Abstract
Tip for ronocaptora needle, characterized in that it is constituted by a body that is fixed in extension with the corresponding needle, forming a pointed terminal intended to penetrate the groove of a disc, presenting in said terminal a substantially conical profile, slightly ogival, equipped in its front face, with respect to the direction of rotary advance of the disc, of two flat facets adjacent to each other, in obtuse dihedral angle, which give the cross section of the tip a smaller width for the axis between its front and rear faces, which for the axis transverse to the previous, so that the contact of the tip with the walls of the groove takes place by the flanks in curvature, with a large area of mutual contact that proportionally decreases the value of the total pressure exerted against those walls, and so that the running of the tip by the groove of the disc in motion, is facilitated by the aforementioned lower anteroposterior width of the disc. The tip offers less rubbing resistance. (Machine-translation by Google Translate, not legally binding)
