Baking hand shmura matzahs involves placing the matzahs in an oven using long wooden poles. Out of concern that some dough may be stuck on to the pole the poles are sanded down after use.
Some avoid the whole issue of stuck dough and cover the poles with paper using masking tape as the adhesive - a common practice in matzah chaburos. Since the matzah comes into contact with the masking tape it is necessary to ensure that the tape adhesive is kosher for pesach as starch based adhesives sourced from chametz may be used. Google "starch based adhesive" for more information.
