1. Apparatus for making a rolled wafer cone having an annular cone rim and a closed cone tip, which comprises(a) wafer-baking oven for baking a plastically deformable, flat wafer blank of a sugar-containing dough, the blank having a circumferentially extending rim and the oven having a delivery station for the baked flat wafer blank, and(b) a rolling apparatus having a blank-receiving station facing the oven delivery station for receiving the baked flat wafer blank to be rolled into the wafer cone and a rolling apparatus delivery station for delivering the rolled wafer cone, the rolling apparatus comprising:

  • (1) a rotary frame rotatable about an axis and having a circumference surrounding the axis, and(2) a plurality of winding devices spaced from each other along the circumference of the frame and mounted thereon for rotation therewith between the blank-receiving and delivery stations of the rolling apparatus, each winding device comprising;

    (i) a winding mold having a conical inside surface defining a conical cavity having a longitudinal axis, a wide open end and a narrow end opposite thereto, the winding mold having a slot for introducing the baked flat wafer blank into the conical cavity,(ii) a rotatable winding shaft extending coaxially with the longitudinal winding mold cavity axis and parallel to the rotary frame axis, the winding shaft being axially displaceable and having an end facing the winding mold,(iii) a conical winding core secured to the winding shaft end for rotation therwith and movable into the conical winding mold cavity upon axial displacement of the winding shaft whereby the conical inside surfaces of the winding mold and the conical winding core define a gap receiving the plastically deformable, flat baked wafer blank through the slot in the winding mold for rolling the wafer blank into the wafer cone upon rotation of the winding shaft and winding core secured thereto while the rim of the blank remains unrestrained and a portion of the unrestrained blank rim forms the cone rim, and(iv) a sizing device for plastically deforming the cone rim of the rolled wafer cone until it has an accurately defined annular rim and an accurately defined length extending between the cone rim and cone tip.
