An aligning device including an upward straightening appliance consisting of a row of levers equipped with rollers, said levers being mounted for pivoting around a horizontal axis relative to a base member, said base member being mounted for pivotable movement around a vertical axis on a longitudinally extending member, each of the base members being connected by a flexible member to a corner piece shiftable relative to the longitudinally extending member to cause pivoting of all of the base members around their vertical axes, a lower straightening appliance consisting of a driven endless belt supported on rollers arranged vertically aligned to the axes of the upper rollers, an arrangement for biasing the upper rollers against a blank carried on said belt and a lengthwise aligning rail adjustably positioned relative to the upper and lower straightening appliances.
A device for aligning box blanks in a box blank processing machine including a frame supporting a lengthwise guiding rail, an upper carrier and lower carrier which are directly interconnected by brackets and have one end pivotably mounted to the frame adjacent an exit end of the device so that the entrance end of the carriers can be spaced from the rail to provide a lateral movement of a blank against the rail. The position of the entrance end of the carriers is adjustable relative to the guide rail. The upper carrier preferably is formed of a series of rollers and the lower carrier has a series of rollers supporting a belt which is driven by a drive pulley.
