Abstract: Disclosed is a machine for forming preimpregnated composite material into thin, narrow structural elements or "fillets" (18). The machine includes a cylindrical lower forming roll (26) rotatably mounted at its ends between two side plates (40). A cylindrical upper forming roll (28) is mounted above the lower forming roll and urged into frictional contact therewith. Annular protrusions (30) are formed in the periphery of the lower forming roll and project radially therefrom. Each protrusion comprises a groove (34) formed in its outermost surface that defines a die. The die, with the outer surface of the upper forming roll, combine to form an orifice (35). Each orifice is shaped substantially identical to the cross-sectional shape of the fillet. A strip of composite material (24) is fed through a series of guides and into a selected orifice. A drive mechanism (36) causes rotation of the lower forming roll and hence the frictionally contacting upper forming roll.

Abstract: A surface of a wedge acts as a stop to limit travel of a spindle on an automatic riveting machine. A drive mechanism moves the wedge back and forth to vary the heighth of the wedge, and the same mechanism simultaneously moves a rod back and forth to act on a transducer, and transmit an electrical signal to give a digital readout of the change in heighth of the wedge.
