Title: Photo-electric selvedge control device
IPC: D06C3/00
Filed: 1954-04-21
Abstract: 760,424. Photo-electric selvedge control. AKT.-GES. BROWN, BOVERI & CIE. April 21, 1954 [April 22, 1953], No. 11538/54. Class 40 (3). A device for selvedge control wherein a beam of light 2 is shaded by the fabric edge 7 to a degree depending on its lateral position is characterized in that light shields with apertures 4, 5 and 6 are provided for distributing the beam over two photocells 10, 11 so ar. ranged that the aperture 4 of the light shield for photocell 10 is partly covered by the fabric edge 7 and that the apertures 5 and 6 are always without and within the fabric edge respectively, the cells being connected so that their voltage difference produces a control potential the zero value of which, i.e. when edge 17 coincides with the centre line of aperture 4, is independent of the light source intensity and fabric permeability. The areas of apertures 5 and 6 are the same and their sum is equal to the area of the third aperture 4 so that when the edge of the fabric shades half of diaphragm 4, the illumination of the two cells is the same irrespective of variations of source intensity and absorption by the fabric, provided this is uniform. In a modification the cells and apertures and the source are all on the same side of the fabric and a right-angled prism with its axis normal to the fabric edge is used on the opposite side to direct the light beam through and past the fabric edge to the aperture system. A reflecting surface may replace the prism, while in a further modification of this arrangement the fabric which reflects to a certain extent runs over a highly absorbent surface, so that in this case the shaded and unshaded parts of the beam reaching the apertures are reversed. A further optical system may be used to produce an image of the edge region, the light from which then passes through the apertures.
