Common options include V-grooves and U-grooves, or multiple grooves of different sizes on the surface.

Types of Haul-Off Belt Slotting
Longitudinal Grooves (Lengthwise)
- Purpose: These are the most common slots, designed to “nest” the pipe or cable.
- Function: They increase the contact surface area for round profiles, preventing the product from sliding sideways or rotating during the pull.
- Shapes: Available in V-Grooves, U-Grooves, or Rectangular profiles Grooves depending on the diameter of the extrusion.
2. Lateral / Transverse Slots (Crosswise)
- Purpose: Slots cut across the width of the belt.
- Function: * Flexibility: They allow thick, hard-coated belts to wrap more easily around small-diameter pulleys without cracking.
3. Multi-Directional / Custom Slotting
- Purpose: Diamond, grid, or herringbone patterns.
- Function: Used for specialized profiles where multidirectional grip is required to prevent “snaking” at high speeds.
Expert Insight for Yonghang Customers
FAQs:
- Residue Management: If you is extruding wet pipes, recommend Lateral Grooving combined with a Water-Resistant Rubber to prevent hydroplaning between the belt and the pipe.
- CNC Precision: Yonghang uses CNC grinding/milling for slotting. Unlike manual cutting, CNC ensures that every slot is identical, which is critical for the synchronized “caterpillar” movement.
- The “V” Advantage: For customers running multiple pipe sizes on one line, a V-groove is more versatile than a U-groove, as it can center various diameters effectively.
