  • Patent number: 3982876
    Abstract: A conveyor belt is formed with depressions which are bounded by sealing edges, and tiles corresponding to the outline of the respective depressions are continuously admitted from above onto the belt and inserted into the depressions so as to be in sealing contact with the respective sealing edges. A layer of hardenable synthetic plastic material is then deposited on the belt over the tiles so that the latter are partially embedded in and united by the layer when the same hardens, thereby obtaining a unitary structure. Subsequently this structure is subdivided in plate elements of desired size.

  • Patent number: 3964858
    Abstract: The invention relates to a candle-wicking machine which automatically operates to insert a candle wick into a candle after the candle has been formed to its desired shape. A plurality of candles can be wicked at the same time. Essentially, wicking material is cut to length, and then engaged near one end with a wicking rod that is forced down into the candle carrying the wicking material with it and depositing the wicking material into the candle on removal of the wicking rod. The essence of the invention lies in proper association of the wicking material with the wicking rod, cutting the wicking material to proper length, and the engagement of the wicking rod with the wicking material to force it into the candle.
