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.
Claims13
A device for severing a strip which interconnects items conveyed one behind the other and spaced apart from each other, particularly a binding strip for the spine of books, blocks or the like, said device comprising:
- a follower device for following the profile of the items;
- a knife, the follower device mounted for movement together with the knife, the follower device being arranged to maintain the knife in a first position, under a force urging the knife towards a cutting position;
- an externally energized knife drive for powerfully moving the knife through the cutting position;
- and,
- switching means for the knife drive, actuated by an initial movement of the knife due to the follower device detecting a gap between adjacent items.
