  • Patent number: 4204610
    Abstract: The present invention is concerned with the loading of stencils comprising a plurality of blind bores or holes each adapted to accommodate a decorative article. The stencil is loaded by providing a stack of articles over the stencil and then producing relative translational movement between the stack and the stencil to deposit an article in each hole. Each article is of asymmetric configuration having a generally planar base so that when an article is deposited in a hole base downwards, the article is contained in the hole and when deposited in any other configuration, movement of the stack thereover urges the article out of the hole to allow another article to enter.
