Direct-drive, high-speed, sewing system with automatic thread trimmer
Commitment to “seam quality”is poised to enter a new era with JUKI’s next-generation sewing system. The change is driven by digitalization. Until recently, sewing machines have been adjusted by human operators based on personal hunches and experience.
Now, with JUKI's digital sewing system DDL-9000C, sewing machine adjustments are fully digitalized. The settings can be reproduced with total accuracy to perfectly suit the materials being sewn.
Vertically- and horizontally-driven digital feed mechanism
Thanks to the world's first vertically-driven digital feed mechanism, the feed dog height can be adjusted with ease according to the material fabric of product to be sewn, thereby improving seam quality. Thanks to this digital feed mechanism, thread trimming is carried out with the feed dog lowered in the case the shorter-thread remaining thread trimming function is enabled.
As a result, the clearance provided between the throat plate and the material is eliminated, thereby stabilizing the length of thread remaining after thread trimming.
The feed dog does not protrude the top surface of throat plate when the sewing machine stops with its needle bar up, thereby facilitating placement/removal of the material on/from the top surface of throat plate and preventing the material from being damaged by the feed dog.
Various kinds of feed locus can be selected.
Digitalized vertically- and horizontally-driven feed mechanism allows easy adjustment of settings such as the feed locus only on the operation panel according to the material to be sewn.
