Some proteins are completely synthesized by free ribosome particles in the cytosol before entering the ER lumen. This mechanism is called post-translational protein translocation.
After translation, the cytosolic chaperones immediately bind to the polypeptide chain to prevent it from folding prematurely.

Thanks this tells me absolutely nothing about post translational translocation
