20240157593 · 2024-05-16 · ·

A sawmill and a kit for forming the sawmill has a support assembly, a sawhead, a log bed and a carriage. The support assembly retains a motor relative to a drive bandwheel and a free bandwheel in a sawmill. The support assembly has a first platform orientated on a first plane, where the first platform securable to an axle of the drive bandwheel. The support assembly has a second platform orientated on a second plane, where the second platform securable to an axle of the free bandwheel. The support assembly also has 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.

A GUIDE BLOCK ASSEMBLY, A BAND SAW UTILIZING TWO OPPOSITE GUIDE BLOCK ASSEMBLIES AROUND A CUTTING SECTION OF THE SAW BLADE, A METHOD OF MOUNTING THE GUIDE BLOCK ASSEMBLY AND THRUST SLATS FOR THE GUIDE BLOCK ASSEMBLY
20190210128 · 2019-07-11 ·

A guide block assembly for controlling a saw blade of a band saw during cutting. The assembly includes a mounting part having a rear part adapted for securing the guide block assembly to the band saw frame and a front part for detachably securing a thrust part. The thrust part includes at least two thrust slats detachably secured in the front part of the mounting part. The slats are aligned and spaced apart around a center section of the front part. When using the guide block assembly, vibrations, chattering and heating of the saw blade are substantially reduced, and the production rate and speed are increased. The guide block assembly is typically used for band saws that have a cutting speed of between 1800-6000 m/min, pulley wheels having diameters of 1000-2500 mm, and saw blade widths in the range of 80-360 mm.

Band Saw Machine
20190210127 · 2019-07-11 ·

A band saw machine has two deflection pulleys arranged one above the other in the vertical direction, an endless saw band, which is guided around the deflection pulleys and which has an upward running portion and a downward running portion, and a machine frame, which has a saw neck for holding at least the upper deflection pulley. The deflection pulleys are arranged substantially parallel to a front edge of the machine frame, so that both the upward running portion and the downward running portion of the saw band face towards the front edge with their cutting edges. The saw neck is arranged offset from the deflection pulleys from the front edge (6) to the rear. Both the upward running portion and the downward running portion of the saw band are at least partially exposed between the deflection pulleys.
