ABSTRACT:
The present specification describes and claims a device for severing a strip which interconnects items conveyed one behind the other and spaced apart from each other. The device is particularly suited to cutting the binding strip for the spine of books, blocks etc. The device comprises a knife mechanically coupled to a follower device which, in use, follows the profile of the individual items. The follower device maintains the knife in a position ready to cut and when the follower device drops down a gap between adjacent items, the movement of the knife activates control means to operate a knife power drive, the knife then cutting the strip and following a working cycle back to a ready position wherein the follower device can engage a subsequent item.
