  • Patent number: 6254916
    Abstract: Edible wafer rolls are produced by baking an endless plastically deformable wafer strip from a flowable sugar containing wafer dough, directing the wafer strip continuously from the hot endless revolving baking surface onto a continuously rotating mandrel juxtaposed with a counter rotating winding roller, grasping the leading portion of the strip and pulling it around the mandrel toward a following wafer strip portion. The wafer is wound in helically overlapping turns to form the hollow wafer body which is cutting into wafer rolls of a predetermined length.

  • Patent number: 6227103
    Abstract: A machine for making cones from baked wafers utilizes roll-up mechanism in the form of a roll-up mandrel and a roll-up form. A multiplicity of such mechanisms is carried by a chain along an endless path. Each roll-up mechanism can have a frame on which the roll-up mandrel and roll-up form is mounted.

  • Patent number: 6102190
    Abstract: Device for intermittently transporting objects, in particular coated wafer sheets or filled wafer blocks. At least one stop (5) that can be lowered below a transport plane is mounted downstream of a device (2) that pushes the objects (1) forward in the transport plane. The stop (5) has a bearing surface which is associated to the front face of the objects (1) and can be moved back and forth between an upper position in which it projects upwards with its bearing surface above the transport plane and a lower position in which it is lowered below the transport plane. At least one scraper (12, 13) associated to the bearing surface is arranged along the path of displacement of the bearing surface. The stop (5) consists of a moulded body (7) that be moved up and down and of a bearing surface that can be moved in relation to the moulded body (7) between a work position associated to the front face of the objects (1) and a rest position removed therefrom.

  • Patent number: 4669603
    Abstract: When it is desired to single consecutive filled wafer slices, which are advanced with abutting trailing and leading faces, respectively, so that the singled wafer slices are ultimately spaced apart, a separation between consecutive wafer slices is to be effected in time even if the wafer slices are filled with cream so that their filling layers will strongly adhere to each other. This can be ensured in that a transfer device is provided between a feeding conveyor for advancing consecutive wafer slices abutting at their trailing and leading faces, respectively, and a delivering conveyor for advancing the rows of wafer slices on a delivery plane, which is vertically spaced from the feeding plane, on which the wafer slices are advanced by the feeding conveyor, and the transfer device pulls each leading wafer slice from the next succeeding wafer slice and moves the pulled-off wafer slice to the delivery plane.
