Main Head Stock: includes the gear reduction unit that drives the draft system, the main motor, the fiber waste collection system, the ring rail drive, the electrical equipment. The fiber waste collecting system consists of an air suction system fan and of a manual cleaning filtering element. The ring rail drive consist of an independent motor driven by a frequency converter and electronically synchronized to the drafting bottom rollers.

Movement of the ring rail, balloon control rings and lappet bar is controlled by a individual 2.2KW servo motor, which is electronically synchronized with the movement of the draft rollers All the adjustments of the ring rail movement for the cop build up are carried out via keyboard (stretch, increment, cone height, bottom, etc.), even when the machine is running. System includes a device for the controlled stop of the spinning frame in case of electric power failure.


Spindle motor is a three phase, 37kw induction motor driven by a frequency converter. This system driven by a single central driving shaft, drives 48 spindles simultaneously (24 per side). This driving system is fully covered by casing, which saves cleaning over time and ensures greater safety to the operator.
