The twine tubes have a breakaway device between the drive mechanism and the tubes. Is yours tripped?
Its not my baler its my boss's baler and i told him i would ask online if anyone could answer my question. I'm not sure what the breakaway device is. Does the breakaway device when tripped allow the gear to spin then stop when it makes one cylcle. I'm not very good at trying to explain this. Sorry.

Yes, if the breakaway is tripped, the mechanism will cycle but the tubes won't. Tell your boss to dig out his op manual, or buy one. The tubes can be re-set by hand, but it takes a fair amount of effort. It's best accomplished when the gears are stopped about halfway back to the home position.

never a a 640 baler
On other balers there is a shear bolt on the eccentric to the right of the knotters if the needles don't move it will not reset and the baler will just keep on tying Its normally a 5/16 grade 5 bolt

The 640 was among the first series of NH belt style round balers. Models 630/640/650/660 built from 1/1993 through 9/1995.
