The horizontal-/vertical-feed mechanism is controlled by motor. The sewing machine can be adjusted with ease by operating the operation panel.
Change in feed timing has been a time-consuming operation. For the LZ-2290C, however, feed timing can be changed with ease by operating the operation panel. It is therefore possible to set the feed timing so as to produce the seam quality (soft⇔standard⇔hard) that is suited to the process. In addition, the feed locus can be changed to that for preventing material slippage. With these improvements, the sewing machine provides further enhanced responsiveness to materials.
The LZ-2290C is the world’s first sewing machine that comes with rotary-type active tension. Conventionally, it has been difficult to adjust the thread tension when the remaining amount of bobbin thread has reduced. This sewing machine, however, is able to correct and stabilize the thread tension by means of the active tension. In addition, the thread tension can be corrected according to the sewing speed, thereby contributing to improved seam quality.
Thanks to the adoption of the active presser foot, the presser foot pressure can be corrected according to the sewing speed, and jumping during high-speed sewing can be suppressed. (Select automatic foot lifter AK156 type at the time of factory shipment).
The LZ-2290C is provided with a multi-layered portion detection device. Sewing conditions on a flat portion and that on a multi-layered portion of material can be respectively set. As a result, conventional problems that are likely to occur when sewing a multi-layered portion of material such as stitch gathering and loose stitches can be prevented.
The sewing machine is provided as standard with 11 types / 20 patterns of basic stitch shapes. Sewing patterns such as zigzag stitching, T stitching, and pattern sewing can be selected on the new operation panel of the main body, thereby substantially increasing the facility operation rate. In addition, a sewing pattern can be created for the brassiere sewing process for sewing a brassiere while skipping its bone portions. This also helps increase productivity. For men’s garments, the machine is used in processes such as topstitching for welt pockets, sewing collar clothes, 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.
A “Two-way” contactless communication for parameter adjustment data can be conducted with the sewing machine by a commercial Android terminal. This feature allows sewing machines in a sewing line to be uniformly set and status checked quickly, thereby contributing to stabilization in product quality. Control panel is standardized with USB ports, promising simplicity in data management and system updates.
In the application, there are items of management setting (terminal registration), sewing machine data (sewing data), problem-solution chart. In the problem-solution chart, we can generate production graphs, the availability chart, etc. for each acquired sewing machine data so it can be used for checking the current situation and analyzing it.
