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.

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.

An edge band fine trimming mechanism of an edge banding machine includes a fixed seat, and a lateral feeler wheel, a top feeler wheel set and a scraper, which are disposed on the fixed seat. The lateral feeler wheel is rotatably disposed on the fixed seat. The top feeler wheel set includes a fixing member adjustably disposed on the fixed seat, and first and second top feeler wheels disposed separately, both rotatably disposed on the fixing member and located at a same predetermined height. The scraper is located between the lateral feeler wheel and the top feeler wheel set for trimming an edge of an edge band of a workpiece. Even though the workpiece has a hole, the scraper is positionally maintainable by the top feeler wheel set, that effectively reduces appearance defects of the end edge of the edge band caused in the edge trimming process.

A method of cutting a workpiece with a band saw includes rotating, with a band saw machine, a blade about a central longitudinal axis. The method also includes supporting a back edge of the blade during the rotating with a back support and a first lateral side edge with a first lateral side support. The method also includes monitoring, with a first sensor, a first level of force exerted against the back support and, with a second sensor, a second level of force exerted against the first lateral side support. The method also includes moving the blade along the axis during the rotating. The method also includes dynamically controlling, with a computing device, the band saw machine during the moving in response to at least one of the first level of force and the second level of force.

A device for cutting a mat or panel made of mineral wool or a board or panel made of porous construction material, including a system for moving the mat or panel made of mineral wool or the board or panel made of porous construction material, which includes at least one conveyor, capable of moving along a direction, an endless diamond element designed to cut the mat or panel made of mineral wool or the board or panel made of porous construction material, a device for running the endless diamond element in a direction perpendicular to the direction of movement of the mat or panel made of mineral wool or the board or panel made of porous construction material, the endless diamond element being an endless diamond wire, an endless diamond cable or an endless diamond strip.

A band saw machine includes a first wheel and a second wheel arranged lower than the first wheel, the first wheel and the second wheel being configured to apply a tension to a band saw blade for tracking, a first supply unit arranged between a lowermost end of the second wheel and a workpiece cutting position along a travelling direction from the second wheel toward the first wheel in a rotary travel path of the band saw blade and configured to spray a cutting fluid in a mist or to drop the cutting fluid onto a tooth part of the band saw blade, and a second supply unit arranged between the workpiece cutting position to the second wheel and configured to pour or spray the cutting fluid or a fluid for cooling over the band saw blade.

The present invention refers to a band saw cutting equipment used, preferably, for the cutting of frozen food products, which has a double band saw cutting system, both in the same cutting plane, with opposite serrated edges on the outside of the said cutting system and with a piece of guidance and separation of the two band saws, that allow the correct position of the band saw to be assured without it bending, maintaining the cutting plane and avoiding that it moves in the cutting plane, avoiding it leaving the pulley system, maintaining a minimum separation between the saws.
