Claims

[Scope of utility model registration request]

In a scrap winding device that winds long selvedges of band steel produced by a side trimming device into a pincushion shape with a mandrel that is guided and rotated by a scrap chute, holes are formed in the width direction on the guide surface of the scrap chute. a light source that passes light across the entire width of the elongated hole, a photodetector that detects the amount of light emitted from the light source through the elongated hole, and a light amount signal detected by the photodetector. A scrap amount detecting device for a scrap shoot, comprising a signal processing device for determining at least one of a change in amount and a change in position of the long ear waste on the scrap shoot.
