Abstract: A clutch and brake system for starting and stopping a power press uses hydraulically actuated brake and clutch mechanisms. To start the press, the brake is hydraulically released while the clutch is hydraulically engaged at a predetermined intermediate torque level which is less than the full clutch torque level. The clutch is maintained at that intermediate torque level until the present drive shaft has attained its substantially full speed, and is then increased to the full clutch torque level. To stop the press, the clutch is hydraulically disengaged while the brake is hydraulically engaged at a predetermined intermediate torque level which is less than the full brake torque level. The brake is maintained at this intermediate torque level until the press drive shaft has substantially stopped, at which time the brake torque is increased to the full brake torque level.

Abstract: In a method and an apparatus for safe-guarding a press (1) by monitoring the press motion, use is made of the fact that the force exerted by the press is an almost invariable function of the position of the upper press platen in relation to the lower press platen. The force exerted by the press is continuously sensed during each pressure stroke by means of transducers (6). The instantaneous value of the force is compared in a monitoring unit (10) with a reference force value, calculated during the first pressure stroke, at each one of the subsequent positions of the upper press platen of the press in relation to the lower press platen thereof. This comparison is repeated for each such position during the pressure stroke. The monitoring unit (10) directly interrupts the press motion if, on comparison, the sensed force value in any position deviates from the reference force value by more than a predetermined amount.

Abstract: Hay and similar crop materials can be efficiently compacted and formed into pellets or cubes through a closely coordinated sequence of operations in which the hay picked up from the field is deposited into a feed bin, then advanced by gravity feed uniformly onto a cross feed conveyor which advances the hay through a compaction stage in which the hay is precompressed to bale density, and thereafter it is continuously advanced between a pair of counter-rotating press wheels which further compress and form the hay into dense pellets or cubes.

Abstract: A conveyor carries cans or other refuse from a source of cans to a jaw crusher. The conveyor is adapted to drop cans generally one at a time into a bin, and the bin has an opening to release each can when the jaws open to receive it. In the open position, the jaws are spread far enough apart so that the can drops to the bottom thereof. A flap is provided at the bottom to hold the can between the jaws. The end of the flap extends to a position above the bottom of the stationary jaw. As the jaws come together in crushing, the moving jaw cams the flap downward along the stationary jaw. However, the flap is not cammed entirely out of the area beneath the jaw until the jaws have come together to hold the can. The flap ensures that no lip is formed on the can. After the jaws close, the flap is moved out from beneath the jaws so that when the jaws open, the crushed object can fall out of the jaws for carrying away.

Abstract: A method and apparatus for conveying particulate material of the type wherein it is desired that the material be simultaneously pre-compacted from a generally loose state to a more or less solid "plug" state. A screw conveyor is arranged to deliver loose particulate material to an intermediate chamber at the end of the screw conveyor means wherein the material is pre-compacted by the action of the screw conveyor. Following the intermediate chamber, a piston reciprocating coaxially with the screw conveyor further urges the material in a direction coaxial with the centerline of the screw conveyor to further advance the material through a straight coaxial conduit within which the material becomes compacted to an increased degree of compactness, solely by the action of the reciprocating piston. The reciprocating piston has preferably an annular face, whose outside diagram is generally the same as that of the Industrial Design of the conduit.

The position of one or more adjustable rolls is displaced, relative to the common plane through the roll axes, in accordance with the sensing in a manner such that the axis of the adjustable roll or rolls remains parallel to the adjacent roll axis. The adjustable rolls may be displaced horizontally either linearly or arcuately to follow the contour of the adjacent rolls.

Abstract: Press racking, or lateral movement of the movable portions of a press, occurs in certain particleboard processes during heating and pressing of the panels. It is attributed to shingling of wood particles during the formation of a mat. To eliminate or reduce the movement of the press, the mat is subjected to rolling engagement by a relatively small diameter roll located between the forming apparatus and the press. The roll subjects the mat to a downward rolling pressure. The peripheral roll surface is in contact with the newly formed upper surface of the mat and has a linear speed and direction of movement identical to the speed and direction of movement of the mat support. A resulting wave action within the mat is caused by shear and displacement forces applied to the wood particles, such that the shingled nature of the mat is modified to reduce or eliminate resulting lateral movement of the press components.
