## Abstract

The complementary parts of food products destined to be coupled together are located on the frontal surfaces of half-moulds travelling on two different loop conveyor lines. The first conveyor line extends, at least partially, above the second, so to be included within the surface area occupied by the second line itself. Spatial occupation is further reduced since, downstream to the coupling station, the coupled half-moulds travel with the same spacing step that they had before coupling, with additional advantages in terms of energy absorption and advancing velocity in a successive thermal conditioning station, such as a refrigerating tunnel. One of the half-moulds can be removed upstream to the thermal conditioning station, resulting in an additional reduction in energy absorption since needless subjecting of the half-mould to the thermal cycle to which the products are subjected is avoided.

## Claims

### Claim 1

A method for the production of food products comprising a wafer shell that contains a creamy filling mass and is formed by complementary parts coupled together, the method comprising:
locating wafer sheets having a matrix of said complementary parts in a first and second half-moulds, said first and second half-moulds having corresponding frontal surfaces with cavities configured to house said complementary parts;
advancing said first and second half-mould on first and second conveyor lines respectively;
separating said complimentary parts housed within said cavities of said first and second half-moulds from said wafer sheets;
coupling said complementary parts in correspondence with a coupling station inverting at least one between said first and second mould so to bring said first and second half-mould into a configuration in which said frontal surfaces of said half-moulds are reciprocally facing;
after the coupling of said complementary parts, removing one of said first and second half-moulds so that the reciprocally coupled complementary parts are left on the other of said first and second half-moulds; and
after the removal of the one of said first and second half-moulds, thermally conditioning the reciprocally coupled complementary parts left on the other of said first and second half-moulds;
wherein said first and second conveyor lines have a general loop path with corresponding sections of the loop trajectories mutually facing in correspondence with said coupling station, and said at least one between said first and second half-mould is inverted around an axis transverse to the advancing direction of the corresponding conveyor line.

### Claim 2 (depends on 1)

The method of claim 1, wherein said first conveyor line brings the corresponding complementary parts above the complementary parts of said second conveyor line.

### Claim 3 (depends on 2)

The method of claim 2, wherein the inverting at least one between said first and second mould comprises, before coupling said complementary parts, rotating said first half-mould so as to turn the frontal surface of the first half-mould downward.

### Claim 4 (depends on 3)

The method of claim 3, wherein said coupling of said complementary parts comprises said first and second half-moulds approaching each other according to a relative linear movement.

### Claim 5 (depends on 1)

The method of claim 1, wherein the coupling of said complementary parts comprises releasing elements acting on the complementary parts of one of said first and second half-moulds to free the complimentary parts from the corresponding half-mould.

### Claim 6 (depends on 1)

The method of claim 1, wherein said complementary parts are on said first and second half-moulds.

### Claim 7 (depends on 1)

The method of claim 1, further comprising, before coupling said complimentary parts, dosing an ingredient inside said complementary parts.

### Claim 8

Equipment for the production of food products comprising a wafer shell that contains a creamy filling mass and is formed by complementary parts coupled together, the equipment comprising:
first and second half-moulds configured to receive wafer sheets having a matrix of said complimentary parts, said first and second half-moulds having corresponding frontal surfaces with cavities configured to receive said complementary parts;
a first and second conveyor line configured to transport the first and second half-moulds respectively, said first and second conveyor lines being coextensive for at least a corresponding portion;
