WoodLeather Report post Posted January 28, 2022 Hello everyone, I have the possibility to purchase an Adler 205.64 (extra-heavy duty / dual-feed bottom+needle) at a reasonable price and was wondering how much better a triple feed machine is. Many thanks for your feedback Quote Share this post Link to post Share on other sites
DrmCa Report post Posted January 28, 2022 Better for what kind of work? It's a great machine for heavy leather. One of the best. But it has its limits like any other. Quote Share this post Link to post Share on other sites
Wizcrafts Report post Posted January 28, 2022 Needle feed machines work best if the material is slippery on top. Otherwise, it will drag against the presser foot. The amount of drag depends on how much pressure is applied to the foot. That pressure varies with the thickness and density of the material being sewn as well as the sizes of the top and bottom thread and the needle. The lockstitch "knots" may be very tight inside the holes and can fight against the pressure spring and actually cause the leather to lift with the needle on the way up. This leads to skipped stitches. If you are buying this machine to sew veg-tan leather, you'll probably need to crank down the pressure screw to keep the leather from lifting with the ascending needle and thread. The more pressure you need to hold down the leather, the more drag the foot has against the top layer. The foot will fight against the feed.This is not a good situation. OTOH, if you are buying the machine to sew heavy cloth or synthetics, like buffing wheels, smooth Kydex, bioplastics, or webbing, it should be a good match.
