I’m wondering what the right professional machines to use to do flat felled seams on both sides of a tube tent. I’m looking at these machines (link below), but I don’t understand how you can get 8 feet of ripstop nylon behind the feeder.
Thank you.

Any machine will do fine
Sew the two pieces together, then spread out, fold over twice, and sew through the fold. Â Or sew an extra row of stitches just to make sure. Â So you do three rows of stitches. Â With the professional machine you only need one pass through the machine so it takes less time.

Sep 28, 2016 at 11:03 am #3428459Just wondering; have you called them? They probably know their machines better than we do. I’d also ask how a machine made for denim will handle light slippery synthetics.
Sep 28, 2016 at 6:01 pm #3428523You need to be aware that the link is to chain stitch machines, not lock stitch which is what I expect you actually want.
Oct 1, 2016 at 12:10 am #3428785You’re right. I havn’t been able to find an off the arm, double needle, lockstich (301). They are all chain stitchers (401) whether they are light duty or otherwise. Does anybody know how the big guys make their flat felled seams? Do they use a chain stitch?
Oct 1, 2016 at 9:01 pm #3428890For most gear other than some clothing you would only use lock stitch. Â The issue with chain stitch is that if a thread breaks then the whole seam can unravel. Â For something like a tube tent you do not need an off the arm machine, a regular flat bed machine is fine. Â It may be easier if you have a longer arm than normal but the size of the opening in a tube tent won’t cause any problems that an experienced industrial machinist would have to wrestle with.
