  • Patent number: 8334191
    Abstract: A system for treating distinct batches of workpieces to serial procedures comprises first and second multi-site structures. In each multi-site structure the sites are rotatable for alignment in turn with loading and unloading stations together constituting treatment or process stations. Workpieces of a batch are loaded onto all of the treatment sites and then simultaneously and identically treated by operation of treatment stations with which the process sites are aligned. After treatment in the first structure, workpieces of a batch are transferred from the unloading stations of the first structure to the loading stations of the second structure for further processing.

  • Patent number: 5776520
    Abstract: An automatic glove stripping machine is disclosed comprising a drive unit that distributes power to one or more stripping assemblies, each comprising a conveyor unit, a plurality of dipping molds, a pressurized air distribution system, a brush set, a plurality of grip assemblies, and a cam assembly. Each grip assembly is moved into engagement with a set of dipping molds retaining dip molded articles such as latex gloves. As each grip assembly and corresponding set of dipping molds travel over the stripping assembly, the molded articles on the dipping molds are partially removed by action of the grip assembly and a stream of pressurized air directed at each mold. As the set of dipping molds reaches the end of the stripping assembly, the molded articles are completely removed from their dipping molds by the brush set.
