A processing head (14) is provided that is axially insertable in the tyre (3) retained by a support group (15). The processing head (14) comprises at least one or more radially extendable arms (20), having each a proximal end (20a) that is constrained with respect to the processing head (14) and a distal end (20b) carrying at least one pressing element (21). Driving devices (22) operate on each arm (20) in order to move it between a rest position in which the pressing element (21) is moved close to the geometric rotation axis (X) and a work position in which the pressing element (21) is moved away from the geometric rotation axis (X) in order to exert a thrust action towards a radially inner surface (3a) of the tyre (3). A movement group (16) provides for mutually moving the processing head (14) and the tyre (3) around and along a geometric rotation axis (X), in order to complete the application of a semi-finished product (2) by the pressing elements (21).
