The machine can be used for the hemming process of the sleeves and bottoms of T-shirts and for the covering process for sportswear and knitwear. It is a basic one which can be used for a broader range of processes independently. The sewing machine supports hemming and covering (single-side bent and flattening) by the use of the guide supplied with the unit. |
This model is best sui ted to the covering processes for polo shirts, sportswear and knit outers, etc. The sewing machine has been provided as standard with an exclusive gauge (throat plate, feed dog) and guide for flattening. The sewing machine is also supplied with a guide for covering (folding over overlock seams) and a hemming guide (excluding the throat plate) as accessories. |

The sewing machine has adopted the timing-belt drive method to achieve sewing without any loss of driving force. Belt abrasion powder which can stain the product is no longer produced. Setup of the conventional belt is troublesome, but now easier setup of the belt is also achieved by the adoption of the timing belt. In addition, the motor size has been reduced to achieve energy-saving. |
The new model control box SC-921A has been newly developed. The control box is resistant to voltage fluctuations, noise and vibration. The new model control box is provided with an energy-saving mode for the first time in a control box for sewing machines. It reduces power consumption during standby time when the motor is not rotating. The new model operation panel, CP-18B has been adopted. The CP-18B is installed with a product support function.

Elastic material or delicate material can be sewn with the presser foot kept slightly raised. This effectively helps reduce the degree of slippage, warpage and damage of the material. |
Stitch pitch (stitch length) can be adjusted with ease simply by turning the stitch dial. |
It is possible to finely adjust the differential feed amount to a best-suited value for the material to be used. In addition, the differential feed ratio remains the same even when the stitch length is changed. |
The bed seat has been provided as standard with the auxiliary cover. By using this cover, the sewing machine is not only applicable to the sewing of tubular products, but also to a broad range of processes, as in the case of the sewing machines with a flat bed. In addition, the top-loading binder can be installed with ease. |
