ABSTRACT:
A process for manufacturing brushes for electric motors utilizing a female die with two sheaths intersecting at 90.degree. from each other, one sheath vertical and the other sheath horizontal, and each sheath provided with at least one male die and forming a compression cavity. A batch of conductive powder is introduced into the cavity, and a first compression is performed under displacement control using compression means of one of the two sheaths so as to obtain an intermediate tubular cavity having the cross section of the other sheath. A second compression is then performed under pressure control using the compression means of the other sheath so as to obtain a crude brush of final volume at a desired final compression rate. The compression means of each of the sheaths is moved apart, first those under pressure control and then those under displacement control, and the crude brush is ejected.
