Semi-dry head, 2-needle Lockstitch Machine
The Juki LH-3588A-7 (Juki LH-3500A Series), with a large hook for jeans, is provided with a “large hook” which is 1.7-fold larger than the standard hook provided for the model launched this last January. With the large hook, this machine helps reduce the frequency of bobbin thread changing when sewing jeans or the like with thick thread.
In addition, the curvature of the thread path has been minimized to improve the feed locus. This promises a strong and smooth feed of the material even when sewing heavy-weight materials for jeans.
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-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 Juki 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.
