LF-4280 Pressure Finger

Flyer presser for LF-4280 speed-frame configurations.

Product details

LF-4280 pressure finger

Precision-balanced to eliminate vibration during high-speed flyer operation. Built for speed-frame flyer assemblies.

Product: Flyer pressure finger
Model: LF-4280
Machine make / frame type: LMW / Zinser new-generation frames
Package size / mounting: Modern high-speed geometry

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.

LF-4280 is the new-generation entry in this range: this page assigns it to LMW / Zinser new-generation frames and describes its mounting simply as modern high-speed geometry — which is an ordering warning in disguise. New-generation flyer arms do not accept the older patterns, and the LF-4280 does not substitute for the LF-1660 or the Holz-type fingers on earlier frames. Its design emphasis is balance: precision-balanced for high-speed flyer operation, within a range whose fingers are individually balanced for 1,200–1,500 RPM. On a new-generation frame running at the top of that band, a finger that is merely adequate announces itself as vibration the whole flyer assembly can feel.

Pressure Finger — Lf-4280 — 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-4280 pressure finger fit?

It is made to the original LF-4280 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.

How is the LF-4280 different from the LF-1660?

Generation and geometry. The LF-1660 follows the Zinser 660 design for LMW speed frames and covers both standard package sizes; the LF-4280 is built for LMW / Zinser new-generation frames with modern high-speed flyer geometry. The two are not interchangeable — order by frame generation and arm geometry, not by appearance.

What should I send to confirm an LF-4280 order?

The frame make and model, plus a photograph or a drawing of the finger and its mounting on the flyer arm. New-generation geometry varies between frame series, and the ordering guidance on this page asks for the exact machine model and arm geometry before the configuration is confirmed — a sample settles it completely.
