ABSTRACT
The production of knitted goods in the light industry has entered a phase of rapid development after the 20s of the
last century. Today, the global production of knitwear accounts for more than 35% of total textile products. This figure
is expected to be above 50 per cent by 2025. This, in turn, requires the introduction of modern technologies in
enterprises, based on the demands and needs of consumers for the quality of knitted products.
KEYWORDS
Knitting machines, knitted products, knitting machines.
INTRODUCTION
Almost all products made of fabrics are made of
knitted fabrics.
At present, knitting enterprises are equipped with
modern knitting machines, which are controlled by a
program with high productivity and technological
capabilities. Modern knitting machines include the
following technical and economic indicators:
High productivity of knitting machines;
Possession of high-tech icons (knitting earrings and
knitted fabrics and coupons for outerwear and
underwear, production of knitted products used in
machinery and other sectors of the economy,
simultaneous use of different types of yarn in
machines);

High efficiency of raw materials and low labour
costs in the production of knitted garments
compared to the production of garments from
fabrics;
Ease of working conditions and high quantity of
product per unit area [1-7].
Circular double-needle knitting machines with modern,
wide technological capabilities and high class occupy a
significant place in the enterprises of knitwear
production operating in the country. Double-needle
knitting machines occupy a significant place among
knitting machines due to their versatility, and high
productivity and is equipped with electronic control
and monitoring devices. In the knitting industry, the
modern circle specializes in double-needle knitting
machines with tires and double-tires (interlock), as well
as knitted and crocheted knitwear. In addition, the
prevention of accidents in the production of knitting
weaving machine safety requirements [8-11].
We analyzed the circle by studying the SMARTC1
knitting machine KONMEIT model with two needles
and observed that the loop formation is performed by
distribution or in series (Fig. 1).
Figure 1. General view of SMARTC1 knitting machine of KONMEIT type with two needles in a circle.
When we constructively analyze the circular double-
needle KONMEIT SMART C1 knitting machine, we can
see that it consists of the following main parts [12-14]:
Spinning part provides the ring-forming members
with thread. The threading mechanism consists of
a spool located at the top of the machine needles
and four special racks mounted around the
machine to mount the coils. The threading section
is equipped with an eye guide that allows easy

unravelling of the threads in the bobbin, devices
for directing the threads to the needles, adjusting
the thread tension and controlling the continuous
supply of thread. According to the function of the
threading part, the loop-forming process in the
weaving process is to provide the members with
the thread at the same time;
Knitting part The needles with the tongue are
attached to the circular needle in a horizontal and
vertical position. The cylinder needles and washer
needles are placed perpendicular to each other,
and the needle together with the needles performs
a circular motion using an electric motor around
the main shaft. The loop-forming members around
the needle (an electromagnetic pulse mechanism
that controls the threading, distribution, finishing,
throwing, and movement of the needles) are
attached to the machine table in a stationary
position relative to the needles. As a result of the
circular motion of the needle to the members of
the loop formation, the thread to the needles is
provided using special devices;
Pulling part located at the bottom of the machine,
is equipped with three traction and wrapping
shafts as well as an extension box that provides
rotational movement of the shafts. The gearbox
consists of a gear that adjusts the rotational
motion, a gear wheel, a gear rail and bevel gears.
Pull the knitted fabric continuously according to
the function of the pull-up wrapping part and wrap
it on a special roller at the same tension.
The spinning system on the circular double-needle
KONMEIT knitting machine consists of a mechanism
and devices attached to a spool located at the top of
the machine needle, as well as four special racks
mounted around the machine to install the coils (Figure
2).

yarn, 4-cross, 5-belt, 6-pulley, 7-belt tensioning device.
In the sequential process of loop formation, the rings
are formed by a series of needles between the two
needles. The active needle that forms the loop by
taking the rings of needles directly from the thread
feeder is the passive needle that forms the ring from
the thread of the active needle rings of the needles
(Fig. 3).
