Abstract
A vibratory apparatus and method for agglomerating chopped bundles of wet fiberglass strands into uniform segments includes a container having a curved inner surface disposed about a generally horizontal axis where the container is mounted on a plurality of springs. The chopped bundles of wet fiberglass strands to be agglomerated are placed onto the curved inner surface at an input end of the container. A vibratory force is produced to cause the chopped bundles of wet fiberglass strands to be moved from the input end toward an output end of the container. The vibratory force causes the chopped bundles of wet fiberglass strands to be directed in a rising and falling path of rolling movement within the container. As a result of the rolling movement of the chopped bundles within the container which is produced by the vibratory force, the chopped bundles of wet fiberglass strands are converted into uniform segments by reason of agglomeration of the wet fiberglass strands.
