AC-172N-1790
High-speed, Computer-controlled Buttonholing Indexer
Applicability to vertical stripe patterns has been improved. The newly-develpoed sub-clamp mechanism prevents slippage of the material to enable accurate and consistent buttonholing.
The AC-172N-1790 is a high-speed, computer-controlled buttonholing indexer which achieves higher productivity and consistent buttonholing of top-center plaits.

Product overview
The AC-172N-1790 is the newly-developed next-generation buttonholing indexer, which comes with the highly evaluated high-speed machine head LBH-1790 and is provided as standard with the preset mechanism to increase productivity. In addition, called sub-clamp mechanism helps achieve both accurate and consistent buttonholing quality.
High-performance indexer mechanism
A stepping motor controls material feed amounts in increments of 0.1 mm to feed materials with both consistency and accuracy. The machine is able to sew 1 to 20 buttonholes and stores 20 different stitching patterns in its memory.
The sewing machine is provided as standard with a facility that moves the carriage unit synchronously with the operation of the sewing machine during sewing, thereby enabling accurate and unfailing feed of the material while preventing material slack.

Sub-clamp device which enhances applicability of the sewing machine to vertical-strip patterns.
The sewing machine comes with a newly-developed mechanism which prevents slippage of the material at the time of its delivery from the preset board to the sewing machine. This helps increase applicability of the sewing machine to buttonhole vertical-striped garments.
The independent sub-clamp mechanism of the carriage unit on the sewing machine head securely clamp the material upon delivery of the material from the preset board to the sewing machine, thereby preventing the material from slipping out of position. As a result, the sewing machine is allowed to achieve accurate buttonholing of top-center plaits with consistency.

Knee Switch
This switch is operated with the knee to actuate the sewing machine (sub-clamp device).
The knee switch can be turned on by the operator with his/her knee while he/she still holds a garment body on the sewing machine with both hands. As a result, the operator is able to place the material securely on the sewing machine to reduce the time required for accurate positioning of the material. Needless to say, a hand switch is also provided.
In addition, if the operator turns on the switch after having placed the material on the sewing machine, the sub-clamp device will automatically bring the subsequent material to the sewing position after the completion of buttonholing of the current material to allow the sewing machine to immediately start the next buttonholing. This function works effectively, especially in cases where the operator is operating two or more sewing machines or is carrying out other work simultaneously.
