Abstract
A vulcanization mold () includes several segments () which define two end profiles () and two inner profile shells () having concave surfaces. With synchronous movement sequences, which take place via linear controls from both ends, the segments () are moved together under simultaneous shaping pressure. The outer profile shells () pass through twice the distance as the inner profile shells (). The forming of the work blank () is completed via the shaping pressure when the mold () has reached the closed position. Preferably the upper profile half shells () and the lower profile segments () are operatively connected to each other via toothed racks () and gear wheels () including additional sets of teeth (').
