A ring forming step includes welding opposite ends of a band saw blade including a body part having a band shape, and a tooth part including a plurality of teeth formed on one side part of the body part, to form a ring shape. A polishing step includes polishing an inner surface, an outer surface, and an end face on a side opposite to the tooth part in the ring-shaped band saw blade subjected to the ring formation. A tip tooth tip forming step includes positioning, after the polishing step, the ring-shaped band saw blade subjected to the ring formation by use of one of the inner surface and the outer surface, and the end face as references, joining a cutting tip to tooth tips of the plurality of teeth by welding, and polishing the joined cutting tip to form a tooth tip shape.

Provided is a strip edge detection device that can precisely detect an edge of a strip, and that can reduce maintenance labor; and also provided is a brushing apparatus comprising the same.

An edge detection device 7 reciprocates in a width direction of a strip 2, together with brush rolls 3, to detect an edge of the strip 2 in the width direction. The edge detection device 7 comprises a light-emitting portion 8 for emitting light from one side of the front and back surfaces of the strip 2 to the other side; a light-receiving portion 9 for receiving light emitted from the light-emitting portion 8, the light-receiving portion 9 being placed on the opposite side of the light-emitting portion 8 with respect to the strip 2; multiple covers 100 individually covering the light-emitting portion 8 and the light-receiving portion 9; an air injection means 11 for continuously injecting air to the light-emitting portion 8 or the light-receiving portion 9, the air injection means 11 being provided in each cover 100; and a water injection means 12 for injecting water to the light-emitting portion 8 or the light-receiving portion 9 at a predetermined timing, the water injection means 12 being provided in each cover 100.

[Problem] To address the problem of conventional old wood texture or antique taste boards which lack natural looking worn effects and present an appearance of an artificial treatment applied thereto. [Solution] Unlike a conventional configuration in which the rotary shaft of a roll brush is simply and fixedly arranged parallel to the wood grains of a board to which surface treatment is applied or the painted surface where paint is applied to the wood grains, the rotary shaft may be obliquely set to any angle including a right angle, and may be rotationally driven at high speed at a given inclined angle relative to the horizontal surface of the board along a left to right direction of the roll brush. This makes different contact strength of a roll brush such as a metal brush obliquely applied to each right and left end of the board, thereby causing the inclined roll brush to peel off the wood grains or the painted surface where paint is applied to the wood grains with difference strengths for each end of the board. This makes it possible to implement uzukuri (brushing process) with different designs presented along a left to right direction of the board.

A method for producing a metal belt, in which the metal belt is ground at least on one side over essentially the entire surface. In a first step, a transverse curvature in the direction of the belt width is produced on the metal belt by straightening machining, wherein a first side of the metal belt is convexly shaped and a second side of the metal belt opposite the first side is at least planar or concave in shape, and in a second step, the course of the belt thickness in the direction of the belt width is changed to a uniform course of a value of the belt thickness.
