Stringer Belts, 2-layers PTFE belts for tabber stringer machine
Stringer Belts are laminated with 2 layers of PTFE coated fiberglass fabric, which is continuous running straightly, has higher dimensional stability, longer lifetime and better performance than normal PTFE belt.
This belt is designed for tabber and stringer machine, which can withstand high working temperature, has easy release surface, and the holes can be customized punched in order for a constant vacuum.
Advantages of Stringer Belts
★ Dimensional stability
Stringer belt will continuous working in tabber and stringer machines 24 hours, and it is used to soldering strings by 12 ribbons on tested cells.
In this case, the dimensional stability of stringer belts will be very important, it will affect the straightness of the welding ribbon after processing.
★ Continuous running straightly
In order to enable precise overlay of main bus bar and welding ribbon, the stringer belt is requested to running straightly continuously.
★ Heat resistant and non stick
PTFE coated fiberglass fabric can continuous working under 260°C (500°F).
The perfect non stick surface will make cell easily release from the belt.
★ Anti-static surface
Stringer belts are laminated with one normal PTFE fabric and one black anti-static PTFE fabric, which will protect cell from static during processing.
★ Customized punched holes for constant vacuum
PTFE stringer belt can be punched into 2 holes / 4 holes / 8 holes & etc per line, the hole size and position can be customized.
