The LBH-1796AN is a subclass model of the LBH-1790AN Series. This product is provided with a 220mm work clamp foot. It follows the world's highest sewing speed, deeply recessed shape of the machine head and dry-head mechanism of the existing LBH-1790AN. In addition, the LBH-1796AN can also be used as a simplified indexer to sew three buttonholes in a row. |
When the optionally-available indexer mechanism is installed on the LBH-1796AN, the operator can attend to two units of this model of sewing machine at one time or can use the LK-1903BN button sewing machine together with the LBH-1796AN, thereby not only further increasing productivity, but also ensuring consistent product quality due to the production capability without requiring the operator to have any special skills. |
Management, browsing and editing of data can be carried out on the application software Data on sewing machine adjustments made according to the product to be sewn can be transferred to a commercially-available Android tablet in contactless mode. This enables quick check for uniform settings as well as confirmation of conditions of sewing machines in a sewing line, thereby facilitating setup changes. The operation panel is also provided as standard with a USB port. Data management and software update can be carried out with ease using a USB thumb drive. Data items of sewing can be numerically managed to ensure "stable quality" and "reduction in time required for setup changes". Quantified sewing data can be externally taken from the sewing machine using an Android tablet or USB thumb drive. *Android OS Version 6.0 is recommended to use JUKI Smart APP. (Operation is confirmed with respect to Versions 5.0 and later.) Contact JUKI distributor in your area for how to use the application software. |

The maximum sewing speed is 4,200 sti/min., and the jump speed is 200 mm/s. The cycle time has been further reduced for continuous sewing. |
Cycle sewing Twenty different programs can be registered, and as many as 30 different patterns can be stored in one program. Continuous sewing The machine is able to continuously sew two or more different patterns without requiring the work clamp foot to be lifted. As may as 20 programs can be registered, and six different patterns can be stored in one program. (Related parts need to be exchanged for optional ones.) |

The basting stitch is effective on elastic materials such as knits. Basting stitch: Since the needle thread is tucked in without fail, it will never jut out of the buttonhole seams. Basting stitch can be sewn by nine rounds. |

It is able to store 99 different patterns in its memory, which can be selected as desired from the operation panel. |

*1 This is an optional guage that prevents cloth displacement that can oocur at a stepped part. A presser to be used is B1552781000A/B1552782000.
*2 The width of the convex part of the needle plate is wider than any convex part of needle plates with other specifications. If this is used with a feed plate with other specifications together, the feed plate may interfere with this.

Caution | Figure | |||||
When replacing the throar plate between LBH-1790A* and LBH-1790A*B, changing the machine type setting in the memory is required since the distance between the needle entry and knife different than the standard type. [Size of needle entry knife groove] LBH-1790A*B, LBH-1796A*: 1mm LBH1790A*, LBH-1795A*, LBH-1790S: 2mm |
||||||
LBH-1790S, 1796A and 1796AN use the special frame, which if not compatible with LBH-1790S, 1790A, 1790AN, 1790AB, 1790ANB, 1795A and 1795AN. therefore, the presser type 1 to 3 cannot be assembled. | - | |||||
There is a difference of timing gage in LBH-1790S, 1790A and 1790AN; LBH-1790AB and 1790AMB. Since the thickness of the throat plate is different, the length of the timing gage differs. The hook timing does not change since the total length is the same. |
- | |||||
When the feed width is more than 5mm with LBH-1790S, 1790A, the presser arm and oil shield need to be replaced. (For details, refer to the parts book, specia specifications 2.) |
- | |||||
When the feed direction is more than 41mm with LBH-1790S, 1790A, the presser arm needs to be replaced. (For details, refer to the parts book, special specifications 2.) |
