1. A machine for the production of tubular casings of alimentary dough by rolling up pieces of sheet dough around a cylindrical support core, said machine comprising:

  • a support structure;

    a continuous belt conveyor mounted on the support structure and having a receiving end and a discharge end,feed means for feeding a continuous sheet of dough to the receiving end of said conveyor;

    a punching device disposed above said conveyor downstream of the feed means and provided with shaped punches arranged to cut said continuous sheet of dough in synchronism with the advance of said conveyor so as to cut out successively from the said continuous sheet a series of spaced-apart pieces or groups of adjacent pieces of dough,recovery means disposed along said conveyor downstream of said punching device and arranged to take up from the conveyor that part of the dough sheet remaining after the cutting of the said pieces;

    a dispensing unit arranged above said conveyor downstream of the said recovery means and comprising a receptacle for containing cylindrical support cores, and a withdrawal member for taking out support cores from the receptacle and depositing them on said conveyor such that each said core is disposed transversely between two successive said pieces or groups of pieces of dough,a rolling-up unit disposed transversely adjacent the discharge end of said conveyor and comprising an endless web extending upwardly with respect to the conveyor, the said endless web being supported adjacent its upper end from said support structure for back and forth movement and having a rolling-up pass which, in use, has a direction of advance from its lower end towards its upper end away from said conveyor, and actuator means for effecting in synchronism with the operation of said withdrawal member of the dispensing unit, back and forth movement of the said endless web between a substantially-vertical rolling-up position and an inclined discharge position, said endless web being operative when in its rolling-up position to entrain in rotation a said support core fed thereto by said conveyor and to cause the rolling-up thereon of a respective piece or group of pieces of dough, andcollecting means for receiving the said support cores with respective pieces or groups of pieces of dough rolled up thereon from the discharge end of said conveyor when the said endless web of the rolling-up unit is moved into its discharge position.
