Latest Patents

Hathaway's patent, titled "Method and apparatus for producing valve bags," introduces a novel approach to folding and sealing a web of material to create an item with a contoured seal. This innovation features a folding apparatus that transforms a web of film into a continuous tubular web, consisting of upper and lower sections, a closed side, and an open side. The open side contains two folded flaps that merge into the inner area of the tubular web.

At the core of Hathaway's design is a longitudinal sealer with a floating sealer situated within the tubular web. This floating sealer, equipped with a contoured heating element, is selectively and intermittently pressed against the overlapping flaps to create a contoured seal. This seal not only bonds the flaps together but also defines a self-sealing valve port that allows for easy filling of the bag with products. The use of pairs of repelling magnets elevates the floating sealer, ensuring minimal drag as the web is drawn past it during the sealing process.
