JUKI LK-1900A-SS - Machine Design and Subclasses; Auto-Lifter and Stepping Motor; Workability and Operability; Subclass Model Variety

The LK-1900A model comes in five different subclass models, such as S type (standard), H type (for heavy-weight
materials), F type (for foundation), M type (for knits and knitted materials) and W type (with a large shuttle hook
for heavy-weight materials), to offer a choice according to any application.
The needle's penetrating force into the material has been increased. This provides an improved responsiveness to heavy-
weight materials for the H type machine.
The W type has adopted a large shuttle hook, which reduces the frequency of bobbin-thread changing to enable
highly efficient sewing work.
The machine is provided as standard with an auto-lifter that uses a new
stepping-motor system.
A wide choice of subclass models of LK-1900A
Excellent workability and operability.
The direct-drive head (with no belt), which is directly connected to a compact AC servomotor, achieves outstanding
responsiveness and improved stop accuracy. This head helps create a comfortable working environment with reduced
vibration and noise.
The arm section of the machine head is fitted with a hand pulley. This allows the operator to visually check the
needle entry points.
The sewing starting point can be corrected.
The sewing starting point can be shifted in the X/Y direction. This enables the correction of a sewing pattern in
accordance with the presser foot configuration.
It is also possible to change over the stroke of the auto-lifter from a one-step stroke to a double-step stroke, which offers
easier positioning of a material on the machine. For the double-step stroke, an intermediate stopping height can be
established on the operation panel.
The presser foot lift can be set to a maximum of 17mm by using the reverse-rotation needle-up function in combination
with the auto lifter mechanism.
