I. OUTLINE
1. Introduction of KH-300
The KH-300 is a flat knitting machine, developed and manufactured in
keeping with the following concepts.
▓Compact ▓ Light-weight
▓ Space-saving ▓High-performance
▓ Efficient ▓ Economical
One feature is the variable stroke steplessly in proportion to the knitting
width, thereby eliminating wasteful motion.
A large memory capacity is provided in order to produce variable knitting
patterns.
The most advanced techniques are adopted high speed USB Flash Drive
and 3.5 inch floppy disk drive.
The take-down device consists of main roller and sub roller. The sub-rollers
under the needle beds gap stabilize knitting for better control of the fabric.
The top tension with knot catcher, lamps and moveable sinker equipment.

7.1Top tension
a. Electronic top tensions are easy to thread the yarn through. The large knot
causes machine stop. The small knot causes slow speed then
automatically resume at set speed.
b. Top tension springs should have the correct tension, the opening of the
knot-catcher must be set according to the yarn count that is being knitted.

7.2Fabric take-down system
In principle of the take-down tension strength must be small and average.
The take-down system is controlled by torque motor.
Each roller can be adjusted individually. The pressure of roller gets larger
and the speed of take-down gets faster.
To detect fabric falling or wraparound, there is equipped with a press-off
detector in the front of roller and a fabric roll-up detector in the back of
roller.
The machine will stop automatically when the fabric happens fall or wraparound.

7.4 Yarn feeder
The position of carrier is adjusted according to the desired knitting width,
correctly make yarn feeder beside the end working needle by 10 mm. The
yarn feeder must be in the central position between front and rear needles,
also check its height refer to Fig.7.4.1. When work several yarn feeder in
knitting, the position of carrier should be adjusted to make each yarn feeder
not be overlapped, it avoids damage of the parts. The yarn carrier on rail must
be adjusted in an easy movement, and adjustment refers to Fig.7.4.2.

7.10 Racking mechanism
The rear bed can be racked four（4）inch(left right each 2 inches), the
initial position”0”. See the left selvedge of needle bed, the corresponding
position that the first needle of rear is on the left hand side of the first needle of
front. As shown in Fig.7.10.1.In editing instruction you can choose the left
racking or the right racking by one pitch.
Left rear
Left front
In each racking position the rear bed and the front bed must be kept in correct
corresponding relation. You check it with pushing one front needle to tuck
position, the hook of front needle and the knock-bit of rear bed should be at
the same position.
Fig.7.10.1 Initial position of needle bed
If there has racking instruction in programming, you must enter the test mode
to rack the needle bed in the set position before you execute run, and make
sure the racking mechanism is matched your programming.
If the corresponding position of needle bed is not proper, loosen the stepped
screws and adjust the rear bed to correct position, then tighten the stepped
screws after adjustment. Refer to Fig.7.10.2.
