Apparatus for conveying a paper web or other sheet material pneumatically along a predetermined path comprises two guide plates 20, 22 having outer surfaces defining successive parts of the path and having adjacent edges which are inclined to the outer surfaces and are spaced apart so as to form a slot 28 inclined to the outer surfaces of the plates, and including an air pressure manifold 26 which is secured to both guide plates and from which an air stream is arranged to be emitted through the slot to produce an air stream which will move along one of the plates 22 which is downstream of the other plate with respect to the intended direction of conveyance of the web or other sheet material. When applied to a cigarette making machine, apparatus of this general type may be used at various positions for feeding the paper web through the printer, and also to feed the web automatically all the way into the garniture 12.
