INTERMITTENT COATING OF MOVING SURFACES

摘要

A method of intermittently coating a moving surface with paste containing electrochemically active particles by a nozzle having a slot-shaped delivery opening includes supplying paste to the delivery opening from a paste reservoir via a transport channel and regulating paste supply to the delivery opening with a rotatably mounted control axle which enables the paste supply to the delivery opening in a first switching position and, in a second switching position, blocks the transport channel and disconnects a section of the transport channel extending as far as the delivery opening from the paste supply, wherein the rotatably mounted control axle includes a passage via which the paste reservoir is in communicating connection with the delivery opening in the first switching position and the disconnected section of the transport channel is in communicating connection with the reduced pressure source in the second switching position.

1. A device that intermittently coats a moving surface with a paste containing electrochemically active particles comprising:
a nozzle having a slot-shaped delivery opening, a paste reservoir from which paste being supplied to the delivery opening via a transport channel and a rotatably mounted control axle that enables the paste supply to the delivery opening in a first switching position and, in a second switching position, blocks the transport channel and disconnects a section of the transport channel extending as far as the delivery opening from the paste supply, wherein the rotatably mounted control axle comprises a passage via which the paste reservoir is in communicating connection with the delivery opening in the first switching position and via which the delivery opening is in communicating connection with the reduced pressure source in the second switching position.
