JUKI LH-3578A 65MM CURTAIN TAPE MACHINE HEAD ONLY

Adoption of the direct-drive mechanism enhances energy conservation and workability, and increases the needle's material penetrating force

Energy-Saving - Reduced by 21%
Adoption of a compact motor for the direct-drive machanism and the newly developed control box (SC-920A*) decrease power consumption by approximateley 21%.

Operability
Adoption of the direct-drive machanism improves stop accuracy and responsiveness, leading to increased working efficiency.

Material penetration force - Increased by 32%
Adoption of a high-torque type 500w motor promises added material penetration force when the sewing machine sews multi-layered parts of heavy-weight material.

A semi-dry head is now installed in all of the models of the LH-3500A Series

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 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 a 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.

Production support function

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.

The best-suited thread tension is achieved according to the sewing specifications

Two different types of thread tension controllers have been developed
The needle tension controller comes in two different mechanisms according to the type of sewing machine. For the A and F types, seam quality free from puckering and irregular stitches is promised. For the S and G types, the sewing range has been broadened to produce well-tensed seams even when thick thread is used.

Wire type and round-hole type needle bar thread guide
Two different kinds of needle bar thread guides (needle clamps), the wire type and round-hole type, have been developed according to the type of sewing machine. The wire-type needle bar thread guide has been adopted for the A and F types which require the sewing capability to sew light-weight materials and foundations without puckering or irregular stitches. The round-hole type needle bar thread guide has been adopted for the S and G types which sew materials requiring well-tensed seams. In addition, the G type is provided as standard with the presser foot with guide which is effective for the topstitching process.

Material-friendly micro-lifter mechanism

The presser foot can be lifted by a minute amount by adjusting the eccentric pin located in the presser lifter lever section.
When sewing shaggy and elastic fabrics, the load applied to the material is reduced by slightly lifting the presser foot. Materials are handled more easily and are finished without sacrificing the inherent texture of the material.

Two selectable new-method oiling mechanisms

1. ECO-oli method (circulation type)
The oil dropped from the hook and its surrounding sections into the under-cover is filtered to remove dirt and dust and is then returned to the oil tank. This method saves the effort of oiling and reduces oil consumption.

1. Clean oil method
The oil dropped from the hook and its surrounding sections into the under-cover is not returned to the oil tank, but only clean oil is supplied to the hook at all times.

* The oiling method can be changed over as desired.
