Apparatus for the moving-along tool positioning of linearly conveyed articles, comprising a conveyor device forming a conveying line for conveying the articles in a conveying direction and having a plurality of receiving elements adapted to hold the articles, a processing station arranged along the conveying line and having at least one processing tool adapted to process the articles, wherein the processing station has a positioning unit adapted to position the at least one processing tool, wherein the positioning unit is formed by a longitudinal slide, which is slidable in the conveying direction relative to a carrier element, and a transverse slide, which is arranged on the longitudinal slide so as to be slidable transverse to the conveying direction, wherein the longitudinal slide is driven in an oscillating manner such that the longitudinal slide on the one hand, in a work cycle, moves along synchronously with the receiving elements in the conveying direction from a starting position into an end position and on the other hand, in a return cycle, moves contrary to the conveying direction from the end position back into the starting position, and wherein the transverse slide has at least one guiding element which engages into a stationarily arranged link guide, wherein the link guide on the one hand is adapted, during the work cycle, to move the transverse slide transverse to the conveying direction towards the receiving elements from a standby position into a working position and from the working position back into the standby position, and on the other hand is configured, during the return cycle, to guide the transverse slide transverse to the conveying direction without deflection. a conveyor device forming a conveying line for conveying the articles in a conveying direction and having a plurality of receiving elements adapted to hold the articles, a processing station arranged along the conveying line and having at least one processing tool adapted to process the articles, wherein the processing station has a positioning unit adapted to position the at least one processing tool, wherein the positioning unit is formed by a longitudinal slide, which is slidable in the conveying direction relative to a carrier element, and a transverse slide, which is arranged on the longitudinal slide so as to be slidable transverse to the conveying direction, wherein the longitudinal slide is driven in an oscillating manner such that the longitudinal slide on the one hand, in a work cycle, moves along synchronously with the receiving elements in the conveying direction from a starting position into an end position and on the other hand, in a return cycle, moves contrary to the conveying direction from the end position back into the starting position, and wherein the transverse slide has at least one guiding element which engages into a stationarily arranged link guide, wherein the link guide on the one hand is adapted, during the work cycle, to move the transverse slide transverse to the conveying direction towards the receiving elements from a standby position into a working position and from the working position back into the standby position, and on the other hand is configured, during the return cycle, to guide the transverse slide transverse to the conveying direction without deflection.
