Manufacturing method for spectacles with the use of first and second portions of profiled wire and a pattern having the same form and a size slightly greater than that of the lenses. The first and second wire portions are submitted in succession to different operative phases, in which they are adapted around the pattern so as to form frame half-portions which are shaped around the pattern with the outline of the lenses. The frame half-portions are joined to the respective bars through hinges which are attached to the corresponding frame half-portions, The frame half-portions are submitted, together with the bars to possible chemical treatments, the frame half-portions are applied to the lenses and the bars equipped with the respective terminal elements. Afterwards the nose-piece element is applied on to the assembly frame half-portions by tightening.

A method of producing a metal-coated steel strip includes the steps of forming a metal coating on a steel strip and conditioning the surface of the metal-coated steel strip by smoothing the surface of the strip. The method is characterised in that the conditioning step produces residual stress of no more than 100 MPa in the strip.

Decorative, protective metallic flakes are made by coating a polyplastic web with a release coating; depositing a resin on the release coating; depositing a metal layer on the resin to form a sandwich; and treating the sandwich with a solvent in order to remove the metal and resin layers in the form of metallic flakes.
摘要:
The present invention relates to a method of manufacturing a heat shield and to a heat shield manufactured with this method. Heat shields of this type are particularly used in the field of the automobile industry. According to the method according to the invention, an insulating material, performed in a suitable contour and consisting of graphite, for example vermiculite, without binding agent, is inserted as an insulating plate (4) between two flat materials (2, 3), consisting of sheet metal, for example. The flat materials (2, 3) are then connected to one another at their edges in a positive or non-positive manner. The insulating material is here compressed, before or after being deposited on the flat material, to form a coherent insulating plate.
