Short Description
The TPB-2591E and TPB-2574E are electronic post-bed roller feed sewing machines designed for shoe upper assembly and decorative topstitching. The synchronized wheel feed, driven roller presser and needle-feed system provide accurate material control on curves, narrow edges and three-dimensional components. Single- and double-needle versions are available with automatic thread trimming, backtacking and presser-foot lifting.
Product Overview
TPB-2591E / TPB-2574E Electronic Post-Bed Roller Feed Sewing Machine
The TOPEAGLE TPB-2591E and TPB-2574E are electronic post-bed lockstitch sewing machines developed for shoe upper production, leather goods and other three-dimensional sewn products.
Post-bed roller feed machines are among the most widely used sewing machines in footwear manufacturing. The narrow post provides easy access to curved, shaped and difficult-to-reach areas, while the small contact area of the roller presser gives the operator precise control around tight radiuses and narrow edges.
The feeding system combines a driven lower wheel, a roller presser and synchronized needle feed. These feeding actions move the upper and lower material layers evenly, helping reduce material displacement and maintain consistent stitch length on leather, synthetic leather, coated fabrics and multi-layer shoe components.
The TPB-2591E is a single-needle version for general assembly seams and decorative topstitching. The TPB-2574E is a double-needle version designed to produce two parallel rows of stitching in one operation.
The electronic control system allows stitch length and automatic backtacking settings to be adjusted through the color touch-screen panel. Programmable seam functions can be used for repeated sewing operations, target stitches and selected seam sections.
Automatic thread trimming, automatic reverse sewing and automatic presser-foot lifting reduce manual handling between sewing cycles. The integrated direct-drive system provides responsive speed control and helps reduce vibration and energy consumption.
These machines are suitable for leather shoes, sports shoes, casual footwear, safety shoes, children's shoes and other products requiring accurate assembly or decorative seams.
Precise Roller and Needle Feeding
The driven wheel feed, roller presser and synchronized needle feed work together to transport the material accurately through the sewing area.
This feeding system provides several advantages:
Consistent feeding of upper and lower material layers
Better control around small curves
Reduced material marking compared with a wide presser foot
Accurate decorative topstitching
Stable stitch length over material overlaps
Improved handling of three-dimensional shoe components
Electronic Stitch-Length Control
Stitch length can be adjusted through the operation panel. Electronic feed control helps reproduce the selected stitch length when changing sewing speed or sewing direction.
Automatic reverse sewing can be programmed according to the production requirement, reducing manual lever operation and helping align the reverse stitches with the forward seam.
Post-Bed Design for Shoe Uppers
The raised post provides access to shaped shoe-upper components that are difficult to sew on a conventional flatbed machine.
It is especially useful for:
Toe and vamp curves
Quarter seams
Heel sections
Collar and topline areas
Narrow leather components
Preformed shoe uppers
Decorative edge stitching

Product Advantages
One of the Core Machines for Shoe Upper Production
The post-bed structure and roller-feed system make the machine suitable for a wide range of shoe-upper assembly and topstitching operations.
Easy Sewing Around Tight Curves
The small roller presser contact area gives the operator better visibility and control when sewing curved shoe components.
Consistent Material Feeding
The wheel feed, roller presser and needle feed help prevent relative movement between material layers.
Accurate Decorative Stitching
Electronic stitch-length control and precise feeding support clean, repeatable decorative seams on visible shoe-upper areas.
Single- and Double-Needle Options
The TPB-2591E provides flexible single-row sewing, while the TPB-2574E produces two parallel rows in one operation.
Reduced Manual Operation
Automatic trimming, backtacking and presser-foot lifting improve efficiency during repeated short-seam operations.
