The chainstitch lingerie tacker machine for finishing operations of flatseams and flatlock seams. The chainstitch lingerie tacker machine is the only machine available on the market that uses new method of chain cutting and simultaneous sewing of the seam finish. It simply vacuums and trims the chain and sews over the flatlock seam so it is secured. The result is a flatseam that is elastic yet strong and aesthetic. The main application of the chainstitch lingerie tacker machine is on all kinds of underwear and fine knitted garments. The chainstitch lingerie tacker machine is supplied with a specially designed angle –adjustable table for operators’ comfort.


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

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.

Microprocessor Control

The microprocessor control ensures maximized ramp-up and ramp-down speeds to achieve minimized cycle times.

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.

Angle Adjustable Work Table

The S-4000 LT machine is available with specially designed angle –adjustable table for operators’ comfort. The angle can be set to 5 degrees.


The machine is designed for finishing operations on all kinds of underwear.
