TSH-2619 Goodyear Welt Inseam Chainstitch Sewing Machine

The TOPEAGLE TSH-2619 is a specialized industrial sewing machine designed for the Goodyear welt inseam stitching process.

It joins the welt, lasted upper and insole rib to form the internal inseam of Goodyear-welted footwear.

Using a coordinated needle-and-awl mechanism, the machine penetrates the assembled shoe components and forms a strong chainstitch along the welt. Its electronic speed-control system allows operators to adjust sewing speed smoothly when working around the toe, waist and heel sections of the shoe.

Key Features

1. Specialized Goodyear Welt Inseam Stitching

Designed specifically for joining the welt, lasted upper and insole rib during Goodyear-welted shoe production.

2. Needle-and-Awl Stitching Mechanism

The awl prepares the material penetration point before the sewing needle and thread-forming mechanism complete the chainstitch.

This coordinated mechanism is suitable for the thick and shaped components used in welted footwear.

3. Strong Chainstitch Formation

Produces a single-thread chainstitch for securing the welt to the lasted upper and insole rib.

4. Stepless Electronic Speed Control

The electronic control system provides smooth sewing-speed adjustment, allowing operators to control stitching around curved shoe sections.

5. Computer-Controlled Needle Positioning

The needle-positioning function helps improve operating convenience and control during sewing.

6. Automatic Lubrication System

The automatic lubrication system supplies oil to relevant machine components to support stable operation and reduce routine manual lubrication.

7. Flexible Welt Guide Options

Different welt guides can be supplied according to welt width, profile and material.

8. Suitable for Leather and Synthetic Welts

Designed to work with leather and synthetic welt materials used in different Goodyear-welted footwear constructions.
