Pasta machine rolls dough wider than machine I have a (admittedly rather cheap) pasta roller that I try to use fairly regularly. The issue is that when I am rolling it out,the dough keeps getting wider, not just longer, beyond the size of the rollers, and then getting all mangled at the edges. It also has a hard time feeding in straight.  Every video I watch on pasta making doesn't seem to show this, so it is just some trick they aren't mentioning, the cheap machine, or what?
You might be rolling the dough too thinly, too soon. Start by feeding a somewhat flattened 'disk' of dough through the pasta machine at its widest setting. Change the setting by at most 1 for each subsequent pass.
You might also benefit from 'laminating' the dough: after the first pass, fold the dough in thirds, turn it 90 degrees and pass it through the machine again. Here is a picture demonstrating the procedure from the Serious Eats &quot;Science of the Best Fresh Pasta&quot; guide.
