If what you want is to have the least amount of spring back possible then let the glue up sit for 24hrs before taking it out of the clamps. Once out of the clamps, find a way to hold it roughly in position for another 24hrs with air flow getting to all sides. Urea glue does not fully cure when wrapped in plastic, hence the second 24hrs to get the residual moisture out. Bent laminations will not hold if you remove the clamps when the glue is rubbery. That is only good for flat unstressed work, like veneering.
