Abstract:
1. A molding jaw half for a corrugator for the production of transversely ribbed tubes, wherein the mold jaw half ( 10 ) has two mutually spaced end faces ( 12 ) arranged in a common plane and a semicylindrical base surface ( 14 ) which connects the two end faces ( 12 ) and to which there are releasably mounted molding insert elements ( 20 , 22 ) which are in the shape of a semicircular arc and which determine the outside surface of the transversely ribbed tube and which each have two diametrically oppositely disposed molding element end faces ( 28 ) which are in planar alignment with the end faces ( 12 ) of the mold jaw half ( 10 ), wherein each of the two end faces ( 12 ) of the mold jaw half ( 10 ), adjoining the semicylindrical base surface ( 14 ), have a number of first recesses ( 30 ), which corresponds to the number of molding insert elements, and the two molding element end faces ( 28 ) of the respective molding insert element, adjoining the two end faces ( 12 ) of the mold jaw half ( 10 ), are each provided with a respective second recess ( 32 ), wherein a fixing element ( 34 ) extends between the respective first recess and the associated second recess for fixing the respective molding insert element to the mold jaw half ( 10 ), wherein the semicylindrical base surface ( 14 ) of the mold jaw half ( 10 ) is provided with crests ( 16 ) and channels ( 18 ) which alternate in the axial direction, wherein first molding insert elements ( 20 ) having a convex cross-sectional edge contour ( 24 ) are releasably mounted to the crests ( 16 ) and second molding insert elements ( 22 ) having a concave cross-sectional edge contour ( 26 ) are releasably mounted in the channels ( 18 ), wherein the convex cross-sectional edge contours ( 24 ) of the first molding elements ( 25 ) and the concave cross-sectional edge contours ( 26 ) of the second molding insert elements ( 22 ) are directly and immediately steplessly adjoining each other.
