摘要： Apparatus for folding collapsible box blanks transversely to a feed direction in which blanks are fed to strip-like tools each pivoted about an axis above a conveyor on which the blanks are supported, and transverse to the feed direction and having a sliding surface forming a ramp which rises from the conveyor in the feed direction downstream of the said axis. Unlike known apparatus, a movable depressor is provided to hold down the blank in the vicinity of the tools and further the folding tools are not driven. In the embodiments described they are restrained by a spring loaded locking device, against free pivotal movement until the torque applied to the tool during feeding of the blank, exceeds a predetermined minimum. In one embodiment, the folding tools are movable in the same direction as the conveyor but at a higher velocity, the resultant relative velocity determining the feed direction.
