Abstract

Process for manufacturing flat grids for cathode ray tubes, of the type in which a strip of threads, corresponding to the one to be fixed on the grid frame, is firstly accommodated to the length of the threads between two distribution rods with grooves, parallel to each other, the frame being arranged between the two rods and below the belt, the wires then being fixed to two or more sides of the frame by embedding in a fusible material, without deformation of the frame. girdle, and then the useful part of the girdle is separated, by sectioning the threads, from the part of the girdle that subsists externally to the frame, characterized in that the girdle stretched between the two distribution rods results from the transformation, by means of of a tensioning device, of a winding obtained by winding a continuous thread around two sides, provided with slots, of a winding support, carrying said device tensioner to the same plane between the two distribution rods the two parallel belts formed by said winding.
