High-Performance Pincer Mechanism

At the heart of the TH-727A is its advanced pincer mechanism, designed to handle multiple points of tension during the side-lasting process. This system consists of multiple (typically 9 or more) independently controlled pincers that work in unison or sequence to grip, pull, and position the upper along the last. Each pincer is designed for fine control, allowing for customized grip strength and angle adjustments to suit different shoe sizes, designs, and material properties. The result is a perfectly stretched upper that conforms to the last with no manual intervention, saving time and eliminating inconsistencies. This pincer mechanism contributes significantly to overall machine efficiency and quality, making the TH-727A indispensable for modern, high-volume production environments.

Servo-Driven Operation for Accuracy and Efficiency

The TH-727A incorporates a servo-driven control system, delivering exceptional accuracy in movement, pressure, and timing. Unlike traditional mechanical systems, servo motors allow the machine to adapt dynamically to varying production needs without sacrificing performance or speed. This servo system powers key elements such as the pincer arms, pressing mechanisms, and adhesive control (where applicable), ensuring smooth operation and consistent output. It reduces mechanical wear and provides finer control over process variables like side tension, lasting angle, and pressing duration. This level of precision is particularly important when producing complex shoe designs or working with sensitive materials that require careful handling.

Time-Saving and High-Productivity Design

Designed with speed in mind, the TH-727A features an optimized workflow that reduces cycle times and increases daily output. The automatic adjustment capabilities and programmable shoe memory functions allow operators to switch between different shoe types quickly, minimizing downtime and boosting production capacity.

Quick setup functions, smart calibration, and programmable operations allow the operator to move from one shoe size or model to another with minimal readjustment, significantly enhancing workflow efficiency.

Intelligent Shoe Model Memory System

The TH-727A is equipped with an intelligent memory system capable of storing multiple shoe models and lasting configurations. This feature allows operators to preprogram settings for specific shoe styles, including pincer tension, pressing force, lasting time, and alignment preferences. These settings can be retrieved instantly, allowing fast changeovers between different production runs. This is particularly beneficial in environments that handle multiple styles or cater to custom orders. The ability to recall specific settings for each model enhances production repeatability and consistency, resulting in fewer defects and better quality control.

Strong Side Pressing for Secure Lasting

In addition to its high-precision pincers, the TH-727A includes a powerful side pressing mechanism that ensures firm and even contact between the upper and the midsole or insole. This side pressing system eliminates gaps, strengthens the bond, and contributes to the ergonomic shape of the final product. The pressing mechanism is adjustable, allowing for fine control of pressure levels according to the type and thickness of materials used. Whether working on soft athletic shoes or firm safety footwear, the machine can apply just the right amount of force to ensure lasting integrity. The pressing elements are also designed with wear-resistant materials and cushioned pads to avoid marking or damaging delicate upper surfaces during compression.
