Abstract: A suction conveying device which has a belt conveyor and at least one vacuum chamber extending parallel to the conveyor belt characterized by an obturator engaging an upper surface of the vacuum chamber to close the opening therein when a blank is not engaged thereon. The obturator is preferably a resilient sheet of spring steel which is lifted from a position closing the openings by the movement of a blank across the opening.

Abstract translation: 一种抽吸输送装置，其具有带式输送机和平行于输送带延伸的至少一个真空室，其特征在于，当坯料未接合在其上时，闭塞器接合真空室的上表面以封闭其中的开口。 闭孔器优选地是弹性钢板的弹性片材，其通过坯件穿过开口的移动从闭合开口的位置提升。

Abstract: Apparatus for receiving folded boxes from a machine such as a folder-gluer and stacking said folded boxes in one stack but with portions of the stack in alternately disposed directions to avoid an unbalance in overall thickness of said stack, said apparatus including two box receiving stations located in vertically spaced planes, a shiftable conveyor for selectively moving folded boxes to each of said receiving stations and means for turning over a stack of folded boxes deposited in a first station and then depositing same in a second station on top of other folded boxes already deposited in a second station.

Abstract translation: 用于从诸如文件夹胶机的机器接收折叠箱的装置，并且将所述折叠盒堆叠在一个堆叠中，但是以交替布置的方向堆叠所述堆叠的部分，以避免所述堆叠的总体厚度的不平衡，所述装置包括两个盒接收台 位于垂直间隔开的平面中，用于选择性地将折叠箱移动到每个所述接收站的可移动传送器，以及用于翻转堆叠在第一站中的折叠盒的堆叠的装置，然后将其沉积在已经在其他折叠箱顶部的第二站中 存放在第二站。
