Sanforizing Rubber Belts
Endless natural rubber belts for the compression unit of sanforizing machines.
They run 50–72mm thick with hardness 40±2 and work against heating rolls up to about 130°C.
Every belt is made to your machine size.

Common applications
Where sanforizing rubber belts work
01
Sanforizing units
Natural rubber shrinking belts for the compression unit of compressive-shrinking machines.
02
The felt calender
The calender that follows the rubber unit runs a needled felt blanket in polyester or Nomex.
03
Regrinding and replacement
Grind the belt every 500,000 to 1,000,000 metres of fabric. At high load a belt lasts about 6 months.
