An apparatus for detecting the correct timing of lot changing in a corrugator. The sum of a finished extent, which is the product of a specified cut length and the number of cut pieces excluding rejected cut pieces, and the residual quantity of a single-faced or double-faced corrugated board on the production line is subtracted from a lot size or length which is the product of the specified cut length and a specified number of cut pieces, to obtain a residual lot length, and this computation is successively performed at predetermined time intervals. The amount of raw material board fed is successively subtracted from the residual lot length, so that when the difference is reduced to zero, it is an indication of the desired lot changing timing. |
