LZ-2282N
High-speed, 1-needle, Lockstitch,
Standard Zigzag Stitching Machine with Lower Knife
Productivity is dramatically increased
The machine incorporates a built-in lower knife that trims only the lower
material. This allows the machine to simultaneously attach lace to the
body of the foundation and trim only the body during processes to attach
lace to the bottoms or tops of slips or to the joint seam lines of shorts.
The machine demonstrates consistent trimming
performance
The knife is driven by a motor that runs independently from the sewing
machine motor. With this feature, the knife can continue to run at a
high speeds during trimming even when the speed of the machine is
reduced during startup or when sewing curved sections. Furthermore,
the knife is placed just beside the needle to provide a constant trimming
width even on the curved sections.
Upgraded operability
Since the knife stops at the upper position of its stroke at all times, the
material can be smoothly placed on the machine. The knife height can
easily be changed by operating the lever mounted on the front face of the
machine in accordance with the type of material to be used. If the knife
height is set at 0 (zero), the working surface of the machine will become
flat. In this case, the knife-driving mechanism will be automatically turned
off, permitting machine use for typical standard zigzag stitching operation.
