E7/4 Combers – Top Rollers

The E7/4 Comber is a high-performance machine used in the combing process to remove short fibers, neps, and impurities, producing high-quality yarn. Top rollers in the E7/4 comber are critical components in the drafting and fiber transfer sections, ensuring smooth movement of fibers, consistent drafting, and precise control over lap feeding.

1. Grip & Guide Fibers – Work with bottom rollers to hold the fibers securely during drafting.

2. Ensure Drafting Accuracy – Maintain correct tension and sliver uniformity.

3. Prevent Slippage – Surface finish and pressure settings help maintain proper grip.

4. Reduce Fiber Damage – Smooth, polished surfaces minimize friction and abrasion.

• High-Grade Steel or Stainless Steel Shell for strength and longevity.

• Precision Polished Surface for uniform contact.

• Accurate Bearing Housing to ensure concentric rotation.

• Corrosion-Resistant Coating (where applicable).

• Balanced Construction to avoid vibration at high speeds.

DO/2S Draw Frames

The DO/2S Draw Frame is a high-performance fiber preparation machine used in the spinning process to improve sliver quality before it proceeds to the next stage. It drafts multiple slivers into one, equalizes fiber distribution, and enhances uniformity in terms of weight and fiber alignment. The DO/2S model is a well-established draw frame type, known for its reliable performance and robust design.

• Drafting: Combines several slivers into one while drafting them to improve evenness.

• Parallelization: Aligns fibers for better yarn strength and consistency.

• Blending: Mixes fibers from different slivers to improve homogeneity.

• Cleaning: Removes small impurities and fly waste during drafting.

• Top Rollers: Apply uniform pressure and guide fibers through drafting zones.

• Bottom Rollers: Drive the fiber slivers at controlled speeds.

• Drafting System: Usually 3-over-3 or 4-over-4 roller arrangement for precision drafting.

• Clearer Rollers: Remove lint, dust, and short fibers from roller surfaces.

• Sliver Can Delivery System: Neatly coils the finished sliver into cans for transport to the next process.

• Drive System: Gear-driven or belt-driven for consistent speed control.
