  • Device for feeding substrates to vacuum systems for deposit of surface coating on the substrates
    Patent number: 6143148
    Abstract: A process for supplying plants for the coating of substrates involves introducing the substrates batchwise into the vacuum plant and, subsequently, dividing said batches into single substrates in order to allow recovery of the unsaturation percentage, which is connected to the method used to feed in the batch.The device suitable to provide this process is made up of transport sections capable of giving the substrates forming the batch different speeds from one another, so as to separate them and line them up, with a pre-set constant spacing, in a continuous line of substrates feeding the process chambers (B3, C3).
