Publication number: 20040221700Abstract: In a web cutter where a blade is used to cut a continuous paper web into sheets, a tractor is used to move the web past the blade for cutting. The tractor operates in a start-and-stop cycle so that the web is temporarily stopped to allow the blade to lower and shear the web. The tractor accelerates in the next cycle to move another length of paper downstream from the blade. A high-speed cutter requires high acceleration of the tractor. This acceleration force causes the web to whip up uncontrollably, causing the web to break or wrinkle. To reduce the web breakage, a moving mechanism positioned upstream from the tractor and operate a second motion cycle is used to move the web toward the tractor such that a loop of paper is formed upstream of the tractor, thereby reducing the whipping action of the web.Type: ApplicationFiled: May 6, 2003Publication date: November 11, 2004Applicant: Pitney Bowes IncorporatedInventors: Daniel J.

Patent number: 5911807Abstract: Improvements are provided to improve an apparatus and method for processing a substantially constant velocity flow of a web of material, including a cutting mechanism and a web accumulator upstream of the cutter. The improvements include stopping the web by a side surface of the movable blade and configuring the accumulator dimensions and cutting speed to cause an appropriate level of force between the upstream severed end of the web and the blade. Several features achieve a low cutting time and modify cutting force to cut web regions with different characteristics, such as for cutting through splices. A low inertia rotary solenoid accelerates a blade through the web and against a resilient stop. The blade bounces off of the stop to its spring-biased home position. A permanent magnet or electromagnet holds the blade in the home position as solenoid current develops. These features result in reduced noise and shorter cutting time, thereby allowing an increase in web speed.Type: GrantFiled: December 23, 1996Date of Patent: June 15, 1999Assignee: Markem CorporationInventors: Jeffrey B.

Patent number: 5020403Abstract: A web feeding, cutting and dispensing machine includes a pneumatic cylinder for moving a hot wire to cut measured-length sheets from web stock. A pneumatic clamp cylinder moves a clamp bar for momentarily clamping the web during cutting. Upon pressing a start button, a pneumatic control valve sequentially operates the respective cutting and clamping cylinders for quickly retracting the hot wire, while more slowly retracting the clamp. Conversely, after the next measured web length has advanced, this control valve again sequentially operates these two cylinders in reverse order for quickly clamping while slower cutting. This dual control by one valve is advantageously achieved (1) by throttling air flow in retracting the clamp cylinder relative to retracting the cut cylinder, and conversely (2) by throttling air flow in advancing the cut cylinder relative to advancing the clamp cylinder.Type: GrantFiled: June 20, 1989Date of Patent: June 4, 1991Inventors: Joseph J.

Patent number: 4077289Abstract: A ribbon consisting of a series of interconnected labels is transported, first continuously and thereupon intermittently, along an elongated path toward a severing station where a movable knife separates successive foremost labels and the separated labels are engaged by pivotable suction heads which move the respective labels sideways into a different path for transport to a packing or other processing machine. That portion of the ribbon path which is located immediately ahead of the severing station extends along an arc of 180.degree., and the mechanism for intermittently transporting the ribbon has two pivotable deforming jaws which cooperate to deform the ribbon between successive labels whereupon a shoulder of one of the jaws engages the deformed portion and pushes the ribbon toward the severing station.Type: GrantFiled: November 18, 1976Date of Patent: March 7, 1978Assignee: Hauni Werke Korber & Co., KGInventor: Willy Rudszinat

Patent number: 4000672Abstract: A slitting machine is disclosed which feeds corrugated pipe through the machine intermittently and between the periods of pipe feeding when the pipe is stationary a plurality of angularly spaced saw sets are moved radially inward toward the machine axis and the pipe to cut slots through the wall thereof, and then withdrawn whereupon the cycle repeats. The pipe is fed through the machine by endless transporters equal in number to the saw sets and uniformly disposed angularly with respect to each other, the saw sets and the axis. The transporters have projections which fit into the corrugations of the pipe for a driving connection therewith. A saw set is located angularly between each pair of transporters so that a pair of the latter are roughly opposite to a saw set for an even number of sets or directly opposite a transporter for an odd number of sets.Type: GrantFiled: February 26, 1976Date of Patent: January 4, 1977Assignee: Altair National CorporationInventors: Theodor K. Sitterer, Siegfried Valentin

Patent number: 3970021Abstract: A series of shirt cuff pattern parts are placed in overlying relationship on a web of lining material and a conveyor belt engages the upper surfaces of the web of lining material and the pattern parts and holds the layers of material together as they are moved through a sewing machine. The overlying side edge of each of the pattern parts is folded down under an edge of the web of lining material, and the sewing machine sews through the folds. A predetermined range of lengths of the connected together series of partially completed shirt cuffs is continuously accumulated from the sewing machine, and are continually fed from the accumulation to a cutter, and are separated by cutting the web of lining material adjacent the trailing edge of a pattern part so that each partially completed shirt cuff is formed with a short length of the web of lining material protruding from the shirt cuff panel pattern part, and the pattern parts are stacked.Type: GrantFiled: July 3, 1974Date of Patent: July 20, 1976Assignee: Oxford Industries, Inc.Inventors: James L. Meadows, Donald H. Smith, Gordon H. Ellington, William O. Mitchell, W. Wade Frost
