  • Patent number: 5876318
    Abstract: A cushioning conversion machine (10) comprises a frame (36), conversion assemblies (50, 52, 54, 56) which convert a stock material into a cushioning product, and a length measuring device (12) which determines the length of the cushioning product as it is being produced. The conversion assemblies include a rotating assembly (54) and the angular movement of this assembly directly corresponds to the length of the cushioning product. The length measuring device (12) is positioned to monitor the angular movement of the rotating conversion assembly (54) and thus the length of the cushioning product. In the preferred embodiment, the rotating conversion assembly (54) is a gear assembly.
