Semi-dry-head, 2-needle, Lockstitch Machine
The 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.
Adoption of the direct-drive mechanism enhances energy conservation and workability, and increases the needle's material penetrating force.
A semi-dry head is now installed in all of the models of the LH-3500A Series (Exclusive to JUKI)
All models of the LH-3500A Series are provided with a semi-dry head to eliminate staining with oil from the frame (the needle bar part).
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 the changeover of the feed method between the "needle feed" and "bottom feed" and changeover of the feed timing (re-placement of the timing belt).
Changeover between the needle feed and bottom feed.
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 lower thread tension.
Many different models are prepared according to the type of materials.
From a wide variety of models, the best-suited model can be chosen according to your sewing items, ranging from light- to heavy-weight materials.
The operation panels CP-18A and CP-180A are provided with a production support function.
The production support function actually consists of three different functions (six different modes), which are the output control function, operation measuring function, and bobbin counter function. Each with its own production support effect. An appropriate function (mode) can be selected as required. The parameter setting can be done on the panel located on the top of the sewing machine, thereby helping reduce operator fatigue during setup changing.
