Wood laths work (i.e. distort) by losing or gaining moisture.
Boatbuilders prepare laths for significant bends by
1) soaking
2) steaming
3) soaking in water with ammonia added.
 - in order of aggressiveness
 (This last method  is reputed to produce
spaghetti until the wood dries again.)

Drying a lath in a cool environment on a straight former
can do the job.
