Patent number: 5195412Abstract: A cutoff system for exterior siding which includes a flying punch and shear. The system includes a main carriage which is adapted to reciprocate and, in one direction of travel, move at the same speed as the siding to be cut.

Patent number: 4979410Abstract: The invention is embodied in a tube cutting station in a tube producing mill. The cutting station includes a rotating press assembly and an axially moving cutting assembly. The cutting assembly is accelerated axially to a velocity which matches that of the tubing being produced.

Use of a lever arm pivoted to one of the die shoes in combination with a cam on the other die shoe optimizes horizontal movement of the notching blade relative to vertical movement of the die shoes. In a preferred form, the cutoff blade is passed through a slot in the notching blade holder. The die set can be used in apparatus where the tubing is intermittently supplied, or, as in a tubing mill, a continuous length of tubing is moved during the severing process.Type: GrantFiled: December 6, 1985Date of Patent: March 31, 1987Inventors: John F. Riera, John J. Pavelec, Billy J. Bielawski, Sr.

Patent number: 4648862Abstract: Apparatus is provided in which booklets of interleaved cigarette papers can be made from continuously moving strands of strip paper in which a cutting knife used to sever the paper strips precisely follows movement of the strip. Movement of a driven input shaft is brought onto the moving platform and used to operate the cutting knife. Paper from bobbins is converged by formers and a spreader into a strand advanced by nip rolls through a cutting station. The knife in the station cuts a booklet from the strand while the station moves with the strand. A driven rotatory shaft of non-circular section transmits its rotation to a sleeve that slides therealong as the station reciprocates relative to a shaft. The sleeve is operably connected e.g. by gearing or by a cam and follower to the knife so that rotation thereof brings about the cutting movement.Type: GrantFiled: June 17, 1985Date of Patent: March 10, 1987Assignee: Rizla LimitedInventor: Stanley G.

Patent number: 4643063Abstract: A tube cutoff machine for cutting a tube to precise lengths, which tube may be exiting from a tube mill at relatively high speeds. The tube cutoff machine includes a frame which supports a carriage for generally linear reciprocal movement parallel to the linear path of movement of the tube, the carriage in turn supporting a tube shearing apparatus. The carriage is reciprocated by a crank drive mechanism and additional connecting structure, which insures that the carriage will move at a constant linear speed for a duration of time sufficient to shear the tube as the carriage moves from a first location to a second location. The additional connecting structure includes a bell crank having an intermediate portion which is pivotally secured to the carriage, one end of the bell crank being secured to an end of a connecting rod of the crank drive mechanism, and the other end of the bell crank being provided with a cam follower which is caused to engage a stationary cam carried by the frame.Type: GrantFiled: August 1, 1985Date of Patent: February 17, 1987Assignee: McKenica Inc.Inventor: Eric W. Gobien

Patent number: 4621554Abstract: This invention concerns a flying shears (10) to shear rolled, extruded, drawn and/or like semi-finished products, the shears (10) being able to work on one or more rolled products at one and the same time and comprising support means (18) which are at least partially movable, blade-support means (21-121) able to move in a coordinated manner, means (23-24) to guide the movement of the blade-support means (21-121), and cam means (20) which actuate the blade-support means (21-121), in which flying shears (10) the support means (18) can move along a trajectory substantially parallel to the rolled product, and at least shaft means (19) of the cam means (20) are supported by the support means (18), and the shaft means (19) are spaced apart along an axis substantially perpendicular to the movement of the rolled product.Type: GrantFiled: November 27, 1984Date of Patent: November 11, 1986Assignee: Danieli & C. Officine Meccaniche SpAInventor: Alfredo Poloni

Patent number: 4614139Abstract: A cutoff apparatus for tubing and the like wherein a single electric motor is used to accelerate the apparatus into synchronous movement with the tubing and is also used to power the cutoff apparatus during the work stroke. A rotary crank is connected to the output shaft of the motor and to a control linkage which substantially reduces the cutoff work stroke length while at the same time preserving substantially the entire acceleration travel distance.Type: GrantFiled: July 12, 1985Date of Patent: September 30, 1986Assignee: Alpha Industries, Inc.Inventor: Alexander Borzym

Patent number: 4542670Abstract: A flying cutoff system for tubing and the like wherein a cutting die mechanism (46) is driven by a threadless shaft (36) and traveler assembly (44) powered by a reversible DC motor (40). Die set position relative to the press is accurately monitored even in the presence of slip in the drive.Type: GrantFiled: May 27, 1983Date of Patent: September 24, 1985Inventor: John J. Borzym

Patent number: 4523500Abstract: A method and apparatus for cutting a continuous corrugated member while conveying it in a longitudinal direction thereof, in which a movable cutter blade is moved forward in the same direction as the conveying direction of the corrugated member at the same speed as the conveying speed of the corrugated member. The cutter blade is also reciprocated to cut the corrugated member when the cutter blade is moved forward.Type: GrantFiled: April 14, 1983Date of Patent: June 18, 1985Assignee: Nippondenso Co., Ltd.Inventor: Kimio Maruyama

Patent number: 4497230Abstract: A shear having a main frame with a horizontal shaft and a shear frame pivotally attached to the shaft for adjustment relative to the main frame. The shear frame includes a pair of spaced members and a king pin is rotatably supported on the spaced members. A master shearing arm is nonrotatably mounted on the king pin and a subordinate shearing arm is rotatably mounted on the king pin and a cutting knife is carried on each shearing arm. The master shearing arm and the subordinate shearing arm are connected by a hydraulic cylinder and a piston rod to move the shearing arms between an open position and a closed position to cut workpieces passing between the cutting knives.Type: GrantFiled: April 21, 1982Date of Patent: February 5, 1985Inventor: D. Leet Shields

Patent number: 4471641Abstract: A machine for continuously punching, shearing and forming sheet material comprises a frame and punching, shearing, and forming stations. Rollers are provided for continuously feeding sheet material through the stations. A cam periodically engages the tools of the respective punching and shearing stations to actuate the respective punching and shearing operations and simultaneously to advance the respective punching and shearing stations in unison with the direction of feed of the sheet material. The forming station includes adjustable rollers which permit adjustment of the space between the rollers. The method of the present invention comprises continuously feeding the sheet material through the punching, shearing, and forming stations. At the punching and shearing stations, the tools for punching and shearing the sheet material move in unison with the sheet material during the time that they are performing their punching and shearing operations, respectively.Type: GrantFiled: November 15, 1982Date of Patent: September 18, 1984Inventor: James L. Mitchell

Patent number: 4462290Abstract: A tube cut-off unit is arranged at the downstream end of a tube mill and is powered by a drive unit mechanically driven by the main shaft of the mill which drives the tube forming rolls. The drive unit mechanically rotates a crank which, through a link, reciprocates a slide along the path of travel of the tube. A tube cut-off blade on the slide is cam actuated to sever the tube. Means are provided to insure that the slide is moving at a constant speed and at the same speed as the tube when the tube is being severed.Type: GrantFiled: October 27, 1982Date of Patent: July 31, 1984Inventor: Bernard J.
