Electronic Stop and Start Motion
The electronic start and stop motion extends machine life and improves machine reliability by eliminating the stop motion and clutch mechanisms.
Patented Mechanisms
The S-4000 contains six patented mechanisms:
- Needle Bar Drive
- Looper Drive
- Main Cam
- Double Lobe Cam
- Bite Mechanisms
- Feed Mechanisms

Revolutionary Design
The S-4000 machines has reduced the number of parts compared with the previous S-2 model.

Fully Enclosed Mechanism
DC Drive Motor is fully enclosed within the head casting, eliminating the need for an under the table mounted clutch motor, pulley, belt and brake. This reduces required maintenance and eliminates oil and dust around the working area.
Control Panel
Two versions of the control panel are available, either a simple key-pad control panel (IDEC) or a touch screen display (Easy View) using easily understood symbols and graphics.
 IDEC control panel  Easy View control panel Decorative No-Cut Buttonhole
The S-4000 ISBH produces a buttonhole which has a similar appearance to a normal buttonhole but is purely decorative and non-functional. This type of buttonhole is not cut and is used on the sleeves of men’s and ladies’ jackets, suits and sports coats. Since this buttonhole is not cut, and is done on a fast chainstitch machine, sewing at speeds up to 3,800 spm, the operator is able to sew 2 – 3 times more jacket/coat sleeves, than with a conventional buttonhole machine.
Only one square bar is sewn while at the other end the small stitch gives the appearance of a rounded end. On the finished garment the button is sewn over the square bar. The size of the buttonhole is from 15,8 mm to 25 mm (5/8” to 1”). To see the difference between the regular and ISBH buttonhole please see the drawings below.

Productivity & Flexibility
Chainstitch buttonholing provides increased productivity with no bobbin change. The elasticity of the chainstitch also provides the flexibility needed for many fabrics such as knitwear.
Pneumatic Clamping, Cutting and Thread Trimming
- Pneumatic cutting reduces the number of adjustments and increases the consistency and reliability of the cut.
- Pneumatic clamping reacts to different thicknesses and types of fabric.
- Pneumatic thread trimming gives consistent and reliable trimming at the end of each sewing cycle.
Semi-Automatic Lubrication System and Oil Monitor
The S-4000 series is equipped with the drip oil wick lubrication system and oil level monitor. This system prolongs the machine life and reliability.
High Speed Sewing with Reduced Noise Level
The S-4000 series has electronically adjustable sewing speed up to 3,800 spm and are the fastest chainstitch buttonhole and special application machines available. Due to the DC Drive Motor the machine is 20% faster than other models. The noise level is also significantly lower on the S-4000.
