Abstract: A flying saw apparatus for severing a predetermined length of material from a continuously moving length of material is disclosed. A saw carriage is supported on a main frame assembly for reciprocating motion parallel to the direction of motion of the material. The saw carriage includes a saw bridge which extends transversely of the direction of motion of the saw carriage and is movable upwardly and downwardly. A saw shuttle, which carries a circular saw, is supported for reciprocating motion on the saw bridge. The saw carriage is connected through a drive mechanism to the main power drive of the material conveyor preceding the flying saw apparatus. The reciprocating motion of the saw carriage is transferred to reciprocating transverse motion of the saw shuttle by a rack and pinion mechanism.

Abstract: A flying cutoff for cutting successive lengths of a continuously moving, elongate workpiece includes a carriage assembly provided with a cutoff die set which is slideably mounted on a swinging ram and is selectively accelerated or decelerated in synchronism with the movement of the workpiece by a belt drive system which includes a plurality of endless, flexible, toothed belts, each secured to the carriage assembly and trained around a corresponding drive and idler gear. The belts are of different pitches and/or tensions so as to give the belts differing resonant and harmonic frequencies which tend to cancel each other out in order to eliminate cutting measurement error created by the cumulative effects of belt oscillation. The drive gears are driven by a hydraulic motor whose output is precisely controlled by a direct current, reversible stepping motor.

Abstract: A ram driven tube cutting apparatus of the double cut type in which sections of tubing are successively severed from a continuous length thereof by a notching cut followed by a severing cut, includes improved mechanism for clamping the tubing during the cutting process. A pair of opposed, complemental die jaws are mounted on slides controlled by spaced cam followers carried by the slides. A reciprocating wedge cam engages and forces the cam followers apart to move the slides thereby closing the jaws on the tubing. One of the cam followers comprises a roller mounted on an eccentric shaft which may be selectively rotated to adjust the clearance between the die jaws. The other cam follower is spring loaded toward the cam within a slide mounting provided in its slide and automatically shifts to an overload position to avoid damage to the mechanism when foreign objects become lodged between the die jaws.

The apparatus includes a chassis that is mounted for limited movement in the direction of web travel. The chassis includes a clamping plate and a base plate which are selectively brought into clamping engagement with the web, which enables the chassis to be moved along with the web. Subsequently, a tool is drawn into engagement with the web to perform the work operation. Upon completion of the work operation, the tool is removed from the vicinity of the web, the web is released by the chassis clamping and base plates, and the chassis is returned to its original position.

Abstract: A flying ram cutoff machine for severing successive lengths of an elongated workpiece continuously moving in the direction of its longitudinal axis employs a bevel gear drive for swinging a ram in synchronization with movement of the workpiece. A motor drive fly wheel and clutch assembly power a drive shaft which extends parallel to the longitudinal axis of the workpiece, at the rear of the machine. A pair of bevel gears disposed at spaced locations along the drive shaft form power take-offs for transmitting power from the drive shaft to a pair of input shafts which extend perpendicularly away from the drive shaft and toward the swingable ram. A pair of crank assemblies couple the input shafts with the ram to produce swinging movement of the ram upon rotation of the drive shaft. Backlash of the drive system is controlled by interposing a stabilizing spacer between one of the bevel gears and a stationary support.

Abstract: A process and apparatus for the continuous shearing of billets or bars of various shapes and sizes produced in a continuous casting plant wherein the shearing device moves in harmony with the billets is described. According to the process and as permitted by the apparatus, a first blade preferably the upper blade is caused to approach a billet and rest on it by means of hydraulic pressure working on cylinder/piston means, and thereafter a second blade positioned opposite the first blade is caused to move from supporting brackets to approach the billet and thereafter the blade caused to continue its course and cut into and shear the billet with the shears being supported substantially only by the billet during the shearing process. The device is relatively simple in design and is highly efficient.

The filaments move alternately toward and away from the carriage to cut the web during successive synchronized movements of the carriage and web. Further, the filaments may be horizontally moved to cut profiles other than straight, vertical sections in the separate lengths of the web.

Abstract: A cut-off die set is disclosed for use in a cut-off apparatus of the type in which continuous length of tubing or other elongated stock emanating from a tubing mill is severed into lengths as the tubing emanates from the tubing mill by means of a cut-off die set mounted within the cut-off apparatus. The cut-off die set is adapted to be clamped to the tube so as to move therewith during severing of the tubing by a ram operated cut-off blade descending vertically to shear the tubing. The present disclosure involves a improvement to a notching mechanism often included in such cut-off apparatus in which a horizontally reciprocated blade notches the upper portion of the tubing just prior to severing by the main cut-off blade so as to eliminate dimples in the severed tube cross section.

Abstract: A compact machine for measuring, cutting and applying insulation blanket material onto sheet metal workpieces as they flow along a conveyorized lower line. The blanket material flows along an upper path. A flying shear mechanism, which travels a short distance along this path, is driven downstream when the trailing edge of a workpiece is sensed. Rack and sector mechanism brings the shear to an incisive stop at its downstream cutting position when the shear blade strikes its cutting block; hence the kinetic energy of the downstream movement is utilized for shearing. The shear remains in downstream position, to serve as a gage for starting the blanket material, until a sensor in the lower flow path senses the leading edge of the next sheet metal workpiece; this raises the shear blade and moves the shear mechanism to upstream position. A pneumatic system accurately times the cut-off mechanism to match the shearing of the blanket material to the length of the workpiece, leaving a margin if desired.

Abstract: A device for cutting to length, by shearing, articles known in the sheet metal and air conditioning art as hollow vanes. The device includes a wedge shaped cutting element, means for determining the length of vane to be sheared and a clamping element arranged adjacent the shearing blade to positively hold the vane after the length has been properly determined for shearing. The device is automatically controlled to provide length detection, clamping and shearing in proper sequence in coordination with a vane producing machine with control means provided to establish the recycling of the machine after a length of vane has been cut and has been delivered from the device. The clamping device provides a means for insuring continued flow of the vane through the die portion of the device and a sensing element is provided for retraction of the device after the shearing such that the sheared vane is free to fall from the device and not inhibit further flow of the vane through the device.

Abstract: Continuously cast plastic strip has interspaced marks or defects with lengths of unmarked usable strip therebetween. To obtain a maximum possible yield of sheets from such strip, the lengths of the portions between the marks or defects are measured and cut into sheets of two or more different lengths, the cutting being such as to produce the maximum yield of sheets of either or all lengths, singly or in combination, which can be obtained from the length cut. This procedure reduces the loss or waste due to the marks or defects, to a minimum. A special system is provided for this practice and for cutting out the marks or defects between the unmarked strip portions free from defects, with a minimum of loss or waste. Other features are involved.
