Abstract: A mobile crusher includes: a crusher that crushes raw material; a discharge conveyor being disposed on a downstream side of the crusher to discharge the material crushed by the crusher; an engine that serves as a driving source at least for the crusher and the discharge conveyer; a fuel injection quantity controlling unit that controls a speed of the engine; a crusher pressure sensor that determines a change in a load of the crushed material in the crusher; and a pressure sensor that determines presence or absence of the crushed material to be discharged on the discharge conveyor. When the crusher pressure sensor determines that the load on the crusher is reduced and the pressure sensor determines that the crushed material is not present on the discharge conveyor, the fuel injection quantity controlling unit lowers the speed of the engine to a decelerated speed.

Abstract: A shredder includes a housing having a throat for receiving at least one article to be shredded, and a shredder mechanism having a motor and cutter elements. The shredder also includes a detector that is configured to detect a thickness of the at least one article being received by the throat, and a controller that is configured to operate the motor to drive the cutter elements to shred the at least one article and to set a flutter threshold higher than the predetermined maximum thickness threshold, if the detected thickness is less than a predetermined maximum thickness threshold. The controller is also configured to thereafter continuously detect the thickness of the at least one article being inserted into a throat of the shredder; and to perform a predetermined operation responsive to the thickness detector detecting that the thickness of the at least one article is greater than the flutter threshold.

Abstract: A method and a system for glulams fabrication, comprising obtaining wood pieces of a target length from raw materials; and assembling them into structural timbers of a target thickness in a continuous line, whereby moisture content, end joints, mixing and applying of adhesives, glue line pressure and clamping time are continuously controlled.

Abstract: Method for manufacturing floor panels with coupling parts, wherein the contour of this coupling part (6) is composed of at least two portions (18-19), characterized in that the method is applied for manufacturing at least two series (7-8) of floor panels (1), wherein the floor panels (1) in a first series (7) differ from the floor panels (1) in a second series (8) at least in that they have a different thickness (T) and that said two portions (18-19) in said series (7-8) of floor panels (1) are realized globally identical, however, mutually shifted.

Abstract: A self-propelled crushing machine comprises a crushing device 20; a hydraulic drive system including a crushing device hydraulic motor 21 for driving the crushing device 20, a first hydraulic pump 62 for driving the crushing device hydraulic motor 21, and an engine 61 for driving the first hydraulic pump 62; a pressure sensor 151 for detecting a load condition of the crushing device 20; and a controller 84? for executing control to increase a revolution speed of the engine 61 in accordance with a detected signal from the pressure sensor 151. Accordingly, even when a heavy load is imposed on the crushing device, a reduction of crushing efficiency can be prevented.

Abstract: A method for manufacturing a wood veneer surfaced furniture top with a profiled edge, utilizing a special tool and process, which when used collectively, eliminates the need for certain relatively costly machinery and manufacturing processes.

Abstract: A combination finger joint cutter head having a pair of adjustable cutter assemblies, that cut a plurality of finger joints in an end of a wood piece, and a pair of adjustable trim knives, wherein a single adjusting means extends or retracts the pair of knives, thereby changing the finger joint length slightly to either loosen or tighten the joint.

Abstract: A stacked disc cutter assembly for producing finger joints including a plurality of discs, each of which has a plurality of cutter teeth secured to and projecting radially outwardly therefrom. The discs are of substantially similar outer diameter and when assembled and secured together in side-by-side, contiguous, concentric relationship they form a solid cylindrical core for the assembly. The cutter teeth projecting radially outwardly from the discs and so arranged on the discs that they are spaced apart both axially and circumferentially of the cutter assembly. SUBACKGROUND AND SUMMARY OF THE INVENTIONThis invention relates to a stacked disc cutter assembly for producing finger joint cuts in material, and more particularly to such a stacked disc finger joint cutter assembly wherein cutter teeth thereon are spaced apart both axially and circumferentially about the assembly.In the past, various types of cutter devices have been designed for producing finger joints in material such as wood.

Abstract: A machine for processing wood logs for construction of log houses. The machine includes a power feed to load the logs into a self-centering device. A carriage assembly is centered about the log and the log is mounted in the carriage on powered centers so that the log can be rotated. The carriage travels longitudinally on tracks past one, or a plurality of cutters, which as the log rotates cuts the log down to a selected diameter. After the log is cut to diameter it is again passed longitudinally along the tracks and two cutters are positioned at equal distance above and below the axis of the log to cut tongues and grooves on the top and bottom of the log, respectively. Means are provided for cutting a saddle notch underneath the log, to cut the logs to precise length, and to cut a vertical notch in each end for the purpose of joining logs end to end. Means are provided for rapid removal of the chips cut from the logs.
