  • Patent number: 4369874
    Abstract: In many branches of industry large quantities of small items (e.g., wire components) or assembly components are frequently required, which have a strong tendency towards entangling and which conglomerate in a pile. These components, termed entangled components, can be isolated only with great difficulty when required for processing. This invention provides a device for isolating such entangled components with relative ease. For this purpose, a horizontal disentangling plate (1) is provided on which the entangled components (7) are placed. A vibrating device (2) shakes the disentangling plate (1) in a reciprocal motion in vertical direction, thus enabling the entangled components (7) to become isolated.
