A few notes re my experience with industrial sewing machines:
Cumbersome, noisy, energy intensive clutch motors on industrial machines have been going away for years, being replaced by compact lightweight servo motors.
Juki is the brand you see in most of the cottage shops, except zPacks lol.
Basic industrial feed mechanisms are roughly divided into three categories. Zig-zag function is rare and usually takes a dedicated machine.
1. Single needle lockstitch. Simple and inexpensive. For everything from 10d to webbing. Juki 8700 is ubiquitous here.
2. Needle feed. Complex dual feed makes puckering and dissimilar feed rates a non issue. If you can afford one of these do it. 10d to webbing. Juki 5410.
3. Walking foot. Brutish machines specialized for leather, harnesses, etc. Used by pack shops for the heaviest of tasks. A skilled operator can do finer work too with a marketable look. Not suitable for quilts, tarps, garments. Juki 1541.
