The method for inspecting a length-measurable product includes manufacturing the length-measurable product 1 whose length at least in one direction can be measured, when a defect 4 occurs in the length-measurable product 1, applies a marking 6 to a length-measurable product 1 having the defect 4, and includes the steps of detecting presence of a defect 4 in the length-measurable product, measuring a length of the length-measurable product 1 at least in one direction, and applying a marking to a predetermined marker area 5 in a length direction of the length-measurable product 1 having the defect 4, on the basis of positional information on the defect obtained in the defect detecting step and length measurement information obtained in the length measuring step.
A method for inspecting a length-measurable product, which during a process of manufacturing the length-measurable product whose length at least in one direction can be measured, when a defect occurs in the length-measurable product, applies a marking to a length-measurable product having the defect,
An inspection device for a length-measurable product, which in a manufacturing device for the length-measurable product whose length at least in one direction can be measured, when a defect occurs in the length-measurable product, applies a marking to a length-measurable product having the defect, the inspection device comprising:
