TH-N737B 7 Pincers Hydraulic Automatic Toe Lasting Machine

The TH-N737B is a high-performance, fully hydraulic automatic toe lasting machine engineered for modern footwear manufacturers producing mid- to high-end shoes with intricate toe cap designs—such as athletic footwear, dress shoes, and fashion women’s styles. Combining robust mechanical structure with intelligent motion control, this machine delivers exceptional repeatability, operator-friendly setup, and flexible tooling adaptation to meet diverse last geometries and upper materials.
Unlike standard 5-pincer models, the TH-N737B features seven independently actuated pincers, including a yaw-adjustable center pincer (±15°) and a rotatable fifth pincer, enabling precise conformity around challenging toe shapes without manual intervention or retooling downtime.

Key Technical Advantages

±0.1 mm Repeatability via Digital Position Feedback
The newly redesigned last support mechanism features externally accessible, digitally indicated stop points for both lift height and drafting position. This allows rapid changeovers between shoe models while maintaining micron-level consistency—critical for minimizing upper distortion and ensuring uniform lasting quality across batches.

7-Pincer System with Adaptive Geometry Control
Center Pincer: Yaw-adjustable up to 15° left/right to match asymmetric or curved toe caps.
Fifth Pincer: Equipped with inward rotation function; angle adjustable per model requirements to wrap the upper tightly around the medial side of the last.
This dual-axis adaptability significantly reduces manual correction and improves fit on lasts with high toe spring or narrow profiles.

Modular Auxiliary Integration
Optional add-ons include an auxiliary binder unit (for pre-tensioning uppers) and a wiper body (to smooth wrinkles during lasting), enhancing process stability for stretchable synthetics, mesh, or delicate leathers.

Ergonomic & Intuitive Operation
All mode selections and functional controls are centralized on a clearly labeled panel. An integrated alignment laser guide projects a reference line onto the upper, enabling operators to quickly center the toe cap before cycle initiation—reducing misalignment errors and training time.

Fully Hydraulic Drive System
Powered by a 3HP main motor and 1kW heating unit (for optional heated sole units), the closed-loop hydraulic system ensures smooth, vibration-free operation at 50 kg/cm² working pressure. The robust frame minimizes deflection under load, supporting consistent performance even during extended 8-hour shifts.

Performance & Specifications

Ideal For:
Factories producing athletic, casual, or formal shoes with complex toe contours
