In an apparatus for making a rolled wafer cone from a baked flat wafer blank made from a sugar-containing wafer dough, the baked wafer blank is rolled to form a wafer cone in a winding mold while the wafer blank is still in a soft, deformable state after the baking operation. Thereafter the rolled wafer cone is permitted to harden. In order to ensure the production of wafer cones having consistently exactly the same shape, it is proposed that the wafer cone which is unrestrained at least in part is shortened in the winding mold to a predetermined length while the wafer cone is adapted to be plastically deformed. For this purpose the rolled wafer cone disposed in the winding mold is subjected to a plastic deformation only at one end or only at both ends. The apparatus includes means of winding devices, which are mounted on a rotary frame and each of which comprises a conical winding core, which is secured to a winding shaft that is displaceable relative to the rotary frame to move the conical winding into and out of the winding mold. Each winding device is provided with at least one sizing device, which is associated with the rim of the wafer cone and comprises at least one pressure-applying finger, which is adapted to be introduced between the winding mold and the winding core.

The spacing between laterally closely juxtaposed, parallel, rectilinear rows of wafers filled with a sticky composition is increased by advancing the rows of wafers on a supporting surface in a first direction to entrance portions of guiding passages extending at a second direction angularly diverging from the first direction at a bend. The entrance portions are staggered in the direction of advancement. A rotary disc is associated with the entrance portion of each guiding passage and has an upper portion protruding through a slot in the supporting surface and constituting a guiding face facing the guiding passage, and a shaft is arranged below the supporting surface and rotatably supports the rotary disc. An oiling and/or cleaning device is associated with each rotary disc below the supporting surface for oiling and/or cleaning the guiding face of the rotary disc.

In a process of making a rolled wafer cone from a baked flat wafer blank made from a sugar-containing wafer dough, the baked wafer blank is rolled to form a wafer cone in a winding mold while the wafer blank is still in a soft, deformable state after the baking operation. Thereafter the rolled wafer cone is permitted to harden. In order to ensure the production of wafer cones having consistently exactly the same shape, it is proposed that the wafer cone which is unrestrained at least in part is shortened in the winding mold to a predetermined length while the wafer cone is adapted to be plastically deformed. For this purpose the rolled wafer cone disposed in the winding mold is subjected to a plastic deformation only at one end or only at both ends. The process can be carried out by means of winding devices, which are mounted on a rotary frame and each of which comprises a conical winding core, which is secured to a winding shaft that is displaceable relative to the rotary frame to move the conical winding into and out of the winding mold. In that apparatus each winding device is provided with at least one sizing device, which is associated with the rim of the wafer cone and comprises at least one pressure-applying finger, which is adapted to be introduced between the winding mold and the winding core.

A spreading head is provided for a wafer sheet coating machine, which comprises a wafer sheet conveyor, which is optionally adapted to be lowered. The spreading head comprises a rotating spreading roller and a sizing device, which cooperates with said spreading roller to control the thickness of a layer of a spreadable composition as it is transferred by said spreading roller. The spreading roller and the sizing device define a lower boundary of a reservoir, which is adapted to hold said spreadable composition and which is laterally defined by platelike elements. To prevent an escape of spreadable composition from the reservoir along the end faces of the spreading roller, it is proposed to provide at least on each end face of the spreading roller a lateral covering, which extends from the reservoir for the spreadable composition along the periphery of the end face of the spreading roller continuously at least as far as to the point where the layer of the composition transferred is removed from the spreading roller. Said covering may be integral with the adjacent platelike element.

Process and apparatus for continuously making an endless wafer laminate which has a uniform width and consists of individual wafer sheet layers and intervening cream layers. In order to increase the production rate of such wafer laminate while maintaining a high quality, the invention teaches that each edge of the wafer sheets for the lowermost wafer sheet layer is registered and the deposition of the wafer sheets for the remaining wafer sheet layers is controlled by the succession of said wafer sheet edges. The butt joints of the wafer sheets in the individual wafer sheet layers are offset relative to each other in the direction of conveyance or are arranged exactly in register. For registering the wafer sheet edges, the edges of consecutive wafer sheets are displaced or pivotally moved relative to each other or pulled apart to form a gap. Each wafer sheet for the additional wafer sheet layers is moved to a waiting position in the wafer sheet applicator, which succeeds the coating head for applying a cream layer, and in dependence on the succession of the wafer sheet edges of the lowermost wafer sheet layer is applied to the adjacent cream layer and is then forced against the same. The resulting wafer laminate is used as an intermediate product for making small wafer slices.

In a process in which cover sheets and/or coated wafer sheets are joined to form filled wafer blocks, each coated wafer sheet and, if desired, each cover sheet is moved in a stacking location from a lower position to an overlying upper position, the coated upper surface of each coated wafer sheet is joined to the underside of the cover sheet which is in the upper position and which, if desired, has previously been raised to the upper position, or to the underside of the coated wafer sheet which has previously been raised to the upper position, and each complete wafer block consisting of at least two sheets is moved from said upper position out of said stacking location. To increase the production rate, it is proposed that the successive coated wafer sheets for each wafer block or successive coated wafer sheets and cover sheets disposed between successive coated wafer sheets are successively and continuously fed one by one to the lower position in the stacking location, and at least part of the movement of each of said sheets to said lower position is performed while the next preceding sheet is being raised. It is also proposed to carry out the process by means of two helical conveyors, which have parallel axes of rotation, which are inclined from a normal on the plane of conveyance of the wafer sheet feeder and each of which has a lower convolution, an upper convolution, and an inclined step joining said upper and lower convolutions.

Process and apparatus for producing filled wafer blocks

Apparatus is provided which is used in combination with a machine for coating wafer sheets and serves to form wafer blocks built up in a downward direction. It is desired for avoiding damage to very large wafer sheets as they are assembled to form wafer blocks by means of helical conveyors, which rotate in mutually opposite senses about parallel axes and which move each wafer sheet into engagement with a stop and raise the wafer sheet from a first level to a second, higher level. This is accomplished in that each helical conveyor is provided with at least two helical wire flights, which extend parallel to each other around the axis of rotation of the conveyor. The helical flights of all helical conveyors define a common imaginary surface and support the wafer sheets on said surface. The novel apparatus as well as the wafer sheet coating machine is used in the industrial production of large wafer blocks, which constitute a starting product for the industrial manufacture of slices of wafer blocks.

Apparatus for making wafer blocks

Apparatus for conditioning wafers, such as wafer sheets, flat wafers, low hollow wafers and the like comprises an insulated conditioning chamber, which is closed except for a feed opening and a discharge opening, a revolving conveyor, which extends in the conditioning chamber adjacent to the feed opening and the discharge opening and is provided with successive compartments for receiving wafers, and air-guiding passages, which extend along the path of the compartments and are connected to an air-conditioning plant, which is preferably disposed outside the conditioning chamber. The clearance between the supporting elements which have been moved or swung toward each other is substantially one to 5 times, preferably 1.1 to two times, the wall thickness of a flat wafer or once to twice the height of a low hollow wafer. At least one of the two supporting elements rises above the received wafer at least with a projecting portion.
