Pasta names change from village to village. This was filmed in Lavello, Basilicata; Elisabetta and Lucia make maccarunata (the spelling is theirs) which is also known as troccoli elsewhere.
Pasta rolling pins like Elizabetta’s can be found online: in the States, Haydon Flour Mills sell a lovely walnut wood one, while Shop Mancini sell very cheap beech ones. In the UK take a look at Italian Cookshop who sell them for £5.
