Two selectable new-method
oiling mechanisms
The oil dropped from the hook and its surrounding sections into
the under-cover is filtered to remove dirt and dust and is then
returned to the oil tank. This method saves the effort of oiling and
reduces oil consumption.
The oil dropped from the hook and its surrounding sections into
the under-cover is not returned to the oil tank, but only clean oil is
supplied to the hook at all times.
The feed method can be easily changed over
The location of the oil tank has been changed to the inside of the
sewing machine through our re-investigation of the lubricating
method. As a result, space is secured under the bed surface to
facilitate changeover of the feed method between the "needle
feed" and "bottom feed" and changeover of the feed timing
(re-placement of the timing belt).
For the process of sewing light-weight materials or the like,
puckering has to be prevented. In this case, the feed method can
be changed over to the bottom feed through an easy adjustment
and change of the gauge. In comparison with the needle feed, the
bottom feed works to prevent puckering and enables sewing with
a lower thread tension.

The oiling method can be changed over as desired.
Gauge for tape attaching
(corresponding attachment classification code "T" for tape attaching; LH-3528A-F: Only the sewing machine for foundation)
Throat plate for tape attaching
The throat plate is designed with a
hollow on the side facing the
operator. This hollow
helps smooth
the feeding of tape.
Gauge for tape attaching (corresponding attachment classification code "T" for tape attaching; LH-3528A-F: Only the sewing machine for
foundation) The sewing machine is provided as standard with the gauge for tape attaching which is best-suited to the process for attaching tape to
foundation. The gauge for tape attaching consists of the throat plate for tape attaching, presser foot with guide and bed slide. The sewing machine
with the standard gauge can be changed to the tape attaching type sewing machine by changing the gauge with the gauge for tape attaching.
This reduces the
height when the
tape-attaching
holder is fixed on
the machine.
The LH-3528A supports, as standard, the feed type change-over function between
the needle feed and bottom feed.the feed type change-over function between the
needle feed and bottom feed. Contact JUKI for information on the models other than the LH-3528A.

The internal mechanism of the sewing machine has been thoroughly re-investigated to achieve
further improvement of maintainability and workability. JUKI does not cut corners on the quality
of those parts which are normally invisible, such as in the internal section of the sewing
machine. This represents JUKI's craftsmanship.
