It is a modular machine with 4 spindles, which can be extended up to a maximum of 40.
The shrinking process can be made on either pre-dyed fiber yarns, or on raw color yarns to be delivered directly on soft dye packages.
A winding machine can be placed in front of the “HBI” either model “S-HBF” with manual doffing, or model “SDA-HBF” with automatic doffing to rewind the shrunk yarns onto cones.
Each spindle has its own motor and frequency inverter. This enables easy start up and handling, with the advantages of electrical/mechanical simplicity and low cost maintenance.
