A blade guard assembly for a circular saw blade of a saw house includes a blade cover with a face panel and an edge portion that extends from the face panel. An actuator is mountable the blade cover and the structure of the saw house. When the blade guard assembly is mounted in saw house, the blade cover is movable with the actuator between a covered position and an exposed position. In the covered position, the face panel and edge portion at least partially surround the saw blade. In the exposed position, the face panel is spaced from the saw blade.

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 cutting apparatus includes a blade changing apparatus for changing a cutting blade mounted on a spindle of a first cutting unit and changing a cutting blade mounted on a spindle of a second cutting unit. The blade changing apparatus includes a nut mounting and demounting unit for mounting and demounting a nut in each of the first and second cutting units and a blade mounting and demounting unit for mounting and demounting the cutting blade in each of the first and second cutting units. The nut mounting and demounting unit includes a rotating shaft, a first nut rotating portion fixed to one end of the rotating shaft, a second nut rotating portion fixed to the other end of the rotating shaft, a motor, and a power transmitting unit connected to the motor and the rotating shaft.

A method produces a frame for a transport device for receiving slices of material separated by a cutting blade of a cutting machine. The method includes: providing a single integral workpiece, the single integral workpiece having a base plate region, a first longitudinal side region on a first side of the base plate region, and a second longitudinal side region on a second side of the base plate region, bending the first longitudinal side region along a first longitudinal side bending edge until the first longitudinal side region is perpendicular to the base plate region, and bending the second longitudinal side region along a second longitudinal side bending edge until the second longitudinal side region is perpendicular to the base plate region. The first longitudinal side region and second longitudinal side region each extend away from the base plate region in a first direction, and are parallel to each other.
