Latest Patents

Rosenbaum's latest patents include a "Method and apparatus for manufacturing foldable conduit." This invention involves a sophisticated process where a sleeve of plastic material is molded into a tubular structure using a blow molding apparatus. The design features two top walls that are longitudinally connected at both base and apex ends. A splitting apparatus is employed to separate the base ends, allowing for the orientation of the top walls with their base ends facing upward. The extruder plays a crucial role in this process, as it extrudes softened plastic that is divided into four flows by a manifold. Four applicators then apply beads of softened plastic along each top wall base end, while a ribbed roller presses flexible strips against these beads. The flexible strips are sourced from finite length rolls, and a splicing apparatus ensures continuous operation by splicing the trailing end of each operating roll with the leading end of the corresponding backup roll. An accumulator maintains a reserve of the flexible strip, allowing for uninterrupted feeding during splices. Additionally, a perforator apparatus and a vent trimmer are utilized to enhance the functionality of the conduit. The folded conduit is ultimately cut to length and wound on reels.

Another significant patent is the "Coupling structure and method and apparatus for its manufacture." This invention features a series of internal couplers that are integrally connected in a single tubing construction of indeterminate length. Each coupler is separated by an annular, frangible region of thin plastic, allowing for easy manual separation in the field. The couplers are designed with cleats that are partially surrounded by a thin plastic material, and they are manufactured through a continuous blow molding process.
