I wonder how industrial machines get around the bobbin capacity issue? A

pre-loaded bobbins?

No, typically they use either HUGE bobbins (compared to domestic sewing
machine bobbins),

I assume they sew more slowly, needing to make a bigger loop of the
needle thread and get it round a bigger bobbin

No, most industrial mchines sew at several thousand stitches per inch as opposed to the low hundreds of most domestic machines. Some of the newer larger embroidery machines (like that amazing Bernina I'll buy when I win the lottery!) have a bigger bobbin and sew at 1100 SPM.

or two cones of thread, one of which is fed in under
the machine bed through what would be the bobbin area on my machines. :).


with a continuous feed (like a serger) the machine can only do
chainstitch, as far as I can tell.

Yes, those ones usually do a chainstitch. It works until a thread pulls loose!
