Abstract
The apparatus is of the type having a tensioning roller, a motor drive for rotating the roller in the direction of the band to tension the hooping band, and a locking device which may be raised or lowered by a thrust drive guided in a casing to press against the portions of the band to lock them together. The improvement comprises a control member associated with the motor drive of the tensioning roller. The position of the control member is determined on the one hand by a reaction force proportional to the tangential force exerted on the tensioning roller, and on the other hand by an opposing force acting on the control member. When the band tension exceeds a particular value, the motor drive of the roller is switched off by the control member and the thrust drive of the locking device is switched on.
