When the spray nozzle 26a sprays water in the form of spray onto the belt surface and each core material C placed on the belt 5a is transferred onto the belt 6a of the next belt conveyor 6, the core material C is transferred onto the belt 5a. So that it can be easily peeled off.

Similarly, on the upper surface of the belt 6a on the inlet side of the belt conveyor 6, a spray nozzle 26b is arranged toward the upper surface of the belt 6a immediately before the next mounting step 2.
Spraying water is sprayed from the spray nozzles 26b onto the core cloths C on the belt conveyor 6, so that the flat melon-side cloths placed on the core cloths C can be reliably attached.

Although the present invention has been described above, it is needless to say that the present invention is not limited to the embodiments and various other modifications can be made without departing from the essence thereof. . For example, in the present embodiment, the opening / closing operation of the shutter, which is the supporting member, employs a mechanism that separates the joints by horizontal movement, but employs a mechanism that swings the joints downward to open them. It is also possible. Further, the mechanism for opening and closing the shutters 13a and 13b adopts the combination of the link lever described above, but the same movement can be achieved by adopting the combination of the rack and pinion or the chain sprocket instead. Can be obtained. Further, in the specification, the term melon bread is used, but this is an exemplification, and means a product substantially composed of a core material and an outer material covering the core material.
