ABSTRACT:
A speed control system is provided for apparatus and process for shaping and treating web material of indefinite length wherein the apparatus includes a master processing unit, one or more slave processing units communicating with the master unit through web storage or buffer means and a computer. Information as to the desired speed and mode of operation of the master unit and the mode of operation of the slave units is inputted to the computer which communicates with the drive motors of the master and slave units through special buffered isolated amplifiers and automatically controls the speed of the slave units so as to maintain the desired quantity of partially processed web material in the web storage means and to maintain the selected operating speed of the master unit.
