A rope saw for cutting panels to size includes an elongate frame, which includes a support for placing panels to be sawn thereon. Two wheels are attached to the frame for mounting a revolving saw rope, between which extends a longitudinal direction of the frame. An electric motor is attached to the frame for driving one of the two wheels. The electric motor includes a motor shaft, which extends in longitudinal direction of the frame and which is coupled via a flexible shaft to one of the two wheels.

A band saw with an expanded cutting section is provided. The band saw includes left and right semicircular shaped bearing assemblies. A saw blade overlaps the left and right semicircular bearing assemblies. An external housing encloses the left and right bearing assemblies and the saw blade. The expanded cutting section is carved into the external housing and extends in between bottom tips of the left and right bearing assemblies.

A laminated rail for a sawmill bed comprises an outer plate having a middle body portion, a top portion, and a bottom portion; and an inner plate secured to the outer plate, the inner plate having a middle body portion, a top portion, and a bottom portion. The middle body portion of each of the inner plate and the outer plate may have substantially the same cross sectional tacking configuration to allow the inner plate to be matingly received by the outer plate. A channel may be formed between the top portion of the inner plate and the top portion of the outer plate, the channel being shaped and dimensioned to receive and secure a track in a sandwich grip.

The present invention relates to a support assembly, a sawhead, and a kit for forming the support assembly for retaining a motor relative to a drive bandwheel and a free bandwheel in a sawmill. The support assembly comprises a first platform orientated on a first plane, where the first platform securable to an axle of the drive bandwheel. The support assembly comprises a second platform orientated on a second plane, where the second platform securable to an axle of the free bandwheel. The support assembly also comprises a centre platform coupled to, and between, the first and second platforms, where the centre platform is orientated on a third plane that is vertically spaced apart from the first and second planes. The centre platform is configured to support the motor above the axles of the drive bandwheel and the free bandwheel.

Disclosed herein is a machine for cutting nozzles of reactor vessels. The machine for cutting nozzles of reactor vessels comprises a cutting unit positioned at an upper surface edge of a reactor vessel having a nozzle and having a saw blade part having different contact areas to cut the nozzle, a drive unit providing the saw blade part with rotary power, and a foreign substance suction unit provided at one end of the cutting unit in contiguity with the saw blade part to suck foreign substances generated when the nozzle is cut by the saw blade part, wherein the foreign substance suction unit sucks the foreign substances by approaching an outer peripheral surface of the nozzle when the saw blade part moves in a cutting direction of the nozzle.

A band saw is disclosed that includes a frame, a guide wheel, and a blade disposed around the guide wheel. A guide wheel chassis can be movably disposed on the frame, the guide wheel rotatably disposed on the guide wheel chassis. The band saw can include a blade tension adjustment assembly including a tensioning motor, wherein operation of the tensioning motor produces movement of the guide wheel chassis and the guide wheel relative to the frame to adjust the tension of the blade. A tension gauge can be positioned to determine a tension in the blade, and a controller can be communicated with the tensioning motor and the tension gauge, the controller operable to receive tension data from the tension gauge and control operation of the tensioning motor based on the tension data to control the tension of the blade.

A sawing machine for bevel cuts having an upper saw portion with two running wheels, one of which is motor driven, a saw band which rotates about the running wheels, a lifting and lowering device for the upward and downward movement of the upper saw portion to move the saw band with a sawing advance movement in a sawing region, a transport path for supplying a workpiece in a supply direction to the sawing region, a frame, on which the upper saw portion is retained and which is pivotable about a vertical axis in order to adjust a bevel angle between the saw band and the supply direction. A movable sawing table is arranged in the sawing region for positioning the workpiece to be sawn and a clamping vice for clamping the workpiece during the sawing operation. The sawing table and the clamping vice are constructed to be movable in and counter to the supply direction.
