Construction factors• The force generated by the motor system when

trying to drive needles through these materials is quite immense.

• Therefore, all-metal sewing machines are best for sewing these materials primarily because sewing machines that are housed in other material such as plastic can’t handle these materials without breaking down.

• Sticking to metal body sewing machines gives these material workers an easier time sewing tough or thick materials and also helps them save money on maintenance of the machines.

Motor rating

Sewing machines for heavier materials such as leather, denim, canvas and upholstery need powerful motors that are usually rated according to the amount of currency they draw.

The most common motors are 1.2-amp and 1.5-amp, but anything less is insufficient.

On the other hand, highly effective motor systems include precision engineered devices such as reduced gear systems and ribbed drive belts that help eliminate the tendency for these materials to slip when being sewn.

Attachment systems

• Almost all sewing machines use the ordinary feed dog system.

• However, a few heavy duty machines implement have additional specialty mechanisms.

• These add-ons are primarily for reducing friction between sticky materials and the presser foot as well as improving the ability for the materials to move along evenly without bunching up.

Walking foot attachment

• A feed foot or walking foot is basically a combination style foot.

• A walking foot has two presser feet. • One presser foot is on the outside and the other

one on the inside and they alternate oscillating up and down as the sewing machine moves the needle.

• The walking foot ensures that these materials are always held in place especially when the needle is puncturing the materials and lifting out of it.

Rolling presser foot attachment

• This is a presser foot attachment that has small rollers or wheels that allow sticky material to move forward easily without sticking to the system.

• However, it is essential to understand that depending on the type of roller foot, omnidirectional dewing may be more difficult.

• The leather, denim, canvas or upholstery is free to move in between these two stages.

Walking foot machines

• Walking foot machines are ideal for working with multiple layers of dense vinyl, tough denim upholstery and thick leather.

• They allow the stitcher to move around and zigzag in all directions with ease while still preventing missed stitches or slippage.

• In addition to the feed dog, the walking foot machines move the thicker materials with a combination of several different methods and they have a pair of presser feet instead of just one.

Needle compatibility

• Some needles are more suitable for sewing tough materials.

• Needles that have thicker shanks are generally tougher and they can puncture lather without snapping or bending.

• On the other hand, they have wider bodies so they can easily pull the treat through the holes without snagging the leather on the edges.

• Most general use needles are made to fit into standard sized holders. However, heavy duty leather needles are only appropriate for leather specific sewing machines.

Drive configurations

There are many different varieties of walking foot machines that are classified according to their drive configurations:

Compound drive or triple feed:In the triple feed system, movements of the

inside presser foot and needle are synchronized with the feed dogs.

The machine is suitable for stitching all heavy materials without causing any stich irregularities

Double feed driveDouble feed drive sewing machines move the

material by moving the feed dogs in concert with the outer presser foot.

This makes it ideal for sewing mark-proof leather.

Jump feed driveIn these sewing machines, a slotted presser

foot usually lifts up in order to allow the needle to move the material.

Jump feed drive is ideal for thick harness projects and leather because it moves the material with the current stitch.

Presser foot feed driveIn this sewing machine, the presser foot has

teeth on the surface. Although the presser feet in most general use

sewing machines are smooth, this particular feed has teeth in order to ensure that the pressure foot always gets a strong grip on the leather.

Unfortunately, the teeth may leave little marks especially on soft leather that has been vegetable tanned.

Snap feed drive

This system uses the feed dog to move the material by simply pulling it from the bottom.

The hinge is loaded with springs so when it’s feed dog drops, the foot lifts and snaps forward.

Snap feed drive works well with projects where it’s necessary to pivot the leather while sewing. The ideal machine for sewing largely depends on the type and thickness of material.

It’s essential to remember that some sewing machines are more appropriate for common items such as motorcycle saddle bags and holsters .
