To roll out pastry is to flatten it with a heavy cylinder. Away from you, a quarter turn, and again.
The technique matters, since turning the dough rather than the pin keeps it even and stops it sticking. The rolling pin is the tool. There is a completely separate business sense that is now much commoner, since rolling out a product or a scheme means introducing it in stages across a whole area, and the noun rollout is standard. Rolling out the red carpet means an elaborate welcome.
