JACK JK-58750C
Industrial twin-needle lockstitch machine with an integrated 750 W servo motor, needle feed and needle disengagement. Designed for medium and heavy fabrics.
The JK-58750C is a variant of the JK-58450C and JK-58750C series with enlarged horizontal hooks and a stitch length of up to 7 mm. It is indispensable when you need two parallel seams side by side: for bedding, workwear and jeans. Any needle can be disengaged with a convenient lever, so it is easy to turn a seam at a right angle.
The needle mechanism and the feed dogs work in sync, so the fabric layers do not shift even on long seams. The machine trims the thread automatically at the end of an operation, lifts the presser foot and positions the needle, and the backtack is fully programmable. Supplied with a table.
The machine is made under licence from the Japanese corporation BROTHER and is an equivalent of the BROTHER T-8750C.

Series variants
In this series you can choose a twin-needle machine with or without full automation, and with or without needle disengagement. The table shows all variants by specification.
What has been improved
Hooks twice as large
They hold much more thread, so the machine needs re-threading less often and sews twice as long on one setup.
Larger working area
More space around the needle
Increased distance between the working area and the machine body.
Wider feed dog adjustment
Increased adjustment range of the feed dogs.
Simpler hook adjustment
The new system is more reliable and simpler.
Hook protection
Sealed covers protect the hooks from dirt and extend their service life without extra maintenance.
Closed lubrication system
The oil is not contaminated by fabric dust and keeps its properties for a long time, while the fabrics being sewn stay clean.
Bearings instead of bushings
There are no bushings to wear out, so the machine lasts several times longer.
Adjustable thread tensioners
The machine can be readjusted from thin to heavy fabrics.
Floating presser foot
Adapts automatically to the thickness of the fabric being sewn.
Graduated presser foot pressure
Together with improved stitch density adjustment.
More reliable thread trimming
A newly designed electromagnet gives greater reliability and less frequent maintenance.
Steel shafts
Low vibration and stable operation.
Reinforced belt drive
Less noise and vibration, more stable and cleaner operation.
Needle disengagement
Any needle can be disengaged with one lever, which is handy when turning right-angle corners.
