Method and device for guiding a tool

A device for guiding a tool in a repetitive action on a moving product, wherein the device comprises a cross guide, wherein the tool is held on a Z-slide, the guidance of which defines the Z-axis of the cross guide, wherein the Z-slide is movably held on an X-slide, the guidance of which defines the X-axis, which is perpendicular to the Z-axis, wherein the guidance along the X-axis is mounted in a base plane,

• wherein
• an X-drive is provided to drive the X-slide,
• for the drive of the Z-slide, a Z-drive is held in the base plane in a stationary manner, said Z-drive comprising a belt driven by a first servomotor provided for the drive of the Z-slide, wherein the belt is guided in a T-shaped path, which has an X-leg and a Z-leg, wherein the X-leg extends around two pulleys held in the base plane and forms a top pull and a bottom pull, wherein the top pull branches via a first tension roller and a second tension roller held on the Z-slide into a loop forming the Z-leg, said loop being guided around another redirection roller, which is held on the X-slide at the end of the Z-section, wherein a compensation device is provided for controlling the first servomotor provided for the drive of the Z-slide so as to compensate for a movement of the Z-slide caused by a movement of the X-slide.
