TSH-2619 Goodyear Welt Inseam Stitching Machine

The TOPEAGLE TSH-2619 is a specialized inseam stitching machine for the production of Goodyear-welted footwear. It joins the welt, lasted upper and insole rib with a strong single-thread chainstitch, forming the important internal seam used in traditional welted shoe construction.

During sewing, the awl first pierces the assembled shoe components, while the sewing needle and thread-forming mechanism complete the chainstitch. This coordinated needle-and-awl action allows the machine to penetrate thick, shaped footwear components and produce a secure inseam around the shoe.

The electronic speed-control system provides smooth and stepless adjustment, allowing the operator to control the shoe carefully around the toe, waist and heel areas. Computer-controlled needle positioning helps improve operating convenience and stitch control.

Different welt guides can be supplied according to the welt material, width and profile. The machine is suitable for leather and synthetic welts and can be configured according to the customer's footwear construction and production requirements.

Product Advantages

Professional Inseaming Operation

The TSH-2619 is designed specifically for the internal welt seam rather than general shoe-upper or outsole stitching.

Strong Needle-and-Awl Penetration

The awl prepares the opening before the sewing needle passes through the assembled materials, making the machine suitable for thick and shaped footwear components.

Controlled Sewing Around the Shoe

Stepless electronic speed adjustment allows the operator to control the machine around curved and difficult sections of the shoe.

Flexible Welt Configuration

Different guides can be selected according to welt width, shape and material.

Reliable Industrial Operation

Automatic lubrication and servo-motor control support stable production and reduce routine manual operation.

Technical Specifications

How Does the TSH-2619 Work?

The operator presents the lasted shoe to the sewing area with the sole facing upward. The welt is guided into position along the insole rib.

During each sewing cycle:

The awl penetrates the welt, upper and insole-rib assembly.

The machine feeds the shoe to the next stitch position.

The sewing needle carries the thread through the prepared opening.

The stitch-forming mechanism completes the single-thread chainstitch.

The process continues around the shoe to form the inseam.

The welt can then be trimmed and prepared for the following outsole-attaching process. The outsole is stitched to the welt by a separate outsole stitching machine.
