Abstract
876,221. Automatic control systems for moving webs. ELECTRIC & MUSICAL INDUSTRIES Ltd. Dec. 20, 1957 [Jan. 2, 1957], No. 126/57. Class 38 (4). [Also in Groups XVI and XXXVIII] In a web feeding apparatus (see Group XVI), weighing platforms 10, 11 associated with bins 4, 5 operate switches, not shown, in the circuits of electric motors, not shown, which drive spools 2, 3. When web is being drawn from the bin 4 by a roller 7, the associated switch remains open until the quantity of web within the bin, as detected by the platform 10, reaches a predetermined minimum. When this minimum is reached web is unwound by driving the spool 2 upon closure of the switch controlling its motor. Similarly, when web is being fed into the bin S by the roller 8, the corresponding switch for controlling the motor driving the spool 3 remains open until a predetermined maximum as detected by the platform 11 quantity is reached whereupon its associated motor is energized to wind web on the spool 3.
