Short Description

The TF-62D is a direct-drive, 4-needle, 6-thread feed-off-the-arm flatseamer designed for joining knitwear, sportswear, thermal underwear, socks and other stretch garments. Its small cylinder bed, adjustable differential feed and individual thread-tension controls help produce smooth, flexible and consistent flat seams on tubular and elastic materials.

Product Overview

TF-62D Direct-Drive Feed-Off-the-Arm Flatseamer

The TOPEAGLE TF-62D is a direct-drive, 4-needle, 6-thread feed-off-the-arm flatseamer designed for joining stretchable knitted fabrics with a smooth and low-profile seam.

Its feed-off-the-arm cylinder-bed construction provides convenient access when sewing tubular and three-dimensional garment components. The circumference around the needle-drop area is approximately 148 mm, allowing the operator to handle smaller tubular parts such as sleeves, underwear sections, sock components and narrow sportswear panels. The 200 mm cylinder length before the needle position provides additional working space for garment handling.

The adjustable differential-feed system helps control fabric stretching, gathering and layer movement. It supports stable feeding on materials ranging from single jersey to fleece, as well as stretch fabrics and sections with changing thickness. The overlap between the upper and lower fabric edges can also be adjusted according to the required seam construction. Similar professional feed-off-the-arm flatseam platforms emphasize differential feeding, small-cylinder handling and control over stretch and uneven fabric layers.

The sealed lubrication structure helps minimize the risk of oil reaching the sewing area, while individual thread-tension adjustment allows the operator to balance the needle and looper threads for a neat seam appearance.

Single-edge and double-edge trimming configurations are available according to the selected subclass. Models ending in "-7" can be supplied with automatic thread-chain cutting to reduce manual trimming after each sewing cycle.

The TF-62D is suitable for knitwear factories, sportswear manufacturers, underwear producers, hosiery workshops and other garment manufacturers requiring flexible, comfortable and durable flat seams.

Main Applications

Knitwear, Sportswear, Activewear, Compression garments, Thermal underwear, Men's underwear, Women's underwear, T-shirts, Leggings, Base layers, Socks and hosiery products, Swimwear,Selected wetsuits and diving suits, Stretch workwear, Seamless-look knitted garments

Typical Sewing Operations

Flat joining of two fabric panels

Sleeve closing

Side-seam joining

Crotch seams

Shoulder joining

Legging and sportswear panel joining

Underwear assembly

Tubular component sewing

Decorative flat seams

Joining elastic knitted materials

Trimming and flatseaming fabric edges in one operation

Professional flatseamer platforms are commonly configured differently for sleeve closing, underwear crotch seams, shoulder joining, tape attachment, light fabrics and surf-suit materials. Therefore, the exact TF-62D subclass should be selected according to the garment and seam rather than simply by garment name.

Suitable Materials

Single jersey, Interlock knit, Rib knit, Fleece, Lycra and elastane blends, Polyester sportswear fabric, Nylon stretch fabric, Thermal knitted fabric, Compression fabric, Lightweight laminated stretch fabric,Selected rubber-backed or neoprene materials

Material suitability depends on fabric thickness, elasticity, surface friction, trimming requirements and seam construction. A sewing test is recommended for neoprene, rubber-backed or highly adhesive materials.

Product Advantages

Flat and Comfortable Seams

The multi-needle flatseam construction joins fabric panels with a low-profile seam, helping reduce bulky seam allowances in close-fitting garments.

Suitable for Stretch Fabrics

Adjustable differential feed helps control elastic knitted materials and reduces unwanted stretching or gathering.

Easy Tubular Sewing

The compact cylinder circumference provides better access to sleeves, underwear sections, socks and other small tubular components.

Stable Feeding at Thickness Changes

The feeding and overlap-adjustment systems help the operator handle joined seams, elastic intersections and uneven fabric sections.

Cleaner Garment Production

The sealed lubrication structure helps reduce the risk of oil contamination around the sewing area.

Flexible Production Configurations

Different subclasses can be selected according to fabric weight, seam construction, trimming requirement, needle gauge and automatic cutting requirement.

FAQ

What is a 4-needle, 6-thread flatseamer?

A 4-needle, 6-thread flatseamer is an industrial sewing machine used to join knitted or stretch fabric panels with a flat, flexible seam. It is widely used for sportswear, underwear, knitwear and other close-fitting garments.

What does feed-off-the-arm mean?

Feed-off-the-arm refers to the narrow cylinder-bed structure extending from the machine body. It allows tubular garment components to pass around the arm and provides better access to sleeves, underwear, socks and narrow panels.

What is the difference between a flatseamer and a coverstitch machine?

A flatseamer is primarily designed to join two fabric edges into a flat seam. A coverstitch machine is commonly used for hemming or covering an existing seam. The term "flatlock machine" is sometimes used loosely for both, so the actual seam construction should be confirmed.

What materials can the TF-62D sew?

It is suitable for single jersey, interlock, fleece, elastic sportswear fabrics, thermal knits and other light- to medium-weight stretch materials. Special or sticky materials should be tested before ordering.

Is the TF-62D suitable for sportswear?

Yes. It can be used for leggings, activewear, compression garments, base layers and other products requiring flexible flat seams.

Can it sew socks?

Selected subclasses can be configured for sock and hosiery operations. Customers should provide a sock sample and seam requirement to confirm the correct cutter, gauge and sewing parts.

Can it sew wetsuits or diving suits?

A suitable subclass can be used for selected wetsuit or diving-suit materials. Compatibility depends on the neoprene thickness, surface coating, elasticity and required seam.

What needle gauges are available?

The published needle-gauge options are 5.2 mm and 6.0 mm.

What is the maximum sewing speed?

The published maximum sewing speed is 4,000 stitches per minute. Actual production speed should be adjusted according to fabric, thread, trimming configuration and seam quality.

Does the machine have differential feed?

Yes. The differential feed can be adjusted externally to control fabric stretching, gathering and feeding balance. The exact adjustment range should be confirmed.

What is the difference between single-edge and double-edge trimming?

A single-edge trimmer cuts one fabric edge before the seam is formed. A double-edge trimming configuration cuts both fabric edges to prepare a consistent overlap. The correct configuration depends on the garment operation.

What does the "-7" suffix mean?

The "-7" version is supplied with an automatic thread-chain cutting function, subject to the final machine configuration.

What information should customers provide before ordering?

Customers should provide:

Garment type

Fabric composition

Fabric weight and thickness

Fabric elasticity

Required seam sample

Needle gauge

Single- or double-edge trimming requirement

Requirement for automatic chain cutting

Production speed

Voltage and frequency

Fabric and garment samples for testing
