Product Image Credits: SewingMachinePlus.com

This is a high-quality, high performance single-needle electrically-powered zig-zag sewing machine that comes along with an assembled table and an Uberlight LED lamp for illuminating the workspace during dim or dark lighting conditions.

The lamp is offered free of charge. It is specially designed for high-speed zig-zag stitching which gives the user an edge in terms of high productivity with minimal resource loss.

This machine is suited for working on both light and medium-weight fabrics, including applique, synthetic fabrics, canvas; and it can also handle heavy fabrics.

It is powered by a durable, energy-efficient, and low-noise DC servomotor whose motor housing and mounting are designed to minimize vibration, while maintaining a superb build quality. This model is designed and built by Reliable Corp, and its model number is 2400SZ.

The compactly-built sewing machine is shipped inside a well-sealed package that features a tamper-sensitive seal.

It is shipped alongside its assembled table, which features the motor mount and heavy-duty steel legs. This table has 2 legs that rest on 2 feet (a foot for each leg), with each foot resting on 2 caster mount blocks.

This also means that 4 caster wheels can be fitted to the table thereby allowing the user to wheel the sewing machine around the workplace.

The table legs have an I-shaped cross-section, and they are made from 3/32inches thick steel.

Each table leg features 2 metal frames, with the top frame being capable of sliding along the bottom frame, and this allows for the table height to be adjusted by adjusting how deep the top frame slide into the bottom frame.

The table top is made of high-quality plywood and features a well cut-out region surrounded by bolt holes where the machine bed of the sewing machine can be mounted and bolted securely to the table.

The LED light included in the package is the high-quality SMD-LED lamp, Uberlight 3000TL, which normally retails for USD79, but is offered free of charge to people who acquire this machine from authorized dealers. The color scheme of the sewing machine is white.

This specialty zig-zag sewing equipment has an exceptional stitch width of 10mm. The stitch is the maximum distance the needle can move side-by-side while sewing a fabric.

Its stitch width indicates that the maximum amplitude of the zig-zag is 10mm, which is adequate for creating various types of zig-zag stitch formations.

Still, one can adjust the stitch width to an appropriate value using the easy-to-access and simple-to-use stitch width dial on the front panel of the machine.

This machine allows for stitch formations to be created in either direction (front or back) on the same workpiece.

If one is stitching the fabric in a specific direction, it is still possible to immediately reverse the stitching direction without damaging the workpiece.

This is made possible by the reverse lever mechanism, which also allows the user to easily create perfect and well-aligned back-tacks.

This non-computerized electronic machine is powered by a SewQuiet 6000SM brushless servomotor whose 12-coil design endows it with a high torque and power.

This motor can draw a maximum of 550watts, and must be powered by either a 110Volts or 220Volts, 4.5amperes AC power.

Likewise, it can achieve a maximum speed of 6000revolutions per minute(rpm). The maximum power output from the motor is 0.75horsepowers (HP). Even so, this motor assembly comes without a synchronizer.

This motor allows the machine to make a maximum of 2,800stitches per minute (SPM). The stitch length is adjustable, with the maximum length being 5mm. This length adjustment can be done using the stitch dial regulator.

This machine has a large hook capacity which optimizes its stitching performance. This hook assembly is manually lubricated, while the rotary hook hub is auto-lubricated as the machine runs.

The machine bed-size is 18.5inches long, and its large workspace (which is 11.25inches long) allows for relatively large workpieces to be stitched together easily.

The presser foot can be raised up or lowered down, and this can be achieved using a knee mechanism or be done manually by the user simply lifting the presser foot away from the needle plate.

The knee-lift can raise the foot up through a distance of 15mm, while manual lift achieves a maximum raise of only 8mm, which is still enough to fit in thick fabrics such as quilts for zig-zag stitching to be done on them. The needle bar securely holds the 135X7 needle in place.

This model comes with its easy-to-follow instruction manual along with the installation hardware tool-kit and thread stand. There is also a drawer that can be fitted to the stand.

The Reliable 2400SZ is supported by a 12-month limited warranty.

Zig zag sewing machine buyer's guide

The needle-thread assembly

Sewing machines are professional-grade equipments designed for stitching various types and grades of fabrics using threads.

For this reason, the most important part of the machine is the needle-thread assembly, with the rest of the machine parts playing a supporting role.

The needle-thread assembly works to create various types of stitches on the fabric(s) being worked on.

Multiple stitch formations

All high-quality sewing machines have the capacity of creating multiple stitch formations on fabrics.

These stitch formations can be broadly categorized into 3 types; plain formations, patterned formations, and decorative formations.

The basic formations are the plain stitch formations, and when they are manipulated professionally, they can create patterns or decorations that form the basis of the patterned and decorative stitch formations respectively.

There are 4 main categories of plain stitches; the chain-stitch, cover-stitch, lock-stitch, and the overlock. The chain stitch and lock-stitch are described below as they are the antecedents of the zig-zag stitch.

The chain stitch

The chain stitch is the most basic of the 4 plain stitch formations. The chain stitch is analogous to the running stitch of hand sewing and the stitch created is not self-locking.

The stitch is created when the needle bar pushes the needle through the needle plate (and the fabric placed atop it) and the pulling it out as the feed dogs drag the fabric along the plate so that the needle can pierce the fabric in the adjacent unstitched area.

The process of the needle descending down and going through the fabric workpiece and the needle plate and then being pulled up is called a stitching cycle as it allows the needle to create one complete stitch.

Because individual stitches are not self-locked, if any of the stitches is cut, a whole length of stitches can unravel till a tied (that is, a locked) stitch is encountered.

This can cause the fabric to be ripped apart. Another drawback of chain stitches is that sewing can only be done in one direction.

The lock stitch

A much improved version of the chain stitch is the lock-stitch in which two different threads are used; one thread is attached to the needle while the other is wound around a bobbin driver placed underneath the needle plate.

When the needle goes through the fabric and needle plate, it hooks and then interlaces with the thread from the bobbin.

The interlaced threads are pulled up through the needle plate to come and rest on the underside of the fabric hence the interlaced bobbin thread predominates on the underside of the garment while the needle thread forms the stitch loop on the top of the garment.

The zig zag stitch formation

Sometimes, one needs to use a lock stitch to join to 2 fabrics edge-to-edge or wants to stitch elastic fabrics.

In this instances, the straight lock stitch is inappropriate, and it needs to be modified such that any 2 adjacent stitches form an acute angle, and this creates a zig-zag stitch formation of lock-stitches.

To create a zig-zag stitch, the needle of the machine needs to be controlled by a cam which ensures that the needle moves side by side during each stitching cycle.

This side-by-side needle motion occurs concurrently as the feed dogs move the fabric along the needle plate, and this ensures that the stitch made is diagonal rather than horizontal, and any 2 joined diagonal stitches start to create a zig-zag stitch pattern.

The angle between these 2 diagonal stitches, as well as the individual length of each stitch can be adjusted so as to create wide, long, short, or narrow zigzag formations.

The blind stitch

There is also a variant of the zig-zag stitch called the blind stitch (also called blind hem) in which a pair of the zigzag (that is 2 adjoining diagonal stitches) is separated from the next pair by a series of straight lock stitches.

This blind hem works well to create an almost invisible hem in the fabric.


The zig zag sewing machine

There are sewing machines purposely built to stitch zig-zag formations, along with the blind hem, on fabrics and garments. These specialized equipments are called zig-zag sewing machines.

There are 2 main categories of zig-zag sewing machines; the manually-operated (also called mechanical) models, and the electrically-powered (also called electronic) models. Electronic machines are further divided into computerized and non-computerized models.
