Abstract: A device for precise placement of the toe of a hosiery item during automated insertion in the conveyor of a sewing machine for closing the toe, composed of two laminas arranged side by side on a substantially horizontal plane so as to form therebetween a passage for a portion of the hosiery item proximate to the opening of the toe to be closed; the device comprises, proximate to the inlet of the passage, tensioning elements, arranged below the pair of laminas to engage a portion of the toe of the hosiery item, hanging at the toe opening to be closed with two flaps of the opening facing each other and actuated in order to tension the hosiery item downwardly during insertion in the passage.

Abstract: A multipurpose tool for cleaning machines, having a body that is interchangeably associable with a cleaning machine provided with an electric motor; the body is movable on wheels and a front advancement part thereof is arranged transversely to a main direction of motion so as to form a housing that is open downward and accommodates a bristled roller that is moved, by virtue of transmission elements, by an electric motor accommodated within the body; the body is articulated to a coupling element that is suitable to provide a detachable connection to the machine with a dirt suction duct. The tool further includes a pair of interchangeable covers that are selectively detachably associable below the housing at an open region where the roller is located, each of the covers having at least one suction slot and elements for closing the region to the rear of the roller between the housing and the floor.

Abstract: A four-sided insert for milling cutters with negative radial angle of the cutting edges for three-dimensional milling from a solid, which has an upper face, or rake face, that is delimited by four sides that constitute the cutting edges of the insert. The four sides are opposite in pairs and connected to corresponding sides of the lower face by lateral faces. Two opposite sides of these four sides constitute main cutting edges of the insert and the other two sides constitute secondary cutting edges. The lateral faces that connect the main cutting edges to the lower face of the insert have, proximate to one end or tip of the cutting edge, a positive lower relief angle that is greater than the lower relief angle, which can be positive or negative or nil, proximate to the other end or tip of the cutting edge.

Abstract: A dispenser of single-use portions of preparations for beverages, comprising a structure that supports at least one storage assembly for single-use portions provided with a discharge outlet for the discharge of the portions, at least one distribution assembly for the portions which is provided with an outlet for dispensing said portions and with a device for transferring the portions from the discharge outlet to the dispensing outlet, which are interposed between the storage assembly and the distribution assembly.
