SIRUBA® L917-H1 Single Needle Heavy Material Industrial Lockstitch Sewing Machine - Complete with Table & Stand
FULLY ASSEMBLED | TABLE, MOTOR & STAND INCLUDED
Prepared and inspected by JMJ Sewing Machines. Caster wheels not included.
MEDIUM-TO-HEAVY MATERIALS • STRAIGHT LOCKSTITCH • INDUSTRIAL FLATBED
The SIRUBA L917-H1 is a single-needle industrial straight-stitch machine configured for medium-to-heavy textile work. Its flatbed layout and conventional drop-feed mechanism make it suitable for repeated straight seams on compatible woven materials.
The H1 subclass is designed for heavier sewing applications than light-duty versions in the L917 family. Actual material suitability depends on the thickness and structure of the workpiece, the needle and thread selected, and the machine's adjustment.
JMJ Sewing Machines supplies this product as an assembled industrial workstation with machine head, motor, table and stand.
Key Features
- Single-Needle Lockstitch: Creates straight seams for garment assembly and compatible industrial textile work.
- H1 Heavy-Material Configuration: The manufacturer's L917 documentation identifies H1 for medium-to-heavy applications.
- Flatbed Work Surface: Supports garment panels and other flat textile pieces during sewing.
- Drop Feed: Standard lower feeding moves material beneath the presser foot.
- Adjustable Stitch Settings: Supports stitch-length and thread-tension adjustments appropriate to the operation.
- Motor Included: Supplied with a motor as part of the JMJ assembly; confirm the exact motor model and electrical rating for the unit ordered.
- Lubrication: Follow the oiling instructions and lubricant specification provided for the supplied machine.
Applications
- Denim, canvas and structured woven fabrics within the machine's sewing capacity.
- Uniforms, workwear and heavier garment components.
- Fabric bags, covers and other straight-seam textile products.
- Alterations and production work requiring a heavy-material lockstitch setup.
This is a drop-feed machine, not a walking-foot machine. For difficult multilayer upholstery or heavy leather, ask JMJ to evaluate whether a compound-feed machine is more suitable.

JMJ Quality Inspection & Sewing Test
Before delivery, JMJ Sewing Machines performs a thorough inspection intended to identify possible manufacturing defects, assembly concerns and operating issues. Our team checks accessible mechanical components, the workstation and motor operation.
As appropriate, technicians check lubrication, make adjustments and calibration, and perform a sewing test to assess stitch formation and feeding.
Our objective is to deliver equipment prepared and checked for proper operation. These preventive steps reduce risk but cannot guarantee that a defect will never occur.
Complimentary In-Store Operating Explanation
Machines purchased directly at the JMJ Sewing Machines physical store in Orlando, Florida include a brief complimentary explanation of basic controls and operation at pickup. This is introductory guidance rather than an extended training course and does not apply as an in-person service to shipped orders.

Coverage, exclusions, duration and the responsible warrantor depend on the applicable manufacturer or seller warranty terms.
JMJ Sewing Machines Recommends
The SIRUBA L917-H1 is worth considering for shops sewing straight seams on medium-to-heavy woven materials. Before ordering, tell our team the fabric type, number of layers and thread size so we can help assess whether this drop-feed model is the right choice.
