摘要： An apparatus and method for evacuating and sealing a bag made of a sealable material and containing a comminuted product. The bag is positioned with its open upper end around a sleeve through which a hollow probe can be extended. A pair of upper jaw members close to form an outer temporary seal above an intermediate region of the bag above the level of the surface of the charge in the bag where a permanent seal is to be formed. A pair of lower jaws members close to form an inner temporary seal about a lower region of the bag above the surface of the charge. With the probe extended through the sleeve into the bag, the bag is evacuated through the probe. After evacuation is completed and after withdrawal of the hollow probe, a pair of sealing members close against the intermediate region of the bag in order to form a permanent seal for the bag.

摘要： An apparatus and method for evacuating and sealing a bag (133) made of a sealable material and containing a charge (134) of a comminuted or other flowable product, such as roasted and ground coffee. The bag (133) is positioned with its open upper end around a sleeve (12) through which a hollow probe (14) can be extended. A pair of upper jaw members (UJ) close to form an outer temporary seal about an upper region of the bag above an intermediate region of the bag which is also above the level of the surface of the charge (134) in the bag (133) where a permanent seal is to be formed. A pair of lower jaws members (LJ) close to form an inner temporary seal about a lower region of the bag below the upper and intermediate regions and above the surface of the charge (134) in the bag (133). With the probe (14) extended through the sleeve (12) into the bag (133), the bag (133) is evacuated through the probe (14). After evacuation is completed and after withdrawal of the hollow probe (14), a pair of sealing members (HJ) close against the intermediate region of the bag (133) in order to form a permanent seal for the bag (133). Provision may be made for bleed back into the bag (133), after evacuation thereof, of a small amount of a desirable material such as an aroma fraction or an inert gas such as CO2 or N2.
摘要翻译： 一种用于排空和密封由可密封材料制成并包含粉碎或其他可流动产品（例如焙炒和研磨咖啡）的电荷（134）的袋（133）的装置和方法。 袋（133）定位成其敞开的上端围绕套筒（12），空心探针（14）可以通过套筒延伸。 一对上钳口构件（UJ）靠近在袋子的中间区域周围的袋的上部区域周围形成外部临时密封，该中间区域也在袋子（133）中的充电器（134）的表面的高度之上 ）要形成永久性密封。 一对下颚构件（LJ），靠近在袋子（133）内的充电器（134）的表面下方的上部和中间区域的下部区域周围形成内部临时密封。 当探头（14）穿过套筒（12）延伸到袋子（133）中时，袋子（133）通过探头（14）被排空。 在抽空完成并且在抽出空心探针（14）之后，一对密封构件（HJ）靠近袋（133）的中间区域以形成用于袋（133）的永久性密封。 可以规定在将其排空之后，将数量少的所需材料如香气部分或诸如CO 2或N 2的惰性气体排出回袋（133）。

摘要： A variable capacity reservoir for cigarettes or similar rod-like articles comprises a pair of fixed upwardly extending helical guides located above the normal plane of conveyance of a laterally-flexible mass flow conveyor, and a drive carriage carrying wheels engageable with the conveyor and rotatable about the axis of the helical guides so as to reversibly deflect a variable length of conveyor around said guides. As the conveyor is advanced into or retracted from the helical guides, it is correspondingly transferred from or to a store arranged below the guides.
