摘要： A packaging machine wherein product-loaded cup-shaped receptacles are advanced with an indexing movement through a series of packaging stations. One station includes a fixed vacuum/gas chamber extending entirely over one set of receptacles. The receptacles are first evacuated through this fixed chamber, and thereafter gas is directed into the chamber to fill the receptacles. A fine wire-mesh screen is positioned between the chamber and the receptacles to constrain the air and gas flow to a vertical direction, to prevent disarrangement of the product during evacuation and gassing. A gas-curtain structure develops an enclosed region of gas above the receptacles during their movement out from under the fixed chamber over to the final sealing station. The sealing operation takes place in two successive steps within the sealing station.
摘要翻译：一种包装机，其中产品装载的杯状容器通过一系列包装站的分度运动而前进。一个工位包括一个固定的真空/气体室，其完全在一组容器上延伸。首先将容器排出通过该固定室，然后将气体引入室以填充容器。一个细金属丝筛网位于腔室和容器之间，以将空气和气体的流动约束到垂直方向，以防止排气和放气期间产品的排列。气幕结构在它们从固定室下移动到最终密封站的过程中，在容器之上形成封闭的气体区域。密封操作在密封站内连续两个步骤进行。
