Abstract: A cutting device for the chipless cutting of a material comprises a cutting part and a supporting part. The cutting part and the supporting part are designed to be rotated with respect to one another about an axis of rotation between an open position and a closed position. A hand lever is articulated to the supporting part for pivoting about a pivot axis. A ratchet mechanism converts a back-and-forth motion of the hand lever into a continuous rotational motion of the cutting part toward the closed position. The ratchet mechanism includes a toothing and a drive pawl, which can be brought into an effective position with respect to the toothing. Furthermore, the cutting device comprises a coupling mechanism, which converts a one-time pivoting motion of the hand lever into a rotational motion of the cutting part. A separate coupling element transmits force from the hand lever to the cutting part.

Abstract: An advancing unit for a cleaning spiral, which can be rotated by a motor about its longitudinal axis, of a pipe cleaning machine, such as, for example, a pipe cleaning machine having a drum. The advancing unit includes a drive device, which produces the advancement of the cleaning spiral, with at least two clamping parts, wherein at least one clamping part thereof can be brought into a clamping position against the cleaning spiral in such a manner that the clamping parts press against the cleaning spiral, so that an advancement of the cleaning spiral is generated in the case of a rotating cleaning spiral. The advancing unit further comprises a control device for controlling the advancement of the cleaning spiral by means of at least one of the clamping parts as well as a safety device, by which at least one of the clamping parts can be brought out of its clamping position against the cleaning spiral. It is provided that the control device and the drive device and/or the safety device can be actuated by means of a common handle part. The invention further relates to a pipe cleaning machine, in particular a pipe cleaning machine having a drum, and to a method for operating a pipe cleaning machine.
