Abstract

Deformable foil surfaces, in the general cross-sectional shape of a triangle, are deflected to selectively guide or valve paper sheets into an inverting station, or to bypass the inverting station. This arrangement is illustrated in Fig. 1 where the bypass paper path is adjacent to surface I, the path to the inverting station is adjacent to surface II, and the output path from the inverter is adjacent to surface III. Point C is fixed. Points A and B are movable, and they are linked so that they move simultaneously toward surfaces I and III, respectively, to insure paper passage through the path next to surface II.

Diverting Valve

Deformable foil surfaces, in the general cross-sectional shape of a triangle, are deflected to selectively guide or valve paper sheets into an inverting station, or to bypass the inverting station. This arrangement is illustrated in Fig. 1 where the bypass paper path is adjacent to surface I, the path to the inverting station is adjacent to surface II, and the output path from the inverter is adjacent to surface
III. Point C is fixed. Points A and B are movable, and they are linked so that they move simultaneously toward surfaces I and III, respectively, to insure paper passage through the path next to surface II. When the invert function is selected, point A moves against surface I and point B moves against surface III; this allows free passage of the paper into the inverter, which will then reverse the direction of travel of the paper. When the trailing edge of the paper has cleared point B, the direction of paper movement is reversed, and points A and B return to be adjacent surface II, which causes the paper to be guided past surface III on its way to the exit. This valve construction is illustrated in Fig. 2. Three thin steel strips or plates are flexed and then joined by spot or seam welds at points A, B and C, as is indicated by the dots in the figure. When a force (see the arrow of Fig. 3) is applied to this structure, assuming point C is fixed, points A and B will turn about hinge points V to produce the desired shift in the vanes, for es...
