Apparatus for producing a metal grid reinforcement and machine

A machine having a driven, rotatable main wheel for receiving multiple longitudinal profiles, and having an apparatus for producing a metal mesh reinforcement from multiple metal profiles, comprising multiple longitudinal profiles and one winding profile, wherein the apparatus comprises a welding unit for welding a longitudinal profile to the winding profile at a connecting point of the two metal profiles and a winding profile guide that conducts the winding profile, which can be guided up to the winding profile guide from a master coil of the winding profile, to the welding unit, wherein the winding profile guide has a contact side and a positioning side, wherein the contact side and the positioning side can be moved relative to one another, and wherein the contact side and the positioning side are matched to one another in such a way that a winding profile guided up between the contact side and the positioning side is forced into a centered position when the positioning side and the contact side are moved toward one another, wherein the positioning side has a depression which is matched to the winding profile and into which a longitudinal portion of a centered winding profile dips, and wherein the contact side comprises a flat, displaceable slide strip.
