Circular saw for cutting wooden plate, has duct connecting release orifice and inlet opening, where duct is oriented such that axis is directed towards base of concave curved wall that closes ends of reception volume

摘要

The saw has a collecting units (30) to collect the sawdust ejected from a release orifice (22), where the orifice has a container (32) with two lateral walls (34), a top wall (38) and a base wall (39). The walls delimit a reception volume (40) having ends (45) that are respectively closed by a concave curved wall (48). The container (32) is arranged in a manner that the wall (39) is parallel to a surface Rf. A duct (70) connects the orifice (22) and an inlet opening (60), where the duct is oriented such that an axis (71) is directed towards a base (72) of the wall (48).
