LF-1660 Pressure Finger

Flyer presser for LF-1660 speed-frame configurations.

Product details

LF-1660 pressure finger

Lightweight, high-strength alloy body to minimize roving breakage and uneven bobbin builds.

Product: Flyer pressure finger
Model: LF-1660
Machine make / frame type: LMW Speed Frame (Zinser 660 design)
Package size / mounting: 16" × 6" / 16" × 7" standard

Technical characteristics

Material: High-grade alloy steel, forged mild steel, or lightweight aluminum alloy.
Surface Coating & Finish: Hard Chrome Plating / Nickel Plating: Minimizes roving friction and prevents surface wear. Black Oxide / Powder Coating: Provides corrosion resistance and extended operational life.
Dynamic Balancing: Individually balanced to operate at speeds up to 1200–1500 RPM without flyer vibration.
Primary Function: Maintains steady, uniform pressing tension on the roving as it winds onto the bobbin, ensuring high package density and clean unwinding at the ring frame.

The LF-1660's details carry an unusually useful line — machine make: LMW Speed Frame, Zinser 660 design — and a fitment spanning both standard package sizes, 16" × 6" and 16" × 7". One finger pattern covering both builds is a genuine stores advantage on mixed LF-1660 frames. The model's other signature is weight: a lightweight, high-strength alloy body, chosen — as this page states — to minimise roving breakage and uneven bobbin builds, because every gram carried on the flyer is a gram the drive must accelerate and the finger must control at 1,200–1,500 RPM. Finishes follow the range standard: hard chrome or nickel plating at the roving contact, black oxide or powder coating against corrosion.

Pressure Finger — Lf-1660 — Frequently Asked Questions

What is a pressure finger?

This flyer presser guides roving onto the bobbin. Match the flyer reference, presser dimensions, bobbin size and machine configuration when ordering a replacement.

Which machine does the LF-1660 pressure finger fit?

It is made to the original LF-1660 dimensions for a direct replacement fit.

When should a pressure finger be replaced?

Replace a pressure finger if its yarn-contact surface is badly scored, the arm is cracked or deformed, the mounting is loose, or uneven bobbin build persists after the setting has been checked. Inspect the stopped machine and match the replacement to the existing flyer and presser reference.

Do you supply in bulk and export?

Yes. We supply mill-quantity lots and export to 87 countries.

Does one LF-1660 Pressure Finger really serve both 16x6 and 16x7 packages?

Yes — the model details list both 16" × 6" and 16" × 7" as standard fitments for this pattern, unlike the Electro-Jet sizes, which are package-specific. Still confirm the flyer profile on your frames when ordering, because arm geometry varies between installations of the same frame model.

Why is the LF-1660 made in a lightweight alloy?

Because the finger rotates with the flyer: a lighter finger reduces the load the drive carries and responds more cleanly at speed, which the product details link to fewer roving breaks and more even bobbin builds. The alloy used is high-strength, so the weight saving does not come at the cost of stiffness at the pressing face.
