Electronic lockstitch pattern tacker with treble hook
Attractive and accurate sewing finishes for extra-heavy materials
This electronic pattern tacker is ideal for sewing heavy and
extra-heavy materials such as seatbelts. It gives excellent
economy, with shorter cycle times and easier maintenance.
KE-484C
• Knife method cuts even extra thick threads
accurately.
• Pneumatic drive wipes the thread smoothly.
• Stable thread tension release improves
sewing performance.
• Stitch patterns can be changed easily.
A variety of thread types up to #0 can be cut accurately.
• A knife method is used for thread trimming. When the knives are
meshing, the movable knife and fixed knife are driven by a
pneumatic cylinder. Extra thick threads of up to #0 can be cut
accurately regardless of the material of the thread.
• The speed of the knife is controlled by a pneumatic cylinder
which reduces excessive spinning of the bobbin during thread
trimming. The thread is held securely from the start of sewing so
that stable seams are created.
• Unlike the heat cutting method, the knife method does not require a heater to be warmed up, so it
reduces cycle time. It also saves electricity costs and makes temperature control unnecessary. In
addition, the knives are much more durable than the heater wires, so that the knives can accurately cut a
greater variety of threads. They are also easier to maintain.
• The thread wiper is also driven by a pneumatic cylinder. The upper thread can be wiped accurately even
under conditions where the thread is difficult to pull out of the material.
Optimized thread tightening creates attractive sewing finishes.
A pneumatically-driven thread tension release mechanism has been adopted. Compared to cam-type
methods, this mechanism provides much stronger thread tension. In addition, the thread tension discs
open and close accurately even when high tensions are applied to the upper thread, so that the upper
thread trailing length is kept at a constant length and problems at the sewing start are prevented. Stable
and accurate thread tightening is provided even under high load conditions, so that good thread tightening
can be obtained even when sewing through several layers of material, thereby increasing the range of
sewing applications. Plus, a new thread take-up mechanism ensures that the thread tightening is optimum
for the material being sewn.

Attractive and accurate sewing finishes for extra-heavy materials
Superb ease of operation greatly increases working efficiency
Increased material penetration force
The adoption of an inside motor allows the
operator to easily increase the torque to the
optimum level for the article being sewn simply by
replacing the pulley and PROM. (Available by
special order)
Thread pulling-out is prevented at the sewing start
A pneumatic-type thread take-up device is
equipped as standard. This device allows you to
easily set the thread feeding length at the sewing
start to the optimum length (0 to 20 mm) for the
material. Allowance can also be made for the
thread trailing length to prevent the thread from
pulling out at the sewing start.
No thread staining
The oil supplied to the rotary hook is kept clean at all
times, which helps to prevent staining of the thread.
Simple pattern changing
Because this is an electronic pattern tacker, the
sewing patterns can be easily changed just by using
the operation panel. Changes to line organization
can also be made easily.
Abundant data storage capacity
Max. No. of stitches is 20,000. Up to a maximum of
16 user programs can be created, each with its own
sewing pattern, enlargement ratio and sewing
speed.
Pattern enlargement and reduction is also easy
Enlargement and reduction of the sewing patterns
can be set at a touch using the operating panel.
The ratios can be entered either as a percentage or
in length (mm). (determined by DIP switch setting)
Cycle sewing
Up to 4 cycle sewing patterns can be programmed.
Max. 15 patterns/cycle can be programmed.
Presser foot lift amount
The presser foot lift amount is a maximum 25 mm.
Even extra thick materials can be inserted and
removed with space to spare. In addition, the
presser foot lift amount can be set to different
heights to match the working requirements.
Smooth pedal operation
The foot switch needs only a light pedal pressure to
operate. This reduces the operator’s working fatigue
and gives better work efficiency.
Easy-to-use independent operating panel
The operator can select whichever position is
easiest to use.
Accurate home position detection
The home position sensor incorporates a nonoptical proximity sensor, so the sensor is not subject
to operating errors from oil or dust, and cleaning oil
and dust from the sensor are also unnecessary.

Reduced bobbin replacement frequency
The triple capacity rotary hook allows 3 times the lower thread to be wound on compared to standard
bobbin. This reduces the frequency of bobbin changes and also reduces overall cycle time.
Excellent durability
Bearing brackets have been adopted as the needle bar and thread take-up shaft brackets. These bearings
ensure stable and accurate performance with excellent durability, so that stable sewing is possible using
threads of up to #0 in thickness. They improve reliability when sewing under heavy loads, and increase the
range of sewing possibilities.
Built-in Motor system
Improved productivity
An built-in motor system that is ideally suited to cycle
sewing machines has been adopted. This system
reduces overall cycle time.
Low noise and low vibration
Integration of the motor and the machine head and the
adoption of a timing belt make sewing machine
operation much quieter and reduce machine vibration.
Easier maintenance
Periodic adjustment of the belt tension and adjustment
of the motor position are no longer necessary. The
machine head can also be tilted back to carry out
adjustments without the need to remove the belt cover.
No contamination of the material
The adoption of a timing belt eliminates the problem of belt shavings soiling sewing products.
Thread breakage detector
The automatic stop is activated and a buzzer
sounds to warn the operator when a thread
breakage is detected.
