CONSEW® 339RBL-25 Heavy-Duty Double Needle 25-Inch Long Arm Compound Feed Walking Foot Industrial Sewing Machine – Complete with Table & Stand
FULLY ASSEMBLED | TABLE, MOTOR & STAND INCLUDED
Prepared and inspected by JMJ Sewing Machines. Caster wheels are not included.
25-INCH LONG ARM • DOUBLE NEEDLE • COMPOUND FEED • WALKING FOOT
The CONSEW 339RBL-25 is a heavy-duty double-needle industrial lockstitch sewing machine designed for professional sewing operations involving large textile panels, layered materials, and parallel seam construction.
Its extended 25-inch long-arm configuration provides additional clearance for handling oversized upholstery panels, canvas products, industrial covers, and other substantial sewing projects.
The compound-feed walking-foot system combines needle feed, bottom feed, and alternating presser feet to help maintain controlled material movement when sewing compatible leather, vinyl, canvas, and industrial textiles.
JMJ Sewing Machines supplies this model as a complete industrial workstation with motor, table, and stand, assembled and prepared for operation.
Key Features
- Double-Needle Lockstitch: Produces two parallel rows of straight lockstitch sewing during a single operation.
- 25-Inch Long Arm: Provides extended working clearance for oversized upholstery panels and substantial textile assemblies.
- Compound Feed Walking Foot: Combines needle feed, bottom feed, and alternating presser feet for controlled material movement.
- Centra-Lube® Lubrication: The supplied product information describes a semi-automatic lubrication system with automatic hook lubrication and an oil-fed take-up mechanism.
- Large Vertical-Axis Rotary Hooks: Designed for industrial sewing operations using large-capacity bobbins.
- Reverse Stitching: Allows seam reinforcement through reverse lockstitch sewing.
- Long Stitch Capability: Listed maximum stitch length of up to 10 mm.
- Adjustable Center Foot: Supports adjustment for compatible material thicknesses and sewing operations.
- Safety Clutch: Helps protect the hook mechanism under certain thread-jam conditions.
- Needle Gauge Options: Different needle-spacing configurations may be available for specialized applications.
- Optional Synchronized Puller: A puller-equipped configuration may be available under the -P model designation. This option is not included in the standard package.
25-Inch Long Arm Workspace
The extended long-arm design provides additional working space between the needle area and the machine body.
This clearance is particularly useful when positioning large upholstery panels, canvas assemblies, protective covers, and other bulky industrial sewing projects.
Compound Feed Walking Foot Technology
The coordinated compound-feed mechanism combines three feeding actions:
- Needle feed.
- Bottom feed.
- Alternating walking presser feet.
This arrangement helps reduce unwanted movement between material layers and supports consistent feeding during compatible industrial sewing operations.
Professional Applications
- Automotive upholstery and interior panels.
- Marine upholstery and boat covers.
- Furniture upholstery and cushion manufacturing.
- Canvas products and outdoor equipment.
- Tarpaulins, tents, awnings, and industrial covers.
- Leather bags, luggage, and travel accessories.
- Heavy-duty apparel and selected footwear components.
- Binding, taping, and piping applications.
- Parallel decorative and functional seam construction.
Actual sewing capability depends on material thickness, needle selection, thread, needle spacing, machine adjustments, and operating conditions. Testing the intended material is recommended.
