Abstract: The machine employs a rotary apparatus comprising a matrix-bearing cylinder coupled on an underlying transfer cylinder contacting over at least a tract of external surface thereof with an upper surface of a tile transiting on a rest plane. The tile is gripped between two facing branches of two lateral belts which advance the tile below the transfer cylinder; the rotation of the transfer cylinder being synchronized with the translation of the tile moved by the branches.

Abstract: The invention relates to a machine tool, in particular for the manufacturing, from sheet metal of mechanical parts such as pulleys, wheels and similar.It comprises a first chuckhead quill (4) rotatably mounted to a sturdy frame (1) and having coaxially and independently housed inside it a toolhead spindle (7) which can be commanded to slide in axial direction with respect to said quill (4). A second chuckhead quill (20) is exactly contra-positioned with respect to the first (4) and is rotatably mounted to a support element (18) which is slidably mobile in a direction parallel to its axis and which is slidably commanded by a powerful coaxial hydraulic jack (23). A second toolhead spindle (21) is coaxially disposed inside said second quill (20) with freedom to slide axially with respect to said quill (20).
