摘要： A machine for forming molded foam cushions, including an apparatus for enclosing a foamable composition in a flexible bag; a mold having a cavity and a closure mechanism and being movable between an open position and a closed position such that, when in the closed position, the closure mechanism and the cavity define an enclosed three-dimensional shape, the mold comprising a material capable of transferring sufficient heat to or from the cavity to maintain the cavity at a desired temperature; a device for controlling the temperature of the mold cavity; means for placing the bag in the mold cavity while the mold is in the open position, whereby, when the mold assumes the closed position, the foamable composition expands within the cavity to form a foam cushion that substantially conforms to the three-dimensional shape; and means for pulling the foam cushion from the mold cavity.

摘要： A packaging device is disclosed for forming packaging cushions of the type that include a plastic bag filled with a solid foam, and wherein the cushions are initially formed of a plastic bag filled with a foamable material that reacts and then hardens to form solid foam. The device comprises means for advancing a sheet of plastic film material that has been center-folded to form a doubled web with one closed edge defined by the center fold and one open edge defined by the adjacent edges of the sheet. Means are included for injecting a foamable composition into the center-folded web between the two folded portions of the sheet, as are means for forming a substantially linear seal along the open edge and substantially parallel to the open edge to thereby longitudinally seal the open edge of the web. The invention further includes means for periodically interrupting the linear seal to provide an unsealed portion along the otherwise sealed edge, and means for transversely sealing the web after foamable composition has been injected, and for concurrently separating a formed and filled bag from the advanced film material.
摘要翻译：公开了用于形成包括填充有固体泡沫的塑料袋的类型的包装垫的包装装置，并且其中所述垫最初由填充有可发泡材料的塑料袋形成，所述可发泡材料反应然后硬化以形成固体泡沫。该装置包括用于推进已经被中心折叠的塑料薄膜材料的片材，以形成具有由中心折痕限定的一个封闭边缘和由片材的相邻边缘限定的一个开口边缘的双重幅材。包括用于将可发泡组合物注入到片材的两个折叠部分之间的中心折叠的卷材中的装置，以及用于沿着开口边缘形成基本上线性的密封并且基本上平行于开口边缘的装置，从而纵向密封开口边缘的网页。本发明还包括用于周期性地中断线性密封以提供沿其他密封边缘的未密封部分的装置，以及用于在可发泡组合物已被注射之后横向密封纤维网的装置，以及用于将形成和填充的袋与先进膜材料同时分离的装置。
