There is known a device in which a cutting means fixed to the base is operated and the timing is adjusted so that each plate is cut at the cut portion.

(Problem to be Solved by the Invention) However, in the conventional device, the dynamic kamaboko being conveyed is cut by a cutting means in a fixed state, so it is difficult to adjust the timing of cutting. However, if the timing is even slightly off due to mechanical play or electrical delays, there is a problem in that the weight of the product will fluctuate greatly due to deviations in the cutting position.

Further, since the timing error increases in proportion to the increase in the conveyance speed of the kamaboko with a board, this has also been a factor that inhibits the increase in cutting throughput.

Furthermore, since the dynamic kamaboko is cut by a static cutting means, there is a problem that the cut end is V-shaped and both end surfaces of the kamaboko are inclined.
