Oftentimes I have seen just a couple of grooved pinch rolls used - aka
like a mig welder wire feeder. It really depends on how much drive
force you need. If you pinch the wire too hard it will deform and
extend. So for more drive force, use more drive rollers. You can
use gears to
Check out "wire straightening machines" on youtube. You'll
see a bunch of machines with pretty similar wire feeding
methods. Some of those may give you more ideas than
what you see on the screw heading machine.

There are quite a few videos on youTube showing simple wire feed mechanisms
using an Arduino as a controller. Searching for 'wire cutter Arduino' gives a
list. You may get some good ideas there, for simple feeding mechanisms. Whether
you need an Arduino is another matter, but the mechanics are
Hello to all.
I'm trying to figure out how to design the simplest possible wire feeder
like the one on this video: https://youtu.be/_pjbwFM1LM4?t=28s
As you can see the wire comes to a stop (a simple bolt with a nut) so I
suppose the feeding mechanism has some sort of slipping capability once
