Abstract: An apparatus is disclosed for comminuting gypsum board and winding elongate bendable members. The apparatus includes a support structure and a comminuting mechanism, including a housing mounted to the support structure. The housing has an intake portion for receiving gypsum board to be comminuted, an outlet portion for discharging comminuted material, and one or more blades rotably mounted in the housing. There is a winding mechanism that includes a winding shaft axially rotatably mounted to the support structure. The winding shaft has a slot disposed therein for receiving an elongate bendable member to be wound. There is a holder device mounted to the support structure and spaced apart from the winding shaft for accommodating the member to be wound at a location spaced apart from the portion of the member received by the slot in the winding shaft.
