TH-N737MA 9 Pincers Hydraulic Automatic Cementing Toe Lasting Machine

Product Description

The TH-N737MA redefines toe lasting efficiency by seamlessly integrating automatic hot melt adhesive application with 9-pincer hydraulic forming—eliminating manual brushing, reducing material waste, and ensuring uniform bond strength across every pair. Designed for high-volume producers of athletic, casual, and fashion footwear, this machine addresses one of the industry’s most persistent pain points: inconsistent glue coverage leading to delamination or reshaping defects.
Unlike conventional lasting machines that require pre-glued uppers, the TH-N737MA features a built-in precision hot melt dispensing system with a temperature-controlled glue tray. As the upper is positioned, molten adhesive is automatically applied to the toe vamp area just before lasting—ensuring optimal open time, perfect alignment, and immediate bonding under pressure.

Why Integrated Gluing Matters
Zero manual brushing: Removes variability from operator technique.
Reduced glue consumption: Targeted application minimizes overspray and waste.
 Stronger bond integrity: Adhesive is applied at peak tackiness, directly before mechanical forming.
Faster cycle time: No waiting for pre-applied glue to reach working viscosity.

Advanced 9-Pincer Forming System
With nine independently controlled pincers, the TH-N737MA offers superior contour adaptation compared to standard 5- or 7-pincer models:
Center Pincer: Yaw-adjustable ±15° to accommodate asymmetric or curved toe caps (e.g., pointed dress shoes, wide-toe sneakers).
Fifth Pincer: Features inward rotation adjustment to wrap the medial side tightly around narrow or high-spring lasts.
Additional Side Pincers: Provide enhanced support on flared or structured toe boxes, preventing wrinkles and pull-through.
All critical motion parameters—including last lift height and drafting depth—are set via externally accessible digital indicators, achieving ±0.1 mm repeatability for rapid model changeovers without recalibration.

Modular Process Enhancements
Optional add-ons further optimize surface quality and bond reliability:
Auxiliary wiper blade: Smooths upper fabric during forming to eliminate creases.
Edge presser mechanism: Applies localized pressure along the feather edge to ensure full contact between upper and insole before curing.
