Abstract
A cutoff for cigarette rods or the like has a rotary carrier for one or more reels of convoluted metallic band material constituting the knife or knives which sever the rod at regular intervals when the carrier rotates. The reels can be rotated in a direction to pay out the band material, and the leaders of the bands extend from the carrier and orbit along a path which is traversed by the rod. The leaders are ground at the rate at which the reels are rotated so that the length of that portion of each band which extends from the carrier remains constant. One marginal portion of each band constitutes the cutting edge, and such cutting edges need not be sharpened while the cutoff is in use because rotation of the reels results in movement of fresh portions of cutting edges to severing positions. The leaders of the bands are caused to extend through adjustable chucks with cheeks flanking the leaders to reduce the likelihood of undesirable deformation of flexible leaders during severing of the rod and/or in response to rotation of the carrier at a high speed.
