I’m not Tom but I use a sheeter for my dough. When this happens to me, it’s one of two things: Either my sheeter settings are set a little too thin trying to flatten the dough ball too quickly thus tearing it a little, or I’m not using enough flour on the dough ball and it is sticking to the rollers as it’s flattening out. Make sure your rollers are clean and there’s no hard, dry dough stuck to the them.
