Abstract
Improvements in the object of the main patent no. 269,568 for improvements in the manufacture of diffuser sheet supports characterized by the fact of having an upper support ring and a lower one for the ends of diffuser sheets arranged in different planes, so that said sheets they are retained by perfect embedding in the aforementioned rings, in collaboration with the tensile bending of the same, for which a circular vertical wall has been provided in the form of a cylinder with windows for the passage of the ends of the diffusing sheets, which they are housed in some boxes formed by radial projections towards the center of the ring, limited laterally by a partition by a fold, extreme of the projections, and making the sheets the tension bending and perfect embedment by the support of the same in said boxes and in the edge of an extreme crown protruding from the support rings.
