A tyre molding press having a fixed bed and a cross-piece, which crosspiece is designed to travel, by virtue of a crank mechanism, along vertical guides formed partly along the uprights and partly along extensions of the same; the guide portions extending along the upright extensions enabling extra vertical travel of the crosspiece, and each being limited at the rear by a switch element which may be operated selectively for opening the respective guide at the rear and enabling the big end of the respective connecting rod to slide backwards, with the crank fixed, and along an end surface of the respective upright, in such a manner as to tilt back the crosspiece. |
