摘要:
Process and corresponding apparatus for wrapping a product in a wrapper of sheet material, adhering to the surface of the product, the process comprising the steps of: providing a first and a second sheet of wrapping material, shaping said first sheet according to a cup-shaped configuration comprising a bottom portion substantially complementary to a bottom portion of the surface of the product, a tubular portion which extends above the top of the product when inserted in said so-shaped sheet and defining a mouth adapted for the introduction of the product and an annular flange terminal portion surrounding said mouth, introducing the product in said first shaped sheet, and connecting said second sheet to said annular flange so as to form a closed wrapper around said product. Following the introduction of the product and prior to connection of said second sheet with said annular flange, it includes the operation to make a bottleneck of said tubular portion of said first sheet in its region immediately above the top of the product, exerting on said annular flange a pressure suitable to bind the edges of flange or to limit its radial movement, so as to cause the adhesion of said tubular wall to a substantial portion of the top surface of the product.

摘要:
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.
