摘要:
A device for pulling up the ends of transverse-conveyed flat tubular segments during the production of sacks or bags comprises lateral support elements, which run parallel to the conveying zone and between which a slit is formed that lies in the conveying plane and beyond which the ends to be pulled up project, and comprising mechanisms for pre-opening the ends by pulling apart the tubular sides that lie on top of each other. To pull up easily the ends of the tubular segments, the support elements in one section of the conveying zone form an obtuse angle in the shape of a peaked roof behind the mechanisms for pre-opening. In this section at least one roll is positioned in such a manner at the support elements that the leading tubular edge strikes the roll.
摘要:
An apparatus for transferring and erecting folded boxes between a dispensing station and a receiving station of a cardboard box making machine. The apparatus includes a plurality of suction systems with suction heads. The suction heads, which each rotate about a common pivot axis, are each coupled to a separate drive mechanism. The device mechanism varies an angular speed of rotation of the respective suction head on a revolution about the pivot axis, so as to adapt this speed to a particular function required at that time. The apparatus has a high output and makes easy adaptation to various folded boxes possible while simultaneously achieving high functional safety and reliability.
