Abstract (en)
[origin: EP3248706A1] Rolling machine (1) for making impressions on cylindrical bodies, which comprises a support structure (2) mechanically connected to two or more forming rollers (6), each fit on a respective rotary transmission member (21) and provided with a shaped profile susceptible of rotating on a cylindrical body to be formed, placeable along a central work axis (A) of the machine (1). The machine (1) also comprises two or more hydraulic actuators (15), each of which mechanically associated with the support structure (2) and rotatably supporting a corresponding rotary transmission member (21) in order to move the forming roller (6) along a respective first transverse axis (R) perpendicular to the central work axis (A), and comprises two or more motors (16), each of which mechanically connected to a corresponding rotary transmission member (21) in order to actuate the corresponding forming roller (6) in rotation around the rotation axis (Z) thereof. In particular, such rolling machine (1) comprises two or more actuator means (22), each mechanically associated with a corresponding rotary transmission member (21) in order to move the latter between a forward position, in which it is fit with the relative forming roller (6), supporting it on the corresponding hydraulic actuator (15), and a retracted position, in which it is removed and free from said relative forming roller (6). In addition, each rotary transmission member (21) is telescopically extensible in order to compensate for the movement between the forward and retracted positions.
