A tube compressing device in the frame is guided by the frame for compressing the tube from the end thereof to the area of the neck thereof. The tube compressing device moves the cover part in a manner whereby the cover part covers the opening of the neck of the tube when the tube compressing device is a maximum distance from the neck of the tube and the cover part frees the opening of the neck of the tube for the transfer of amorphous material when the tube compressing device is moved toward the neck of the tube.
