Brother KE-484C Sewing Machine User Manual


 
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 non-
optical 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.
