Abstract: A running web of tipping paper in a filter tipping machine is attracted to the peripheral surface of a rotary suction conveyor constituting a counterknife for a set of equidistant knives which are radially movably mounted in axially parallel grooves of a rotary knife carrier. Each knife is adjustable radially of the carrier by a discrete first adjusting device, and all of the knives are adjustable simultaneously by a common adjusting device having a support movable axially of the carrier and mounting all of the first adjusting devices. Simultaneous radial adjustment of all of the knives by the common adjusting device is effected after certain periods of use and attendant wear upon the cutting edges of the knives.

Abstract: The knife is normally clamped tightly against a supporting arm by a retaining bolt, but when the bolt is sufficiently loosened, the bolt itself and the knife through which it passes may be forced radially inwardly or outwardly by shifting a transversely reciprocable slide plate in the appropriate direction along its path of travel. An oblique slot in the slide plate receives the bolt and pushes it in the selected adjusting direction as the slot is displaced transversely by shifting of the plate. A pair of counter-acting set screws serve as means for shifting the plate and for releasably retaining the same in a selected position. A long key on the slide plate slidably fits into a mating key way on the supporting arm to guide the plate in its transverse movement, and because the key extends transversely of the path of in-and-out adjusting travel of the knife, it helps absorb and resist radial loading on the knife which occurs during the cutting operation.

Abstract: Apparatus for severing the running web of tipping paper in a filter tipping machine has a rotary anvil whose cylindrical peripheral surface is contacted by the running web, a rotary carrier which is adjacent to and defines with the anvil a nip for the running web, a knife which is movably mounted in the carrier and has an elongated cutting edge which cooperates with the web-contacting portion of the peripheral surface of the anvil to sever the web once during each revolution of the carrier, and a system of springs which bias the knife axially of the carrier so as to prevent movements of the knife under the action of centrifugal force and/or gravity but to allow the knife to move its cutting edge into a position in which the entire cutting edge contacts the peripheral surface of the anvil upon completion of the first cut. This reduces noise which is generated when the apparatus is in use.

Abstract: Apparatus for moving the knives relative to their rotary holder in a tobacco cutting machine has a crankshaft which is rotatable and is rotated once during several successive revolutions of the holder. The crankshaft is the input element of a step-down transmission whose output element is a ring gear meshing with pinions for transmission of motion to discrete displacing units, one for each knife. The ring gear is rotated at intervals by a gear which is coaxial with a freewheel. The latter is rocked back and forth by a lever which is pivoted by the crank pin of the crankshaft by way of a rod-like connector. One end portion of the connector is coupled to the lever by an adjusting device which can change the extent of pivotal movement of the lever and hence the extent of rotation of the ring gear whenever the lever is pivoted in one of two directions.

Abstract: The knives of a rotary cutter assembly are mounted on a centrally disposed pivot and elastic means are used to apply bias force to the knife ends to normally maintain the cutting edges of the knives substantially parallel with the axis about which the rotary cutter assembly rotates, the mounting being such to allow the knives to pivot when contacting the surface of a rotary drum against which they operate to assure that the cutting edges are parallel to the drum surface during the actual cutting through of a material web passing in a winding course on the drum. Additionally, means for adjusting the radial positioning of the pivots relatively of the said cutter assembly axis of rotation are included and means for locking the pivots in a particular position are also included.

The drive of the rotating elements is effected through the use of a timing belt operating from the main drive of the machine on which the cutting mechanism is mounted.

Abstract: In a tobacco cutting machine where tobacco is cut by knives mounted on a rotating drum, the knives are advanced as they are worn away. In order to prevent the knives being advanced too far, and becoming damaged by contact with other machine parts, a safety device is provided. This includes a blade positioned near the path of the knife edges to be struck by a knife if the latter is advanced too far. The resultant movement of the blade is amplified by a lever system and is used to trigger a microswitch in the cutter drum drive circuit, whereby when a knife is advanced too far the cutter drum is stopped. The advancing mechanism for the knives includes a ratchet device driven by pulses of compressed air via a piston and cylinder device.
