  • The third drying stage provides to pass the woven fabric coming out from the second dyeing stage into a machine, known as a Rameuse machine i.e. stenter, which has the purpose of making the woven fabric reach the desired height, ready to face the next passage.
  • The fourth finishing stage calls for subjecting the woven fabric with artificial and natural fibres coming out from the third drying stage to operations of pressing, resining and scenting.
  • The pressing operation of the fourth finishing stage provides that pass the woven fabric with artificial and natural fibres coming out from the third drying stage into a machine known as a calender.
  • The pressing operation of the fourth finishing stage is repeated for a number of cycles comprised between 1 and 3.
