The AS 2.1 A is an automatic tying machine equipped with pulling belts group for sausages.

The two belts are positioned to avoid damages to the product, which will lay on the inferior one; then the superior will be manually adjusted based on caliber. Machine’s cleaning operations and eventual parts replacements are practical and rapid: the machine has been projected in order to disassemble the pulling belts without using keys.
