A wrapping group for wrapping products, in containment bands, including a support structure which defines an advancing plane and with which are associated a first conveyor for conveying a plurality of products one after the other and spaced apart from each other, along the advancing plane and along an advancing direction. Each editorial product includes a book and/or a packet of sheets or of sheeted products stacked on each other. A feeding device feeds a plurality of containment bands laid in length one after the other and spaced apart from each other along a plane substantially transversal or orthogonal to the advancing direction and along a feeding direction substantially transversal or orthogonal to the advancing plane of the products.

An apparatus for the preparation of comestible-containing sandwich products comprises a sandwich product assembly station and corresponding means for the fabrication and assembly of a sandwich product in the vertical direction. The apparatus includes an extruder nozzle, wafer trays and corresponding components for the location of wafers on opposite sides of the extruded product, an indexing wheel for receiving the assembled sandwich product, and sandwich transporting means for moving the sandwich to a wrapping assembly and from there to a discharge end, wherein all of the components of the apparatus are mounted in cantilevered fashion on a vertical support or base member. Each element is powered individually by a servo motor or actuator and controlled by a controller allowing the variability of throughput for each station.

One embodiment of the present invention includes an apparatus for securing a wrapping material around an item, such as a baled agricultural item, the apparatus including a main plate and at least one projection, the projection including a heating element and a height adjustment mechanism, wherein the height adjustment mechanism controls a force applied to the wrapping material by the projection and provides a force for moving the projection.

Described is a machine for wrapping groups (1) of products in a roll, comprising: a packaging unit (2) positioned above a feed channel (3); a transfer element (5) configured for feeding, in a feed direction (V5), to the packaging unit (2) the groups (1) of products in a roll with a corresponding sheet of wrapping material (6); feed and positioning units (8) configured for feeding the sheet (6) of wrapping material inside the vertical channel (3), in a direction (T6) transversal to the direction (V5) for feeding the group (1) of products; the machine also comprises means (9) for controlled retaining and unwinding of the sheet (6) of wrapping material positioned along the vertical feed channel (3); a first movement unit (10) connected to the controlled retaining and unwinding means (9) and configured to move the controlled retaining and unwinding means (9) from a position of free passage of the sheet (6) of wrapping material to a position for bilateral retaining of the sheet (6) of wrapping material positioned in the channel (3); a second movement unit (11) connected to the controlled retaining and unwinding means (9) and configured to move the controlled retaining and unwinding means (9), located in the retaining position, so as to unwind the sheet (6) of wrapping material in a controlled manner and at the movement of the transfer element (5) from the first lower operating position to a second upper operating position.

Packaging machine for packaging paper rolls, including an operating group forming packages, with an entrance station for the rolls and the packaging sheets, and an output station for the packaged rolls; an elevator; a structure on which the operating group is mounted; a plane on which a folder and a counter-folder are formed for folding the packaging sheets under the rolls; a conveyor for moving the packages being formed above said plane; means for welding the packaging sheets; a welding bar for welding the packaging sheets under the rolls. The welding bar is configured to come out through an opening made on the counter-folder and reposition itself below the latter. The carriages are controlled independently of each other.
