Major drive mechanism is electronically controlled

 

An electronic control feature has been adopted for the material feed mechanism, needle rocking mechanism, needle thread trimming mechanism, bobbin thread trimming mechanism, cloth cutting knife mechanism and presser bar lifting mechanism. In addition, mechanisms such as V-belts, stop-motion mechanisms and cams have been substantially reduced to ensure operation with lower vibration and noise.

Multi-functional operating pane

 

All kinds of data can be entered on or selected from the operation panel. Various data, such as pattern numbers and stitch shapes are indicated on the LCD section with easy-to-understand pictographs. Parameters can be modified through the control panel.

 
 
 
 

Multiple knife dropping function

 

 

Thanks to the multiple knife-dropping function, it is no longer required that the knife be changed at the time the buttonhole size is changed. The number of knife dropping times can be automatically set according to the buttonholing size in cases where the buttonhole size is frequently changed for small-lot productions or during the cycle sewing of buttonholes that are different in size.

 

Cycle sewing and continuous sewing.

 

 

Twenty different programs can be registered, and as many as 15 different patterns can be stored in one cycle. The machine is able to continuously sew two or more different patterns without requiring the work clamp foot tube lifted. As many as 20 programs can be registered, and six different patterns can be stored in one program.

 

 
 
 
 
 
 

Electronic thread tension control system

 

Needle thread tension for sewing parallel and bartacking sections of buttonholes can be separately controlled through the operation panel and stored in memory according to various sewing conditions (e.g., type of thread, type of material and sewing speed).Thread tension for basting stitching can be specified separately.

 
 
 

Basting stitch mechanism is effective

 
 
 
 
 

Easy threading

 

The needle bar can be shifted to the rightmost end position with the work clamp foot lowered. This facilitates threading of machine head.
