Abstract
A device for grooving continuously-fed flat workpieces to form fold lines, including a slotted disc with a circumferential groove into which groove the circular edge of a grooving disc penetrates, which together with the slotted disc constitutes the grooving tool. A clamp rollers which runs off of a cylindrical section of the slotted disc prevents the free outer areas of the workpiece from being pulled into the operating grooving tool. In order to decrease structural expenditure, the clamp roller includes a cylindrical disc adjoining the grooving disc which rotates at the same rate of revolutions as the grooving disc.
