What Is The Founction of The Spindle in Braiding Machine?

In a braiding machine, the spindle is a critical component that plays a central role in the braiding process. Its primary function is to carry and control the yarn or thread as it interlaces to form the braided structure. Here’s a detailed breakdown of its functions:

Key Functions of the Spindle in a Braiding Machine:

1. Yarn Holding & Tension Control

• Each spindle holds a bobbin or spool of yarn, ensuring a continuous supply during braiding.

• It maintains consistent tension on the yarn to prevent slack or breakage, which is crucial for uniform braid quality.

2. Orbital Motion for Interlacing

• Spindles are mounted on a horn gear or track system that moves them in a circular or figure-8 pattern.

• This motion allows the yarns from different spindles to cross and interlace around the core (if present), forming the braid.

3. Directional Guidance

• The spindle guides the yarn along a precise path to ensure proper twisting and intertwining with other yarns.

• It prevents tangling and ensures the correct braid pattern (e.g., diamond, regular, or Hercules braid).

4. Speed Synchronization

• Spindles rotate at synchronized speeds to maintain the braid’s symmetry and density.

• Modern machines may adjust spindle speed dynamically for complex braids.

5. Core Braiding (if applicable)

• In machines designed for hollow or core-filled braids (e.g., cables, ropes), spindles alternate around a central core, embedding it within the braid.

Types of Spindles:

• Passive Spindles: Rely on machine movement for yarn delivery (common in traditional braiders).

• Motorized Spindles: Independently controlled for advanced braiding (e.g., 3D braiding machines).

Why Spindles Matter:

• Precision: Their movement dictates the braid’s tightness, pattern, and strength.

• Efficiency: Proper spindle design reduces yarn waste and machine downtime.

• Versatility: Adjusting spindle count (e.g., 8, 16, 32) allows different braid complexities.

Without properly functioning spindles, the machine would fail to interlace yarns correctly, leading to defects like loose strands or uneven braids.
