Patent number: 4799414Abstract: A variable rotary cutter assembly for transverse cutting of web material as it passes through a nip between rotating anvil and knife cylinders includes one or more cutter assemblies selectively positionable on the periphery of the knife cylinder. Each cutter assembly includes a base block adapted to be releasibly mounted on the knife cylinder, and a pair of pivotally connected block members one of which is adapted for releasibly mounting on an associated base block and the other of which carries an elongated knife blade and is outwardly pivotable about a pivot axis parallel to and spaced from the knife blade. Spring means bias the knife carrier block member outwardly about its pivot axis so as to effect a predetermined cutting pressure per unit length of the knife blade against the anvil while enabling self-adjusting movement of the knife blade to accommodate substantial variance in anvil and knife cylinder spacing and knife blade wear.Type: GrantFiled: November 16, 1987Date of Patent: January 24, 1989Assignee: Scheffer, Inc.Inventors: Bruce A. Scheffer, Eric K. Lo

Patent number: 4785697Abstract: The invention refers to an apparatus for dividing a continuous web of material into successive single sections, particularly for dividing a web of covering material into successive single bands used in the manufacturing of filter-tipped cigarettes. Such an apparatus comprises a rotary cutting roller with one or more peripheral radial knives which are angularly spaced apart from each other and have their cutting edge parallel to the axis of rotation of the cutting roller. According to the invention, each knife is secured to a knife holder consisting of a bridge-like member having an inherent elastic compressibility in the radial direction, which in the fashion of a beam with a plurality of supports is supported by the cutting roller on two end supports and on one or more intermediate supports. The supports are preferably adjustable in the radial direction, and particularly consist of wedges.Type: GrantFiled: April 30, 1987Date of Patent: November 22, 1988Assignee: Sasib S.p.A.Inventor: Gian L. Gherardi

Patent number: 4785832Abstract: A device for dividing a continuous web of wrapping material into successive single sections of the same length, particularly for dividing a web of wrapping material into successive single bands used in the manufacture of filter-tipped cigarettes. The device includes a rotary cutting roller with one or more angularly equispaced peripheral radial blades, the cutting edge of which is parallel to the axis of a shaft for driving in rotation the said cutting roller (1). The blade or blades are each secured to a bridge-shaped blade-carrying member which by elastic deformation is elastically yieldable in the radial direction and can be completely or partly made from the skirt of the cutting roller fastened to the roller or from a block added and secured to the skirt.Type: GrantFiled: October 8, 1986Date of Patent: November 22, 1988Assignee: SASIB S.p.A.Inventors: Gian L. Gherardi, Valter Spada

Patent number: 4771665Abstract: A blade quality monitor for use with cutter reels having specifically identifiable blades utilize a sensor to detect the position of a physical anomaly on the reel. Additional sensors sense the force at the interface between the cutter reel, the material wrapped thereon and the associated pressure roller. The position of the physical anomaly is correlated with the sensed force to determine the magnitude thereof at each blade which is indicative of the condition of the blade with respect to sharpness or intactness.Type: GrantFiled: August 28, 1987Date of Patent: September 20, 1988Assignee: Lummus Industries, Inc.Inventors: Donald W. Van Doorn, William D. Beeland

Patent number: 4770078Abstract: An apparatus for scoring or cutting has a generally stationary frame, a lower cradle in the frame, and a plurality of lower rollers rotatable in the cradle about respective roller axes and all tangent to an imaginary lower cylinder centered on a lower axis. A lower arbor centered on the lower axis has one end projecting into and supported by a lower journal in the frame and an opposite unsupported end. A lower tube is fitted snugly on the lower arbor and has an outer surface lying on the lower cylinder and resting on the lower rollers. Similarly, an upper pressure plate in the frame carries a plurality of upper rollers rotatable in the pressure plate about respective axes and all tangent to an imaginary upper cylinder centered on an upper axis. An upper arbor centered on the upper axis has one end projecting into and supported by an upper journal in the frame and an opposite unsupported end.Type: GrantFiled: March 13, 1987Date of Patent: September 13, 1988Inventor: Jean Gautier

Patent number: 4732067Abstract: A veneer clipper of rotary type is disclosed wherein a cutting knife carried by an intermittently rotatable knife carrage roll cuts through a veneer sheet moving past an anvil roll. The clipper has a plurality rotatable back-up rolls which are movable reciprocally toward and away from the carriage roll. In their operative position, the back-up rolls are pressed against the circumferential surface of the carriage roll for bracing the same to counteract the reactional pressure exerted by the anvil roll during veneer cutting. There is provided means for driving reciprocally the back-up rolls in conjunction with the intermittent rotation of the knife carriage in such a way that the back-up rolls may be kept in pressing contact with the knife carriage roll at least while the veneer sheet is being cut by the knife and then moved away from the surface after each such cut.Type: GrantFiled: February 5, 1987Date of Patent: March 22, 1988Assignee: Meinan Machinery Works, Inc.Inventor: Yoshiaki Yamada

Patent number: 4699033Abstract: The invention refers to the devices for dividing a continuous web of wrapping material into successive single sections of a same length. These devices comprise a rotary cutting roller (1) with one or more angularly equispaced peripheral radial blades (7), the cutting edge of which is parallel to the axis of shaft (6) for driving in rotation the said cutting roller (1), and a rotary counter-roller (19) having one or more peripheral anvils (18) that cooperate each with a blade (7) on the cutting roller (1). According to the invention, the blade or blades (7) are each secured to a projecting blade-carrying member (8) which by elastic deformation is elastically yieldable in the radial direction toward the axis of shaft (6) for driving in rotation the cutting roller (1).Type: GrantFiled: March 24, 1986Date of Patent: October 13, 1987Assignee: Sasib S.p.A.Inventor: Gian L.

Patent number: 4678128Abstract: A fiber-bale mill comprises a cutting device which is movable over a row of fiber bales. A collector passage is open on top below the cutting device which travels to and fro. An air passage in a cutting device through which the cut fibers are drawn from the vicinity of the cutting mechanism communicates with the passage. A cover strip at least partially covers the top of the collector passage to maintain a reduced pressure therein. Guide rollers for the cover strip are provided on the cutting device, to lift the cover strip from the collector passage at the location, at which the air passage opens into the collector passage and guide the cover strip over the portion of the air passage opening into the collector passage.Type: GrantFiled: January 24, 1986Date of Patent: July 7, 1987Inventor: Hubert A.
