SDG-4AS Interlock Open Width knitting machine can cut the fabrics immediately after knitting and roll it as a full width to avoid the center line.
This device is a must need when making elastic fabrics, especially Polyester/Nylon with Spandex.
Sun Da Open width take down system equip the most updated technology ensure the rolling fabrics at even GSM from both side to center.
It reduces the weaving effect / uneven effect after dyeing and finishing.
---
We persist that only the strong foundation can absorb the vibration during the machine running
The open width steady base frame gives a stable platform for sensitive fabrics to produce.
From the machine structure design and manufacture, we are striving to build up more and more quality machines.

The SDG- 4AS machine permits various kinds of structures be able to knit: Punto di Roma, Swiss & French Pique, Spacer/ Scuba, vertical stripe, and etc by simply arranging cam system 2:2/ 2:4/ 4:4/ 4:6.

SD-4AS YOUR BEST CHOICE OF SENSITIVE ELASTIC FABRICS.

■ OPEN WIDTH / SLITTING TAKE DOWN SYSTEM:
Sun Da open width system equip the most updated slitting and rolling technology to assure the spandex fabrics evenly roll.

■ STEADY FRAME FOUNDATION:
We concern that manufacturing a good quality machine is the same as building up a house.
Needless to say the foundation is how important to a house in terms of the machine to its frame structure.

■ DIAL INDICATOR:
When adjusting the fabrics GSM or the needle timing, dial indicator device can easily help the technician to measure the cylinder position and make the adjusting work more efficiency.
Cylinder height adjustment and Cylinder horizontal adjustment can take record on the fabrics work sheet and ease the adjustment work on the next machine. 

■ ZIRCONIA YARN GUIDE:
Adopt Zirconia yarn guide, smooth the yarn feeding and reduce the static while knitting.
It significantly reduces the needle breakage and extend needle life time.

■ PRECISION PARTS AND PROCESSING:
With our in-house precise processing CNC machine and high standard heat treatment on the main parts such as gear/ cams… , gives machine a stable, durable, and high performance features.
