Abstract
Conventional heads for screwing bottle closures on to bottles generally are applied to the closure cap, while rotating at full speed which causes tipping of and damage to the closure cap. The invention seeks to overcome this disadvantage by a sleeve portion at the bottom of the fitting head first being applied without any torque to the closure cap, the sleeve portion being force-lockingly engaged with the rotating head only when the head is moved further downwardly through the clutch-engagement distance. When a maximum torque, which can be adjusted by means of a stressing spring, has been reached, the clutch begins to slip and the sleeve portion stops. The sleeve portion is of low mass so that after disengagement of the clutch, no additional torque due to inertia is applied to the closure cap.
