A solar panel cutting unit includes a frame, a panel transporting mechanism at the frame to lower the solar panel in a vertical direction, first guide roller units below the panel transporting mechanism to guide and lower the solar panel, a first wire cutting mechanism including first support rollers and a first cutting wire connecting the first support rollers to each other and extending in the same direction as the adhesion lines such that the first wire cutting mechanism separates one of the thin layers from the solar panel, and a second wire cutting mechanism below the first wire cutting mechanism and including second support rollers and a second cutting wire connecting the second support rollers to each other and moving in parallel to the first cutting wire such that the second wire cutting mechanism separates another of the thin layers from the solar panel.

An apparatus for manufacturing panels made of foamed plastic material includes a supporting framework for a device for feeding a plate-like element to be cut to at least one cutting station and a device for unloading the plate-like element cut into panels from the cutting station. The cutting station includes a supporting structure for at least one cutting wire that forms, along its own extension, a cutting portion designed to contact the plate-like element to be cut, a component for the relative motion of the cutting portion with respect to the plate-like element to be cut, there being also, upstream of each cutting station, an incision station having at least one first incision blade adapted to provide, at at least one face of the plate-like element to be cut, a respective incision at the region designed to be contacted by the cutting portion of the cutting wire.

A bread slicer includes an input compartment for a loaf of bread to be sliced and an output compartment for the sliced loaf. Blades for slicing the loaf are arranged substantially parallel to one another between the compartments. A thrust means extends at least on the side of the input compartment and permits exertion of a push force on the loaf while the latter is moving through the set of blades by clamping the loaf between the thrust means and the base of the input compartment. The base and the thrust means define a passage in the input compartment for the loaf. The thrust means presents a guiding plate with parallel recesses extending next to each other over the width of the passage. A mobile pusher device allows exertion of a pushing force on the loaf to move the loaf along the passage and through the set of blades.

A topping sheet forming method includes: feeding a textile original fabric, obtained by weaving longitudinally aligned tire cords into a cord fabric by use of weft yarns; cutting off the weft yarns at a predetermined widthwise position to divide the textile original fabric into a plurality of narrow textile original fabrics; and topping at least one surface of the narrow textile original fabric with unvulcanized rubber.

An apparatus for detecting the breakage of at least one cutting element disposed in a guide includes at least one sliding piece which is linearly displaceable relative to the guide and which can be connected to the cutting element for holding the cutting element. A force applying element is provided to produce a force on the sliding piece so that if the cutting element breaks, the sliding piece is displaced relative to the guide. A sensor detects such a displacement of the sliding piece relative to the guide. A system having the detection device is also provided.
