A Portuguese machine cuts and forms collars from the same jersey fabric as the garment body, using metal pins to keep the material flat and aligned. No separate rib fabric needed. The collar matches perfectly.

So this machine is very cool. I actually haven't seen this before. It's a machine for making self-fabric collar. If you look at the t-shirt I'm wearing right now, my t-shirt is composed of one fabric that's a jersey and another fabric over here that's a rib. They're two different fabrics. It's not the same. In this case, what she's doing over here is she's taking this piece of jersey and she's creating this roll of self-fabric. So over here they have that self-fabric we were talking about, and it's unspooling slowly. And notice how there's multiple metal pins here to control the speed of the fabric and control the consistency so that it stays flat, it stays aligned. They just did the collar very conveniently. So that's the exact application of it, right? The collar is the same fabric as the body.
