●With the IP-100D, program stitching and cycle sewing can be set. By using this function, it is
possible to sew labels with constant-dimension sewing or to topstitch welt pockets while
automatically changing over the stitching type from straight stitching to zigzag stitching
according to the number of stitches desired. This contributes to improved working efficiency. In addition, multi-layer sewing, continuous
sewing, one-shot sewing and the beginning point of a scallop pattern can be programmed easily through the operation panel.
●A liquid crystal display has been adopted for the display unit. It displays settings for the stitch
shape, zigzag width and stitch base line position together on one screen with pictographs,
facilitating operation. At the time of creating/modifying a custom pattern, data can be entered
with the shape of the pattern visible on the display, leading to increased efficiency.
●Custom pattern data can be stored using the same SmartMedia that is widely used for
digital cameras.
●Stitch pitch in the normal (to +5) and reverse (to -5) directions
can be set on the panel.
●Display style of the custom pattern can be changed over
between the entire pattern display and partial pattern display.
●Normal/reverse feed amounts are established on the panel. This enables the machine to perform sewing with consistency, preventing
unevenness in the feed amount. Since the sewing conditions are established on the panel, they can be easily restored to a previous setting.
●Reverse feed stitch length can be increased and decreased directly on Reverse Feed Stitching Setting Screen of the peration panel, when the
reverse feed lever is press down. At the corners of labels, the stitch number per inch can be adjusted to sew the corners with consistency.
●For men's garments, the machine is used in processes such as topstitching for welt pockets,
sewing collar cloths and sewing labels. For ladies' garments, it can perform pattern stitching for
the collars and front bodies of jackets and blouses. In addition, original patterns can be created
using the custom pattern feature, enabling the machine to be utilized for a broader range of uses.
●In addition to the conventional eight types and 14 patterns of zigzag stitching, the machine is
able to perform T-shape stitching and covering stitching. As a result, the machine is equipped as
standard with a 14-type and 20-pattern sewing capability. Furthermore, the machine is able to
perform condensation stitching (for reverse feed stitching) at a high speed during sewing to
dramatically increase the operating rate of the facility.

The machine is built around the newly developed LZ-2290A-7 machine head.
In addition to the conventional types of stitching, the machine is able to perform
T-shape stitching and zigzag pattern stitching to broaden its range of applications.

●The machine comes with a direct-drive type motor. As a result, the
machine quickly starts and promises an upgraded stopping accuracy and
excellent responsiveness.
●The arm of the machine head is longer than a normal arm by one size,
offering a longer distance from machine arm to needle to facilitate
handling of the sewing material on the machine, leading to improved
workability.
●Thread trimming mechanism notable for its simple structure and extremely
reliable performance. The knife-sliding method employed by the thread
trimmer guarantees that the thread is cut regardless of the needle throw
position.
●The machine is provided as standard with a micro-lifter screw. This helps
prevent material slippage or damages when using elastic materials.
●Since the hook and needle bar is lubricated with a minute-quantity of
lubricating oil, sewing products are rarely stained with oil.
●The zigzag width and feed amount are stored on a stitch-shape
basis. It is therefore not necessary, after changing the stitch
shape, to re-adjust it. For a custom pattern, data can be
programmed on a stitch-by-stitch basis.
●The magnet operating noise is virtually silent, even at the
time of changing over the sewing direction between normal
and reverse feed directions. This contributes to the
achievement of a comfortable working environment with little
noise.
●The feed mechanism is controlled with a stepping motor to enable
continuous sewing at a high speed. The machine achieves the
world's highest sewing speed of 4,000rpm even when performing
pattern sewing, including T-shape stitching and condensation
stitching, dramatically increasing productivity. In addition, the
machine retains stitching shapes with consistency (the maximum
sewing speed differs depending on the sewing condition).

−
This handy switch is used to control various functions*. It is
most effective when operating the machine in a standing
position. (＊Needle up/down correction, 1-stitch correction, reverse-
stitch correction, auto lifter and thread trimmer, etc.)
The amount of tape to be fed can be adjusted in accordance
with the sewing speed of the machine. It is adaptable to
processes for attaching reinforcement tape, attaching elastic
tape or lace to foundation.
Applies tension to desired portions of the tape fed from a
tension-free tape puller. The device is started/stopped by
operating the knee switch. This increases operator
productivity without interrupting the sewing work.
The aforementioned parts are used when a lockstitching type
presser foot is installed on the machine.

*1 The maximum sewing speed is factory-set to 4,000 rpm at the time of shipping (depending on the region to which the machine is to be shipped).
*2 The maximum sewing speed of the machine varies depending on the zigzag width and feed amount settings.
・Since the speed is controlled with the zigzag width and feed amount per stitch, it is thus limited by the zigzag width and feed amount settings for a sewing pattern.
・The sewing speed should be appropriately set according to the sewing product and process.
*3 The maximum zigzag width has been factory-limited to 8 mm, at the time of standard shipping.
