Abstract: A roll stand has a frame in which upper and lower working rolls are journaled for rotation about respective parallel upper and lower working-roll axes and defining a workpiece nip. Respective upper and lower backup-roll guide elements vertically flank the working rolls and are each at least partially vertically displaceable relative to the frame. Respective upper and lower backup-roll journal blocks are axially displaceable but vertically fixed relative to the guide elements and define parallel upper and lower inner axes flanking the working axes. Respective inner backup rolls are journaled in the blocks for rotation about the inner axes and bear radially toward the nip on the working rolls. The inner backup rolls are therefore axially displaceable in the guide elements. A pair of outer backup rolls are journaled in the frame for rotation about outer axes coplanar with the respective inner axes and bear radially toward the nip on the inner backup rolls.

Abstract: The invention is a tool which is used for splitting sections of wood into smaller pieces. In this invention a handle is secured to a wedge-shaped metal piece having a ridge on one side, and to this piece a second driving metal piece is fastened in such a manner that it is allowed to travel slightly on a shaft extending from the first wedge-shaped metal piece, and as its center of gravity is off-centered from the center line of the wedge-shaped piece it causes a twisting or prying motion to be applied to the wood being split. Between the two metal pieces a rubber washer is secured, to temporarily absorb the energy produced by the downward force of the driving metal piece, and then to immediately release said energy into the wedge-shaped piece of metal.

Abstract: The invention relates to a rolling unit having three rollers with axes arranged at 120.degree., wherein the main roller shaft derives its motion from a drive and transmits it to the shafts of the other two rollers through bevel gears. To simplify the assembly and service procedures, as well as to improve the roller adjustment facilities, the main roller is carried on a supporting body which can be removably positioned on the unit casing to allow axial adjustment of the main roller. The respective shaft engages rotatively, but in an axially slidable manner, with a coupling shaft connected to the drive. The supporting body may be attached to the casing radially, thereby it becomes possible to assemble the main shaft, together with the roller, bearings, and gears, and then secure the supporting body on the casing.

The rib members are joined on edge to both the structural member and the base plate and have upper support edges on which the gear housings are secured.

Abstract: A slide and actuator mechanism for the vertical travel of the cutting tool on an Inverted pin routing machine. A slide that provides a rigid support for the cutting spindle and is durable, unaffected by wood dust, adjustable for exact alignment with top mounted guide pin, and inexpensive to manufacture. The actuator lever that moves said slide vertically by applying lifting pressure at the balance point so that the cantilevered motor mount will not cock or bind on the shaft that it rides and thus allows for gravity retract of the motorized cutting tool. Conventional shaft and bushing slides of this type use two shafts with two to four bushings riding on both shafts requiring the shafts to be in absolute perfect alignment to avoid tight spots and binding over the entire travel of the slide. Otherwise expensive alignment devices on the shafts are incorporated or extremely accurate machining methods are required, both of which would put the product price out of the range of the intended market.

Abstract: To reduce the width of slabs from a reheating furnace to the width required in a finishing rolling train, thereby making it possible to feed slabs of only one width, or only a few widths, into the reheating furnace, the invention proposes rolling the slab in a width-reducing roll train in which the slab is subjected to traction such that plastic deformation occurs between the roll sets. In particular the width-reducing roll train has only one set of thickness rolls and has one or more sets of width rolls, thereby minimizing the length of the roll train and consequently reducing the lengths at the ends of the slab which are not subjected to the traction.

Abstract: Deviations from desired shape of plasticly deformable objects are corrected within narrow tolerances by a method wherein the real shape of the object is sensed, whereupon the deviation from the desired shape is determined and a correction length corresponding to the deviation is defined, after which the object in a straightening operation is subjected to a shape correction corresponding to the correction length. At least one measurement transmitter (4) is disposed to sense the real shape of the object (2) and deliver a corresponding output signal which is fed to a unit (6,8,9) for comparison with information about the desired shape of the object stored in the unit for determining the deviation, the unit delivering an output signal defining a correction length corresponding to the deviation, the output signal controlling a straightening device (12,14,16,18,20,22,24) to carry out a correction of the shape of the object corresponding to the correction length.
