Abstract

One or more actuator driven devices on a sheet forming machine receive power and engage in bi-directional Communications with one or more quality control systems either by having no physically connected cables to transmit the power to the actuators (46a, 46b, 46c ... 46n) and no physically connected cables used for the bi-directional communications; or contactless power and communication on a power cable; or a cable connected from the power source to the actuators to provide both power and bi-directional communications; or power is provided to the actuators by a cable and the bi-directional communications are wireless .

Claims (13)

1. A sheet forming system comprising:
one or more quality control systems for use in forming said sheet;
at least one actuator driven device having a plurality of actuators each associated with formation of said sheet;
a module for providing power to said plurality of actuators without having a cable connected between said power providing module and said plurality of actuators;
and a drive signal module connected to at least one of said one or more quality control systems for providing bi-directional communications between said at least one quality control system and each of said plurality of actuators.
2. The system of claim 1 wherein power is provided from said power providing module to each of said plurality of actuators by a transformer arrangement comprising a primary side associated with said power providing module and a secondary side associated with each of said plurality of actuators.
3. The system of claim 2 wherein said transformer arrangement primary side runs from said power providing module adjacent to each of said plurality of actuators and said secondary side is embedded in each of said plurality of actuators.
4. The system of claim 1 wherein power is provided by said power providing module to each of said plurality of actuators by a closed magnetic path from said power providing module to each of said plurality of connectors.
5. The system of claim 4 wherein said closed magnetic path comprises a primary wire providing a magnetic field from said power providing module to each of said plurality of actuators and each of said plurality of actuators comprise means connected to said actuator to intercept said magnetic field provided by said primary wire.
6. The system of claim 1 wherein said bi-directional communications is provided by a cable connecting said drive signal module and each of said plurality of actuators.
7. The system of claim 1 wherein said drive module provides bi-directional wireless communications between said at least one quality control system and each of said plurality of actuators.
8.
