Thanks to the needle-feed mechanism which offers excellent efficiency of feed, the machine ensures accurate stitch pitches (stitch length) as well as preventing slippage of the upper cloth. The bottom feed’s locus has been improved to match the needle feed motion, thus the machine produces beautiful seams without stitch gathering, even when it is used for sewing slippery and difficult-to-feed material or for handling a difficult process. The needle feed mechanism is a so-called “dry type”, which does not require oiling. With this mechanism, a highly reliable machine structure, free from oil leakage troubles, has been achieved. The frame, which requires only a minute quantity of lubricating oil, is structured to eliminate oil leakage.
The machine has been configured to eliminate the oil pan, and supplies a minute quantity of lubricating oil to the hook and needle bar, thereby contributing to the creation of a clean work environment. The machine saves you the time and trouble of removing the knee-lifter and cover. This means that the machine head can be tilted for cleaning and maintenance without the inconvenience of removing the knee-lifter and cover.
The DLN-9010A is installed with the latest compact servomotor which has also been adopted in the DDL-9000B in the direct-drive system, in which the servomotor is directly connected to the main shaft.
Precise control of the thread trimming timing is now enabled. As a result, the thread trimming speed is increased 1.5 times or more while maintaining the high reliability of the conventional type of thread trimmer.
