Abstract: The invention relates to steel-rule cutting dies having a die block with at least one kerf configured to receive a corresponding steel-rule intended to be partially inserted into the kerf. The die block also has at least one element having magnetic properties, such as for instance a magnet, located or embedded in proximity to each kerf for providing a magnetic field that retains the steel-rule when the steel-rule is received into the corresponding kerf. The presence of the magnetic element(s) in proximity to the kerf(s) allows maintaining the corresponding rule(s) in position within its kerf even if the kerf is cut “loosely”. The corresponding rule may be quickly and easily inserted and accurately maintained even if the die block expand or retract under atmospheric variations. Among other advantages, the invention allows better stability of the cutting-die, faster leveling on press, and increased the number of re-knifing and longer run-time.

Abstract: A colloid mill utilizes a motor-driven shaft configuration that connects to the rotor of the colloid mill to the electric motor rotor. In this way, the mill rotor shaft is directly driven. Complex gear or belt drive arrangements between a separate electric motor and the fluid processing components of the colloid mill are thus avoided. Moreover, the gap between the mill rotor and mill stator can be adjusted simply by axially translating the motor-driven shaft. Such translation is provided by a timing belt-based arrangement to limit backlash. As a result, a simple hand-operated knob or stepper motor arrangement can be used to control the gap.

Abstract: A forage harvester cutterhead of the type having a rotatable member carrying circumferentially spaced cutting knives. Each knife is beat such that a leading cutting portion is directed radially inwardly of its trailing portion and ahead of its knife support so as to provide better cutting power efficiency and more clearance for its mounting means. The bent knife configuration allows a thinner knife edge to be used and provides improved quality and uniformity in cut crop material. The thinner knife cuts through mat of material with less force and less disturbance to uncut material resulting in fewer long particles pulled from mat and much fewer long cob particles. Corn cobs are not dislodged from mat due to lower cutting force and hence are sliced up neatly.

Abstract: A novel cooperative blade construction for the rotor and bed knives of a size reduction machine such as a granulator and the like wherein each of the blades are of an overall chevron configuration so as to form a generally trapezoidal opening therebetween. As the blades progressively move past each other, the height of the trapezoidal opening is reduced such that articles to be granulated are initially contacted at opposed laterally spaced points on opposite sides thereof such that articles are clamped and progressively cut with a minimum of energy consumption, noise and fines production. The generally centrally located peaks of the rotor blades and the bed knife blades are also arcuately displaced away from a radial plane passing through the opposite side portions. The blades progressively move past each other while maintaining an equal cutting gap therebetween.

Abstract: In a beam-backed cluster-type strip mill each roll is driven separately from a vertical motor placed on top of the housing through a floating right-angle gearbox. The gearbox is keyed onto one end of each roll and is so suspended that only pure torque is transmitted to the roll and the reactions as well as the weight of the box are absorbed by the suspension means.Roll oscillating mechanism, forcing the rolls to travel axially back and forth far enough to efface marks left by the backing casters, is incorporated in the gearbox.This drive possesses substantial advantages over conventional drives, which make the mill more accessible, and save space. Moreover it makes possible various roll configurations by adding supplementary rolls to the cluster pattern thereby increasing the range and scope of the mill.
