Roller Presser Foot / Roller Foot Transformation / Sewing Presser Foot Transformation

This topic should be interesting for many for many reasons, first of all you have a classic standard stitching at home, but you can't sew some heavier materials with it (eco leather, real natural leather, etc.). This "transformation" could be a very good solution for you. Otherwise, the transformation in question in today's topic can be applied to a large number of Yuki and Singer machines (partial list at the bottom of the post), to add that this transformation is performed mainly on machines with only lower transport. So let's get started:

Ova tema bi trebala za mnoge biti interesantna iz dosta razloga, prije svega imate kod kuće klasičnu standardnu štepericu ali sa njom ne možete da šijete neke teže materijale (eko koža, prava prirodna koža i sl). Ova "transformacija" bi mogla biti za Vas jedno vrlodobro rješenje. Inače transformacija o kojoj je riječ u današnjoj temi se može primijeniti za veći broj Juki i Singer šteperica (djelimični spisak na dnu posta), još da dodam da se ova transformacija vrši uglavnom na mašinama samo sa donjim transportom. Pa da krenemo:

There is a "Yuki 555" type sewing machine on the table (Fig. 1), which needs to be done first; therefore, we first remove the bobbin case with the coil from the machine, open that sliding plate, or remove it completely, unscrew the screws that hold the piercing plate and the foot (Fig. 2), when we have done that, unscrew the two screws that hold the lower transport teeth (feed dog). .3).

Na stolu je šteperica tipa "Juki 555" (sl.1), šta je potrebno prvo uraditi; dakle, uklanjamo prvo čunak sa bobinom iz mašine, otvaramo onu kliznu pločicu, ili je skinemo u potpunosti, odvijamo vijke koji drže ubodnu pločicu i stopicu (sl.2), kada smo to uradili odvijamo i dva vijka koji drže donje transportne zupce (sl.3).

To emphasize that unscrewing individual screws can be difficult, especially on the lower conveyor, for example, it is necessary to have a slightly longer screwdriver and of course a little persistence.

In Figure 4 we see this kit that we will use to transform the machine. It consists of: needle plate, feed dog and roller foot.

Da naglasim, da odvijanje pojedinih vijaka može ići teško, pogotovo recimo na donjem transporteru, potrebno je imati nešto duži izvijač (šavciger) i naravno malo upornosti. Na slici 4 vidimo taj komplet (kit) koji će mo koristiti za transformaciju mašine-stroja. Sastoji se od:ubodne pločice, donjeg transportera i kotrljajuće stopice (roller foot).

Since we have already removed everything that needs to be removed, now we first install a new lower conveyor-feed dog, center it nicely and tighten it with screws, it doesn't have to be too tight, then we put a needle plate (Fig. 5).

Pošto smo sve već prethodno sve što treba skinuli, sada prvo postavljamo novi donji transporter, lijepo ga centrirati i pritegnuti sa vijcima, ne mora to biti neko prejako stezanje, zatim stavljamo ubodnu pločicu (sl.5).

Since this rolling foot is a bit "higher" than the usual one, it is necessary to raise the foot bar by a few millimeters (it all depends on which model is in question), it is not complicated with these types of machines, we remove the side cover ( Fig.6), unscrew the upper large spring tension screw to the end, then unscrew the two screws holding the foot bar, just enough so that the bracket can move upwards.

Pošto je ova kotrljajuća stopica nešto "visočija" od obične, potrebno je i nosač stopice (foot bar) za nekoliko milimetara podići prema gore (sve zavisi koji je model u pitanju), nije to ništa komplikovano kod ovih tipova mašina, skinemo bočni poklopac (sl.6), odvijemo gornji veliki vijak za napetost opruge do kraja, zatim dva vijka koji pridržavaju nosač stopice odvijemo djelimično, tek toliko da se nosač može pomijerati prema gore.

Further, we take the rolling foot and place it in the intended place, tighten it with a screw (Fig. 7) and with another smaller screw with a lock nut fix the rolling part EXACTLY to the lower transport teeth, when we do that, we try to raise the foot to the end position. you need to lift the sliding sleeve through which the footrest moves, unscrew the retaining screw and raise the sleeve for as long as necessary, moving that sleeve can also be harder, so spray it a little and "arm" yourself with enough patience ☺, it will be worth it .!

Dalje; uzimamo kotrljajuću stopicu i postavimo je na predviđeno mjesto, pritegnemo vijkom (sl.7) a drugim manjim vijkom sa kontra navrtkom (maticom) fixiramo kotrljajući dio TAČNO na donje transportne zupce, kada to uradimo, pokušamo podići stopicu u krajnji položaj gore, ako ne ide onda se treba podići i klizna čahura kroz koju se kreće nosač stopice, odviti vijak za predržavanje i podići čauru za onoliko koliko je potrebno, pomicanje te čahure zna isto ići teže pa malo je pošpricajte i "naoružajte" se sa dovoljno strpljenja :), vrijedit će .!

In Figure 8 we see the completion of the transformation. Note: NEVER keep the rolling part on the conveyor if there is no material in between as protection, as this protects the lower teeth from unnecessary damage (metal to metal), when winding the thread and when not using the machine, BE SURE to raise the foot (Fig. 9). So let’s give it a try, take two pieces of artificial leather or some other material and try it on, possibly tweaking the tension of the lower and upper thread, depending on the thickness.

Na slici 8 vidimo završetak transformacije. Napomena: NIKADA nemojte držati kotrljajući dio na transporteru ako između nema neki materijal kao zaštita, jer time čuvate donje zupce od bespotrebnog oštećenja (metal na metal), pri namotavanju konca i kada ne koristite mašinu
OBAVEZNO podići stopicu (sl.9). Pa da probamo, uzeti dva komada eko kože ili nekog drugog materijala i isprobati, eventualno dotjerati napetost donjeg i gornjeg konca, ovisno o debljini.

How this transformation "turned out" can be seen by the result and the stitch in Figures 10 and 11, the thread used is 20. What else should be noted at the end, for stronger materials use a lower number of revolutions, it is desirable that the engine is slower and reduce the engine pulley to at the very least, it is necessary with extremely strong materials, with this artificial leather and thicker fabric it is not something necessary.

Kako je ova transformacija "ispala" vidi se po rezultatu i štepu na slikama 10 i 11, korišteni konac je 20.Šta još treba napomenuti na kraju, za jače materijale koristiti manji broj okretaja, poželjno je da je motor sporiji a remenicu motora smanjiti na najmnju mjeru, to je potrebno kod izrazito jačih materijala ,kod ove vještacke-eko kože i deblje tkanine nije nešto neophodno.
