Semi-dry head, 2-needle Lockstitch Machine
The Juki LH-3568A-7 (Juki LH-3500A Series) sewing machine with organized split needle bars is the only sewing machine in the industry that comes with the semi-dry head. It helps reduce poor-quality products due to oil stains even in the case of product items which have corner stitching sections.
Description
Semi-dry head, 2-needle Lockstitch Machine
Adoption of the direct-drive mechanism enhances energy conservation and workability, and increases the needle’s material penetrating force.
The Juki LH-3568A-7 (Juki LH-3500A Series) has made further progress. This is the cutting-edge model 2-needle sewing machine which comes with substantially enhanced mechanisms such as the direct-drive mechanism, semi-dry head, new thread tension control mechanism and improved oiling system.
A semi-dry head is now installed in all of the models of the LH-3500A Series.
All models of the Juki LH-3500A Series are provided with a semi-dry head to eliminate staining with oil from the frame (the needle bar part).
Responsiveness to materials has been thoroughly investigated to improve “seam” quality.
A thread tension control mechanism has been developed for each type of sewing machine in order to achieve the best-suited thread tension for its purpose. The sewing machine for jeans and heavy-weight materials (G type) produces well-tensed seams by the optimization of the feed mechanism. Furthermore, the G type machine comes with the new thread trimmer mechanism which promises increased reliability.
