ABSTRACT:
A system and method for depositing a pattern of media on a moving surface includes a media depositing apparatus that deposits media in a predefined pattern on the moving surface. A media applicator roll having a media receiving region, such as engraved or raised portions, receives the media from a media feeder as the media applicator roll rotates. A media retaining member maintains the media in contact with the media receiving region until the media reach a bottom region of the media applicator roll and are released from the media applicator roll in the predefined pattern onto the moving surface. The media depositing system also includes a multiple compartment media feeder that selects and selectively feeds one or more of multiple types of media or granules to the receiving region of the media applicator roll. The method for depositing a pattern of media includes synchronizing the speed of rotation of the media applicator roll with the speed of the moving sheet of material so that the media are precisely deposited as they are released from the media receiving region. The method also includes minimizing the distance that the media must drop from the applicator roll receiving region to the moving surface.
