Abstract

Fan rotor composed of: abrasive sheets, which start perpendicular to the axis, forming a body between them once molded the set of groups with axis and resin, then forming a cylinder that we call a rotor fan.the groups of sheets joined together by their internal width and partially by their faces holding and centering said cylinder. The series of sheets of flexible abrasive, on resin fabric of different grain in each model and that although they are completely rectangular for work on flat surfaces, they will be curved, regular or irregular, depending on the work to be done in each case. In its line of unión to the nucleus they take a recess in the form of dovetail (being able to be it of any other form), with the end that when entering in such recess the resin of the nucleus acts of wedge and prevents the detachment of the lámina of the same, with which the axis (figure 7-8), nucleus (figure 3-4) and groups of sheets (figure 5-6) form an indissolubly united whole (figure 9). These sheets whose number and dimensions are variable, are grouped in bundles of two, three or four according to their grain and the work to be done, their size is also conditioned to the same purpose.
