Feeder screw for feeding of objects, such as glass bottles 2, between the screw 5 and a support 70 disposed around it at the side thereof: The feeding screw 5 is hollow and a rotatable driving shaft 65 for rotation of the screw runs through it. The driving shaft is articulated and connected with the screw 5 at one end thereof. Elements 67,68,69 are further disposed for rotating the screw 5 relative to the driving shaft 65 and locking the screw in the desired position relative to said shaft. This is achieved in that the driving shaft 65 is connected with the feed screw 5 via a ball-and-socket joint 66 which for the purpose of rotation is fixed to both the driving shaft and the feed screw. <IMAGE> |
