Abstract
Screwing and rolling head for the application of pre-threaded caps on containers, comprising a first support, designed to be moved with a helical motion, a second support, which is mobile with respect to the first support in a longitudinal direction and is fixed in rotation with respect to the first support, a device for screwing caps, fixed in an axial direction with respect to the second support and rotatable with respect to the second support, a torque-limiter device, connected between the screwing device and the second support, and at least one oscillating arm, which carries a rolling element and is articulated to the second support about a transverse axis. The device for screwing caps comprises a gripper, which is mobile between an open position and a closed position and is designed to grip a cap along a side wall thereof, the movements of opening and closing of the gripper being controlled by a control rod, which is mobile in an axial direction.
