Claims

[Scope of utility model registration request]

A table having a planer blade and an elevating member having a material feeding belt driven by a first reversible electric motor are opposed to each other to form a material feeding path for the workpiece, and a second elevating member is provided at a suitable position above the elevating member or the elevating member. In the super finishing planer for woodworking, which is equipped with a reversible electric motor and a lifting screw to automatically raise and lower the lifting member, when feeding the workpiece, the intervals between the material feeding paths are set to appropriate intervals. In addition to the means for automatically setting the distance between the material feeding paths, there is also a means for detecting the movement amount of the lifting member, and a means for detecting the movement amount of the lifting member, and a mechanism that allows the lifting member to mechanically freely move up and down due to changes in the longitudinal thickness of the workpiece during material feeding. a vertical motion determining means for determining in which direction the elevating member has moved up or down in response to an output signal from the movement amount detecting means when the elevating member has moved up and down as far as possible, and an output from the vertical motion determining means; A super-finishing planer for woodworking, comprising means for driving the second reversible electric motor for a predetermined period of time to raise and lower the elevating member according to the direction of change in the longitudinal thickness of the workpiece.
