    • In a first embodiment, a stop having a plurality of ports is connected to and covers an end of a bent rectangular sleeve. In a region near the stop, a narrow wall of the sleeve also has a plurality of ports. The sleeve includes at each bend a pair of oppositely disposed openings, a driven roller, a drive roller cooperating with the driven roller to provide a nip in the sleeve, and a pair of shrouds covering the rollers and openings. A nozzle coupled to a pump provides a flow of air into the other end of the sleeve and the air exits through the ports. With this arrangement, a rectangular sheet inserted into said other end of the sleeve is fluidly brought into registration with the narrow wall and stop, the rollers assisting movement of the sheets through the bends. In a second embodiment, similar to the first, the narrow wall and stop include internal projections against which an inserted sheet is registered. In a third embodiment, similar to the first, a manifold is coupled to the ports and a vacuum pump is coupled to the manifold to accelerate registration. In a fourth embodiment, similar to the third, the pumps are replaced with a reversible pump to register and discharge a sheet.
    • 在第一实施例中,具有多个端口的止动件连接到并覆盖弯曲矩形套筒的端部。 在靠近止动件的区域中,套筒的窄壁还具有多个端口。 套筒在每个弯曲处包括一对相对设置的开口,从动辊,与从动辊配合的驱动辊,以在套筒中提供辊隙,以及覆盖辊和开口的一对护罩。 联接到泵的喷嘴提供空气流入套筒的另一端并且空气通过端口排出。 通过这种布置,插入到套筒的另一端的矩形片流体地与窄壁对准并停止,辊帮助片材通过弯曲部移动。 在第二实施例中,类似于第一实施例,窄壁和止挡件包括内部突出部,插入的片材与该突出部对准。 在第三实施例中,类似于第一实施例,歧管联接到端口,真空泵联接到歧管以加速配准。 在第四实施例中,类似于第三实施例,泵用可逆泵替换以对片材进行排放和排出。
