    摘要: Described herein is a self-threading screw, designed to be inserted in a hole of appropriate size made in a sheet of metal (or other metallic body), which has at the free end of its shank six projections (“formers” or “shapers”) of prismatic shape designed to thread by rolling the wall of the hole in which the screw itself is inserted.

    摘要: Method and device for resetting the position of pins in trays with pins for supporting objects to be clad inside presses, comprising a tray arranged on a substantially horizontal plane and in which there are multiple receptacles having a substantially vertical axis, each receptacle accommodating a pin provided with a head protruding from the upper face of the tray. The pins form with their heads a supporting surface for the lower face of the object to be placed in the press. Each pin has elastic means that keep the pin in a raised position and are flexible so as to allow the pin to pass from the raised position to a lowered position or vice versa. The method consists in making the tray slide along a resetting surface having, along its extension, a region raised with respect to a plane that is parallel to the plane of arrangement of the tray. The raised region is suitable to gradually make contact with the lower end of the pins in the lowered position, as they pass at the raised region, to produce their transfer to the raised position.

    摘要: The screw, of the type provided with a coaxial recess adapted to mate with the tip of a screwing tool has in plan view a configuration in the overall form of a star with six chamfered points, with the lateral walls of the recess flared outwards and inclined to the screw axis by an angle of between 7 and 15 degrees. The sides of the chamfered points of the star consist of flat surfaces, pairs of which form on the lateral wall of the recess six corresponding ribs of isosceles triangle cross-section, the angle at the vertex of the isosceles triangle being substantially 90 degrees and the height of the triangle being substantially equal to one half the base length of said isosceles triangle. The screwing tool has a tip which mates with the lateral walls of the screw recess.
