摘要： An apparatus for successively opening the mouths of bags which are fed one by one to a table and putting such bag over a guide hopper for charging the bag with an article to be packaged. The mouth of the bag is sucked by a pair of vacuum suction members from the opposite sides. The vacuum suction members are gradually separated from each other while transferring a bag from a table to the hopper, thereby gradually opening the mouth of the bag. This prevents failures in opening bags and also prevents the bag from separating from the vacuum suction members.
摘要翻译：一种用于将一个接一个地供给到桌子上的袋子的口部连续地打开的装置，并将这种袋子放置在用于对待包装的物品充填袋子的导向料斗上。袋子的口部由相对侧的一对真空抽吸部件抽吸。真空抽吸构件在将袋子从桌子传送到料斗时逐渐分离，从而逐渐打开袋子的口部。这防止打开袋中的故障，并且还防止袋与真空抽吸构件分离。

摘要： A rotary packing apparatus wherein a plurality of bag-support elements support a flexible bag in suspension. The support elements are moved intermittently along an endless circular path, and the bags are fed to the bag-support elements on the path. Thereafter, objects are placed in the bags at a given position on the path. The filled bag is then subjected to a vacuum and sealed. Two vacuum chambers are provided between the position at which objects are placed in the bags and the position for sealing the bags, such that the bags are subjected to a vacuum at each of the two vacuum chamber stages, and are exposed to atmospheric pressure between these two stages.
摘要翻译：一种旋转包装设备，其中多个袋支撑元件支撑悬挂的柔性袋。支撑元件沿着环形圆形路径间歇地移动，并且袋被馈送到路径上的袋支撑元件。此后，物体被放置在路径上给定位置的袋子中。然后将填充的袋子进行真空并密封。在物体放置在袋子中的位置和用于密封袋子的位置之间设置两个真空室，使得袋子在两个真空室阶段的每一个处受到真空，并在这些真空室之间暴露于大气压力两个阶段
