3A to 3D for the explode view and schematic views of the movement of the present
invention, the knitting needle 10 includes a yarn hooking section 101 for hooking
yarns and a needle latch 102 for movably including yarns therein, and one side of
the knitting needle 10 has a yarn guide plate 50 with an inclined surface 51, so that
the needle disc can be shifted to drive the wool yarn 30 and the base yarn 40 into
the yarn hooking section 101 and a first yarn hooking position of the needle latch
102. The needle disc continues shifting to enter the base yarn 40 into a second yarn
hooking position of the yarn hooking section 101, and the yarn guide plate 50 presses
the base yarn 40 at the first yarn hooking position (as shown in FIG. 3A) and the
knitting needle 10 is drawn back by the continuous movement of the needle disc, such
that the base yarn 40 advances gradually towards the yarn hooking section 101, but
the base yarn 40 is still pressed by the inclined surface 51 of the yarn guide plate
50 to attach the surface the knitting needle 10 to advance (as shown in FIG. 3B).
Until the base yarn 40 at the second yarn hooking position enters the yarn hooking
section 101 and the needle latch 102 is covered and sealed, the base yarn 40 will
be located under the wool yarn 30 (as shown in FIG. 3D). In the meantime, the wool
yarn 30 is woven into the base fabric. The wool yarn 30 is at the top and the base
yarn 40 is at the bottom and the status of weaving the base fabric which is the feature
of the counter wrap knitting or the counter wrap knitting. The base yarn 40 weaves
the wool yarn 30 into the base fabric on another side opposite to the yarn ring 31,
and thus achieving the effect of fixing the bottom of the yarn ring 31 to the wool
yarn 30. If the yarn ring 31 is pulled, the yarn ring 31 will not be loosened or fallen
out from the base fabric easily.
[0010] While the invention has been described by way of example and in terms of a preferred
embodiment, it is to be understood that the invention is not limited thereto. To the
contrary, it is intended to cover various modifications and similar arrangements and
procedures, and the scope of the appended claims therefore should be accorded the
broadest interpretation so as to encompass all such modifications and similar arrangements
and procedures.
