Abstract: The machine comprises a main carousel including a horizontal axis having seats which are angularly equidistant and open outwardly and including at the front a gripper and at the rear a folding device. Each seat passes first adjustable means with the gripper open to supply the gripper with a packaging sheet arranged on the seat, and cooperating with a first auxiliary carousel which inserts a roll into each seat, oriented with its axis parallel to that of the main carousel, while the roll is partially wrapped with the packaging sheet retained by the closed gripper. In succession, the rear folding device intervenes and the gripper opens and folding means intervene in order to fold the front edge of the sheet onto the rear edge, while the folding device returns to the rest position and the edges are fixed together by a heat-sealing carousel.

Abstract: Layers (14, 15) of the envelope (12) of the packed product (11) overlapped accompanied by the interposing of an adhesive (16) form on one envelope side (13) a strip-like closing field (17) and which for the activation of the adhesive (16) is moved along a corresponding elongated, thermal emitter (9), whose width is roughly the same as the width of the closing field (17). As a result the adhesive (16) does not pass laterally out of the lateral boundaries of the overlap and is instead only activated within its lateral edges (18, 19) by liquefication. The packed product (11) is consequently also thermally treated in a careful manner.

Abstract: The parcel (2) during the conveying with a conveyor (30) is drawn in on the back (7) by angular profiles (16,17) guided in sloping movement paths and which accelerate the parcel (2) accompanied by the alignment of the rotated position and/or its transverse position, transfer same to a stationary surface area (11) and engage same with a stop (12). The angular profiles (16,17) and the stop (12) then form a sliding shaft from which the aligned parcel (2) with a lifting table (32) can be ejected e.g. into a packing station.

Abstract: Apparatus for detecting the coloring of moving tiles for the purpose of dividing their flow into a plurality of flows as a function of the quality of their color. The apparatus detects the color of successive portions of the moving tile and breaks down the detected light spectrum into the three primary colors according to the trichromatic theory. The intensity of each primary color is converted into an electric function by a bank of photoelectric sensors, and this function is processed and compared in a microprocessor with coded signals corresponding to the ideal or optimum coloring that the detected tile should present. The microprocessor emits the signals for automating the division of the flow of scanned tiles into a plurality of flows differing in the quality of the coloring of said tiles.
