The Juki LH-4128 achieves the world’s highest sewing speed of 4,000sti/min as a semi-dry head machine, contributing to increased productivity. Simple adjustments of the machine and replacement of gauges have been enabled, saving time and effort in maintenance. In addition, it is possible to change over the feed between the needle feed and bottom feed.

The Juki LH-4128 machines come with a direct-drive, semi-dry head, and high & long arm to provide maintainability, silent operation and beautifully-finished seams. This is the highest grade 2-needle lockstitch machine series launched by JUKI.

Range of sewing capabilities is dramatically increased
The Juki LH-4128 has been designed laying importance on the ease of thread tension adjustment in cases of the changing of sewing materials ranging from light-weight (soft) to heavyweight (hard). All thread paths on which the needle thread and/or bobbin thread passes have been totally rechecked to ensure a range of sewing capabilities that is substantially broader than that of the conventional models.

Changeover between the needle feed and bottom feed (LH-4128)
For example, for processes such as the topstitching of brassier cups and top-center plait of men’s shirts, which need to be sewn so as to prevent puckering, the use of a bottom feed gauge is recommended. The bottom feed gauge is effective at the prevention of puckering and enables sewing with a lower tension applied to the thread.

Soft opener which helps reduce operating noise of the machine
The opener achieves a silent operating environment which has never been obtained by the conventional ones. It guides the bobbin case with literally a “soft touch” to reduce bobbin thread tension, thereby helping tense the thread uniformly and produce beautifully finished seams.

Sewing environment which ensures excellent workability
The Juki LH-4128 is provided with a high & long arm which facilitates the handling of sewing products even when sewing large ones such as jeans. In addition, increased stop accuracy and excellent responsiveness, which are the most prominent features of the direct drive, work in combination with the high & long arm to help eliminate operator stress, thereby increasing productivity.
