PROBLEM TO BE SOLVED: To positively remove a foreign substance sticking to the surface of a sheet by forming grooves continuously running in the rotating direction on the outer peripheral part of paired cleaning rolls and arranging paired guides penetrating the grooves between both cleaning rolls And discharging the sheet to be cleaned, conducted by the guides. SOLUTION: A prepreg sheet 1 as a sheetlike material to be fabricated is fed into the nips between two pairs of cleaning rolls 42a-42d to remove a foreign substance such as fabrication dust sticking to the surface of the prepreg sheet 1, and the removed foreign substance is collected by sticking the substance with the help of two pairs of sticky sheet rolls 43a-43d. In this case, the prepreg sheet 1 is conducted buy each pair of upper and lower guides when the sheet 1 is fed into the nips between the cleaning rolls 42a-42d. In the region where the prepreg sheet 1 is guided at each of the cleaning rolls 42b, 42d, grooves 47 are formed and arranged mutually in a zigzag fashion. Thus it is possible to make the whole face of the prepreg sheet 1 come into contact with each of the cleaning rolls 42b, 42d.
