Machine and method for folding a sheet of packaging material around a corresponding article to create a package

[Abstracts] The present invention provides a packaging machine (1) and method for producing a package (2) by folding a sheet of packaging material (6) around a corresponding article (3); the package delivery device (21) is conveyed and folded along the packaging path. A head (22) containing a package (2) and having an electrically heated activation member (35, 36, 37) for providing heat to a portion of the package (2); the folding head (22) also has a movable magnetic A core (40), which has a coil (41) electrically connected to the activation member (35, 36, 37), is disposed toward and is magnetically coupled toward a fixed core (38) disposed parallel to the packaging path. In use, a current (C1) is supplied to the coil (39) coupled to the fixed core to induce a corresponding current through the coil (41) of the movable core (40).

[Sovereign Items] 1. A packaging machine for producing a package (2) by folding a sheet of packaging material (6) around a corresponding article (3); said packaging machine (1) comprising a delivery device (21) The packaging transport device has at least one seat (22) which is fed along the packaging path into the package (2) and has at least one electrically heatable activation element (35, 36, 37) for the packaging ( A portion of 2) provides heat; the packaging machine (1) is characterized by comprising a plurality of fixed first cores (38) each having a respective first coil (39), and its position is along A portion of the packaging path is parallel to the transport device (21); the seat portion (22) includes a corresponding movable second magnetic core (40) with the activation member (35, 36, 37) The second coil (41) is electrically connected, and its position is opposite to and magnetically coupled with the fixed first magnetic core (38); and a power supply device (42), which provides the first coil with a first in use A current (C1) induces a corresponding second current (C2) flowing through the second coil (41).
