Abstract

1,163,007. Photo-electric tension control. CANADIAN GENERAL ELECTRIC CO. Ltd. Nov. 16, 1966 [Nov. 18, 1965], No. 51300/66. Heading G1A. [Also in Division G3] Tension in a moving web is automatically controlled in dependence on the size of a loop formed in the web by differential air pressure and measured by the amount of light reflected from a curved portion of the web. In Fig. 1, a paper web 10 is drawn off a reel 11 and passes over curved surfaces 29, 26 between which is a space 31, with adjustable end walls, to which suction is applied by an exhaust fan 84 so that a shallow loop 32 is formed in the web. Light from a lamp 35 in a compartment 37 passes through a glass roof and is reflected by the paper on to a photo-cell 36 in a compartment 38. The amount of light so reflected is dependent on the size of the loop which is automatically maintained constant by applying the photo-cell output through an amplifier 15 to control a pneumatic, hydraulic, or electromagnetically operated brake 19 acting on reel 11. Other arrangements of lamp and photo-cell are described and, in one, the loop size determines the extent to which the photo-cell is obscured by the web as well as the amount of reflection. The curved surfaces between which the loop is formed may be rollers and air may be blown from above instead of being sucked from beneath the web.
