It provides unmatched performance in terms of accuracy, production output, and long-term reliability, making it an indispensable tool for manufacturers who prioritize product quality, process flexibility, and operator efficiency.

Overview of TH-739A Capabilities

The TH-739A is a computer memory control automatic toe-lasting machine with 9 independent pincers, specially designed for precision toe-lasting operations across various shoe types. The machine is capable of memorizing up to 100 shoe models, thereby reducing the setup time between production runs. Its newly designed last supporter features digitally displayed adjustment with up to 0.1mm precision, giving manufacturers consistent and repeatable results with minimum downtime . Additionally, the TH-739A is fitted with dual-speed rising modes, allowing operators to select between two pre-configured speeds based on the type of material or design complexity. This is especially useful when working with fragile vamps or premium shoe materials. For factories with varied production demands, the TH-739A can be equipped with optional modules such as auxiliary wipers and automatic cementing mechanisms, further increasing its versatility.

Key Features and Functional Advantages

Digitally Adjustable Last Supporter

One of the standout innovations of the TH-739A is the digitally adjustable last supporter system. Traditional toe-lasting machines rely heavily on manual adjustments, which are time-consuming and error-prone. The TH-739A introduces a modernized solution with:

• External rapid adjustment system: Easily accessible knobs and sliders allow operators to make fine-tune adjustments without dismantling machine parts.

• Digital position indicators: Show the exact height and drafting point settings in real-time with a repeatability precision of 0.1mm.

• Quick changeover: Ideal for factories switching between multiple shoe styles, reducing setup time and increasing daily output.

Dual Speed Rising Modes

The TH-739A allows the last supporter to rise with two selectable speeds, giving operators flexibility when handling different shoe materials:

• Fast mode: Increases throughput for rugged, high-durability materials like leather.

• Gentle mode: Designed for delicate vamps or finely detailed upper structures to prevent damage and ensure perfect toe formation.

This adaptability enhances the machine's performance across a wide range of shoe categories—from athletic sneakers to premium formal shoes.

Optional Cementing and Wiper Add-Ons

Depending on factory setup and product needs, the TH-739A can be upgraded with:

• Auxiliary wipers: Ensure the material is evenly and tightly wrapped around the last before cementing.

• Automatic cementing mechanism: Applies adhesive consistently and efficiently, reducing operator workload and minimizing waste.

This modularity is ideal for manufacturers looking to customize production lines without investing in entirely new machinery.

Encoder-Controlled Lasting Mode

Traditional mechanical adjustments require time-intensive calibration. The TH-739A leverages an encoder-based control system to automate and accelerate this process:

• Instant configuration change via software settings.

• Eliminates human error from manual adjustments.

• Faster setup for each shoe model.

• Reduced training requirements for operators.

With encoder control, each step of the toe-lasting process can be digitally managed for maximum efficiency.

Shoe Model Memory

Another critical advantage of the TH-739A is its computer memory capacity to store up to 100 unique shoe models:

• Easy program recall for repeat orders.

• Faster transition between different shoe designs.

• Improved consistency in product output.

• Ideal for short-batch production or just-in-time manufacturing environments.

Operational Workflow

The TH-739A follows a streamlined toe-lasting process that can be optimized for different shoe types:

1. Last Insertion: The shoe last is securely positioned into the machine.

2. Toe Alignment: The toe section of the upper is precisely aligned using adjustable guides.

3. Last Supporter Engagement: Controlled by digital indicators to the desired height and position.

4. Pincer Action: Nine independent pincers grip and shape the upper over the last.

5. Optional Cementing: Adhesive is applied via an automatic cementing system, if installed.

6. Final Lasting and Holding: The toe shape is finalized with controlled pressure and temperature to set the form.

7. Model Storage or Recall: Settings are stored or retrieved for rapid processing of the next pair.
