LH-3578A-7 (with automatic thread trimmer)
LH-3578A
Semi-dry head, 2-needle Lockstitch Machine
Description
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 sewing machine has been designed to eliminate waste time and the operator's stress. |
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. |

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 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 round-hole type needle bar thread guide has been adopted for the 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. |
Our direct-acting thread trimmer mechanism, which spreads thread without fail, has been further improved. The thread trimmer trims the needle thread and bobbin thread without fail even when thick thread is used. In addition, the thread trimmer's bobbin thread retaining force has been increased. |
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. |
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. 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. |
