Abstract: Apparatus for replacing spent and/or damaged knives with fresh knives in a machine wherein semifinished rod-shaped smokers' products are converted into cigarettes, filter mouthpieces or the like employs a knife holder, a locking device which can releasably clamp a knife in the holder, a preferably automated system for temporarily deactivating the locking device in order to allow for removal of a spent knife, and a conveyor system for introduction of a fresh knife into the holder subsequent to removal of the spent knife and prior to renewed activation of the locking device.

Abstract: The invention relates to a liquid cooling system for machine components of production machines of the tobacco-processing industry. The object of the described cooling system is to improve the conveyance of liquid, both in terms of structure and function. This object is accomplished by dividing the liquid cooling system, which is embodied as a closed system, into at least two liquid loops (13, 17). The advantage that can be attained with the new liquid cooling system is that the liquid loops can be adapted to one another such that the temperature and output of the consumers match. The pipe cross-sections and pumps can therefore be kept small.
