First to try to translate this term "roller foot for sewing machine", English is not my strong point but to my knowledge this could be translated as "roller foot", we would say "roller foot" for a sewing machine. Many industrial sewing machines have a rolling foot in the shape of a small wheel, this foot is mostly used in machines for sewing heavier and stronger materials, materials that are in some way "sticky" (rubberized, etc.) and difficult to pass through the machine that have only so called. lower transport of materials, mostly used when working with...
Prvo da pokušam prevesti ovaj izraz "roller foot for sewing machine", engleski mi nije baš jača strana ali po mom znanju ovo bi se moglo prevesti kao "valjak stopalo", mi bi kazali "kotrljajuća-valjkasta stopica" za šivaću mašinu. Mnogi industrijski šivaći strojevi posjeduju kotrljajuću stopicu u obliku jednog manjeg točkića, ta stopica se najviše koristi kod mašina za šivenje težih i jacih materijala, materijala koji su na neki nacin "ljepljivi" (gumirani i sl.) pa teško prolaze kroz mašinu koje imaju samo tzv. donji transport materijala, najviše se koristi pri radu sa...natural and faux leather. On home sewing machines, if you are doing something with heavier materials, try to get a presser foot that has one or more rolling "bodies" of rollers in it, which could make the work much easier. For industrial sewing machines, ordinary stitches can be bought so-called.

Usually, this set indicates for which sewing machine models the set in question is suitable, they are usually universal and are suitable for a larger number of models.
What I want to say :), you have the opportunity to do something with natural leather, but with the machine you own, it is not easy, by buying this "transformation" you could be surprised how much the machine has changed and what it can sew. Of course, since industrial stitches are quite fast and it is not recommended for sewing natural leather, with this "rolling set" it is desirable to reduce the diameter of the drive pulley on the motor to reduce the stitch speed, you need a slightly stronger needle and adequate thread and your new " adventure "can begin..How this transformation is done HERE
