Pu Sole Roughening Machine

PR 1145

The PU Sole Roughening Machine is used to roughen PU soles before bonding, helping improve adhesive grip, sole attachment and product durability.

• It is designed for roughening PU soles before the bonding process.
• It removes the smooth outer surface layer of the sole.
• It creates a controlled rough texture for better adhesive penetration.
• VFD speed control allows adjustment for different sole materials.
• It improves bonding strength and helps reduce rejection rates.
• Its robust build and ergonomic design support high-production footwear manufacturing.

Achieving strong sole-to-upper adhesion requires proper surface preparation. PU soles often have smooth moulded surfaces that can limit adhesive performance if not treated correctly. The PU Sole Roughening Machine is specifically designed to create a controlled roughened surface that enhances adhesive bonding and improves overall footwear durability.

The machine utilizes precision roughing wheels and a variable-frequency drive (VFD) system that enables operators to optimize processing speeds for different sole materials and profiles. By providing consistent surface preparation and reducing manual variability, this helps manufacturers achieve higher bonding quality and more reliable production outcomes.
