Abstract

Starting with stiff, flat wafers in laminar form, ready-made, the wafers are laid unitarily on trays (3) fitted on a conveyor belt (2), which causes them to pass through a tunnel (5) wherein they are subjected to heating until softened, after which the trays (3), of a three-part structure, have their side segments swivel with respect to their central segment reshaping the respective pieces of wafer into a fluted form having a U-shaped section, assisted in this wafer-shaping process by a pressing mechanism (14) equipped with a plurality of tampers (17) which act sequentially and unitarily on the respective trays, helping in the cooling of the wafers for these to retain their reshaped form in a stable manner, there being mounted immediately thereafter and on the conveyor belt (2) itself an ice-cream feeder mechanism (18), the ice cream filling the fluted bodies defined by the wafers after being reshaped.

Claims4

Dependent claims

Machine for manufacturing ices comprising:

a conveyor belt having a loading area fitted with a plurality of trays for housing flat and stiff pieces of wafer
a tunnel oven mounted on said conveyor belt beyond said loading area of said conveyor belt for softening said flat and stiff pieces of wafer housed within said trays,
a shaping mechanism installed on said conveyor belt in a shaping area after an exit of said tunnel oven in which marginal parts of each tray are folded in an upward direction transforming the wafer housed within said tray into a fluted form, having a U-shaped section with rounded vertices, assisting in the shaping of said pieces of wafer (10)
a pressing mechanism fitted with a plurality of tampers for assisting in the shaping of wafers housed within said trays, which pressing mechanism acts on the trays, and more specifically on an upper face of the wafers located inside said trays,
a feeder mechanism located on said conveyor belt beyond said pressing mechanism for filling said fluted form of said wafer with ice cream.
