Abstract: A machine is configured to make a food roll, wherein a strip of dough is spirally wrapped around a food product elongated along an axis between two ends. The machine comprises a feed means for conveying a plurality of strips of dough that are spaced apart from each other along a forming path and a wrapping station for wrapping each strip of dough around a food product. The wrapping station comprises a positioning area, which is configured to position the strip of dough obliquely with respect to the axis of the food product, and a rolling area for the strip of dough, which is configured to wrap the strip of dough spirally around a food product starting from one of the ends of the food product. The rolling area comprises two spindles that are rotatable about an axis of rotation and each one having an attachment portion for retaining a food product at the ends thereof.

Abstract: Lighting device and method to make it. The device comprises a light source (11) including a positive electrode (14) and a negative electrode (13) between which a luminescent layer (16, 17) is located. On the outer side of the multi-layer structure there is a substrate (20) which diffuses the light generated by the luminescent layer (16, 17). A lenticular optical element (21) is associated with a face of the substrate (20) and is obtained by means of molding in a single piece in the substrate (20). The optical element (21) consists of micro-lenses (22) each one cooperating with a relative point of light emission (19) to direct and shape the relative ray of light emitted.
