Abstract: The cylinder supports a series of knives at its outer periphery which extend generally parallel to the axis of rotation of the cylinder, spanning a plurality of supporting bulkheads that are provided with special mounting assemblies which adjustably attach the knives thereto. The knives are positioned in such a way that in order to adjust the radial position of a cutting edge, the knives are adjustably shifted either inwardly or outwardly in a direction that is normal to the plane of the knives being adjusted. As a result of a degree of inherent flexibility of the knives, certain of the attaching points may be adjustably positioned more inwardly or outwardly than others by causing the knives to flex appropriately at the needed locations. Each attaching or mounting assembly includes a pair of threadably interengaged components, one of which shifts inwardly and outwardly upon rotation of the other so as to correspondingly position the proximal knife portion after a clamping bolt has been sufficiently released.

Abstract: A stack-forming machine has a telescoping container defined by a vertically reciprocable, downwardly concave press that is received within an upwardly concave lower section that remains stationary during reciprocation of the press. When the press is raised and an upper door on the press and a lower gate on the lower section are opened, the stack may be discharged from the container. The upper door is normally held closed by an overlapping portion of the lower gate, the latter in turn being releasably latched in place, and while the lower gate is swung downwardly by gravity to its opened position as the press is raised, the upper door is powered to its open position through linkage that interconnects the door with the lower section of the container so as to utilize the upward movement of the press as the source of opening power for the door.
