The workhorse for a sewing room built around straight stitch
Choose the A7100 when most of your work is straight seams and you want the speed of an industrial machine without wasting movement on thread tails, repeated backtacks and lifting the foot by hand.
Apparel makers
Create clean straight construction seams on common light-to-medium garment materials.
Home studios
Step into industrial sewing with a controllable speed ceiling and automatic workflow.
Production rooms
Reduce repetitive handling across batches of the same seams and operations.
Homewares
Sew pillowcases, cushions, bedding, napery and suitable light curtain fabrics.
Training spaces
Set a manageable top speed, then increase it as operator control develops.
Choose by the work, not only the word industrial. The A7100 is a single-needle, bottom-feed straight-lockstitch machine for light-to-medium materials. It does not zigzag, overlock, sew buttonholes or provide the compound feed needed for heavy leather and bulky upholstery assemblies.

Direct-drive difference
Responsive power without the constant idle hum of a clutch motor
The motor is integrated with the machine head, so power reaches the main shaft directly. The A7100 responds quickly when the pedal is pressed and remains quiet when you pause.
- Immediate start and stop response
- Adjustable maximum speed from the control panel
- Lower idle noise than a traditional clutch-motor workstation
- No separate under-table drive motor taking up knee space
- Energy use is concentrated around active sewing
Three automatic functions remove the motions repeated on every seam
The A7100 keeps the actual sewing familiar while automating the beginning and end of each operation. That difference becomes valuable across alterations, sample making and production work.
Finish the pedal sequence and the machine cuts the needle and bobbin threads, reducing scissor work and long thread tails.
Set reverse stitches at the beginning and end for consistent seam locking across repeated work.
Raise the presser foot as part of the pedal-controlled workflow so both hands can stay closer to the fabric.
Set a sensible top speed rather than relying on pedal finesse alone, useful for learning and detailed work.
Use the reverse lever near the needle whenever judgement matters more than a programmed backtack.
Built-in illumination helps you follow seam guides, fabric edges and the needle entry point.
Set the machine around the operator
Industrial speed does not mean sewing flat out
The control panel lets you cap the maximum sewing speed to suit the operator and task. Start conservatively while learning the pedal or working close to an edge, then raise the limit for long production seams.
- Lower speed for curves, corners and precision work
- Higher speed for confident runs on consistent material
- Repeatable backtack settings for batch sewing
- Automatic trim and lift functions selected for the operation
Designed for apparel and general light-to-medium sewing
Woven garments
Cotton, linen, shirting, suiting and many everyday clothing fabrics.
Alterations
Trouser hems, side seams, linings, zip work and common garment repairs.
Suitable knits
Straight-stitch operations using the right DBx1 ballpoint needle and careful testing.
Uniforms
Repeat straight seams on common workwear and uniform materials within its range.
Samples
Fast construction for pattern development, fitting garments and small production runs.
Bedding
Long straight seams on pillowcases, sheets and suitable cover fabrics.
Light furnishings
Cushions, napery and suitable curtain or décor fabrics without bulky layered construction.
Repeat production
Consistent seam starts and finishes when settings are matched to the operation.
Not a walking-foot substitute: choose a needle-feed or compound-feed machine for frequent canvas stacks, upholstery, webbing, heavy leather or materials that creep between layers. The A7100 uses bottom drop feed.
This is a dedicated industrial setup, not a portable domestic machine
The machine head sits in a full industrial table with a steel stand and pedal system.
Industrial cones feed from a raised guide for a clean route into the tension system.
The current package is mounted on wheels so the workstation can be repositioned when required.
Lock the castors and keep the table level before sewing at industrial speed.
Maintain the oil system with the correct clear No. 10 white industrial sewing-machine oil.
Use DBx1 industrial needles and thread selected for the fabric and seam specification.

Open Official Manual (PDF)Zoje A7100 questions answered
What type of machine is the Zoje A7100?
It is an industrial single-needle, bottom-feed straight-lockstitch machine with an integrated direct-drive motor and automatic seam-finishing functions.
What does the A7100 sew?
It is designed for general straight-stitch work on light-to-medium materials, including many apparel fabrics, alterations, uniforms, samples, bedding and suitable homewares.
Does it only sew straight stitch?
Yes. It produces a strong straight lockstitch and reverse lockstitch. It does not zigzag, make decorative stitches, overlock edges or sew buttonholes.
What automatic functions are included?
The current Direct Sewing A7100 package includes automatic backtacking, automatic thread trimming and automatic presser-foot lift.
How does automatic thread trimming help?
The machine cuts the needle and bobbin threads at the end of the programmed operation, reducing scissor work and thread tails between seams.
Can the backtack be programmed?
Yes. Beginning and ending reverse stitches can be set for consistent seam locking. A manual reverse lever remains available when operator judgement is preferred.
Does it lift the presser foot automatically?
Yes. Automatic presser-foot lift is included in the current local machine package, helping the operator keep both hands closer to the work.
What does direct drive mean?
The servo motor is integrated with the machine head and drives the main shaft directly. This gives quick response and avoids the constant idle running of a traditional clutch motor.
Do I have to sew at full industrial speed?
No. Set a lower maximum speed at the control panel, then use the pedal for variable control up to that limit.
How fast can the A7100 sew?
Zoje rates the standard A7100 configuration at up to 5,000 stitches per minute. Actual working speed should be chosen for the material, operation and operator.
What is the maximum stitch length?
The standard A7100 has a maximum stitch length of 5mm.
Which needles does it use?
It uses DBx1 industrial needles, also commonly labelled 16x231. Zoje specifies a size range from #11 to #18 for the standard A7100.
Can I use domestic sewing-machine needles?
No. Domestic 130/705 H needles are a different system. Use DBx1 / 16x231 industrial needles with the point and size selected for the fabric and thread.
Will it sew denim?
It can handle suitable light-to-medium denim garment work with the correct DBx1 needle, thread and reduced speed at bulky intersections. It is not a heavy walking-foot machine.
Can it sew stretch fabric?
It can straight-stitch suitable knit operations with the correct industrial ballpoint needle and testing. It does not have stretch stitches or differential feed, so an overlocker may be the better primary machine for knit construction.
Is it suitable for upholstery or leather?
Only lighter work within its material range. Choose a needle-feed or compound-feed walking-foot machine for regular upholstery, canvas, webbing, heavy leather or bulky layered assemblies.
Does the machine require oil?
Yes. It uses an automatic lubrication system. Maintain it with the specified clear No. 10 white industrial sewing-machine oil and follow the manual for level and maintenance instructions.
Does it include a work light?
Yes. An LED light is built into the sewing area to improve visibility around the needle and seam guide.
How much space does it need?
The current industrial table is approximately 1.2 x 0.6m, plus room for the operator and safe access around the workstation.
What comes with the machine?
The current package includes the A7100 head with integrated motor and controls, industrial table and stand, pedal system, thread stand, wheels, oil, bobbins, screwdriver and needles. Table or stand finish can vary.
Let the machine handle the repetitive finishing steps.
The Zoje A7100 combines responsive direct-drive power with automatic backtacking, thread trimming and foot lift, giving busy sewing rooms more efficient starts, stops and fabric handling.
