Abstract

A flexible sheet (e.g. of cellular material used for automobile upholstering) is advanced pref. horizontally beneath a cutter wheel to produce a groove in the upper face of the sheet, the cutter wheel being rotated at such that its cutting region moves in a direction opposite to that of the advance direction of the sheet. A curved retaining plate surrounds the edge of the cutter wheel at the region where the cutter wheel leaves the sheet and the lower edge of the retaining plate in very close (pref. touches) the upper face of the sheet. Pref. the retaining plate extends upwardly to the height of the rotational axis of the cutter wheel whereby dust is directed upwardly into a suction hood. Pref. the sheet is advanced by drive rollers contacting the upper face of the sheet, one of the drive rollers being adjacent the retaining plate. The sheet doesn't deform thereby ensuring straight accurately cut grooves.
