MOTOR TRANSMISSION GROUP FOR TAPPATRIC TESTS FOR LIFE TAPES AND TAPPING MACHINE REQUIRED FROM SUCH MOTOR TRANSMISSION GROUP

摘要

The present invention concerns a motion transmission group for capping heads for screw caps. This group 1 comprises a device 10 for applying in use a predefined axial load to means of axial engagement P of the caps which a capping head T associated in use with said group is provided with. The device comprises at least one axially pre-loaded compression spring 12 so as to generate in use this predefined axial load. The device 10 is separable from the main structure of the transmission group 1 as a single body, with the aforesaid at least one spring maintained associated with a support structure 11 of the device in pre-loaded condition by means of two axial positioning portions 11b, 11c, to allow the replacement of the device with a structurally similar device, but suitable to generate in use a different axial load.
