LK-1850 SERIES
In addition to the capability of low-tension stitching, the prevention of
loose stitches at the start and end of sewing using synthetic threads is
assured. The use of JUKI's unique thread trimming system, coupled
with the low-tension sewing capability, have further upgraded the
sewing performance. The formation of even stitches of high quality is
assured regardless of the type or size of threads used.
The lower clamping plate has been flattened and the feed cam has been
made compact by limiting the sewing size and the number of stitches.
The result is a wider sewing area.
lift is as high as 17mm. By these improvements, a workpiece can be
handled more easily without concern about the workpiece becoming
caught in the cam.
The machine features a higher sewing speed and shortened cycle time,
and is provided with a new smooth thread winder.
various other improvements that lead to higher efficiency, including a
pedal that requires low pedaling pressure, a work clamp foot that
ensures free finger action, and a face plate that allows the needle entry
point to be seen at a glance.

*1. Pedal-pressure-decreasing unit:
It mechanically actuates the pedal, to reduce operator's
fatigue in raising the work clamp foot, etc. Since this is a
mechanical feature, the operator cannot stop the work
clamp foot at its intermediate position or lower it slowly.
*2. P type unit:
The work clamp foot is raised or lowered by the lever system
in accordance with the amount of pedal depression.
This feature is very advantageous for a process that requires
accurate positioning of the material.
Furthermore, the work clamp foot
