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 drive the rollers, but I think chains are sometimes used as
well.
There are a lot of wire processing facilities around me and a lot of
bolt plants.

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.

Subject: [Emc-users] OT: Wire feeder on screw forging machine
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 the
wire has reached the stop.
Is there any common and simple mechanism for this purpose? I've never
really worked with machines like this so I'm curious about what the
simplest solution could be. I can imagine several ways to do it but I don't
want to re invent the wheel.
Thanks as always!
Leonardo.
