The frame has reasonable and stable structure, and is easy to adjust vertically and horizontally,simple and decent.

The technology of drafting to feed by elevated trolley is applied in conjunction with optical auto-stop for breakage prevention to make the feed quality stable and reliable. Unexpected draft is minimized meanwhile to prevent re-feeding of fiber.

Dual roller groove rotary holding.Upper roller reduces Vibration,increases pressure for stable driving. Minor draft ratio helps fberextension. Lower roller has anti winding device.Manual switch at draft-to -feed unit for manual feeding or clearing congested wool tops.

The unique large fber input mechanism is particularly TONGDA Application Showcase Main technical parameters Spinneret (spindle) per machime suitable for spinning thick or extraordinary thick yarn,which increases the yarn yield up to a level which is much beyond the capacity of the other models of machine.

The twisting dust cage, made of quality materials with an anti-static coating,is light, hard, breathable and rotates flexibly.This boosts twisting effciency,ensuring stable and strong yarn. Supported by double bearing seats, it suits high-speed rotation and has a longer service life.

Negative pressure sources, channels, and ports are well-allocated to ensure even negative pressure effciently. The port negative pressure difference is ≤5%,Exhaust removes and collects dust at each spinneret for collective discharge.A gettering box can be set up according to fber types.

Independent output device enables adjustment ofwinding force randomly.winding force randomly. Winding groove drum has two options of bake lite and alloy.
