Abstract: The disclosure of the present invention relates to a torque and mass compensating counterweight system employed with the drive of a cold pilger rolling mill. The counterweight is connected directly to the crank by a sliding block, displaceable in a slot provided in the counterweight, in which the counterweight is arranged to reciprocate 90.degree. out of phase with the crank and is arranged in guides to move in a plane parallel to the direction of movement of the mill.

Abstract: The disclosure of this invention pertains to a solid construction for a bedplate used in a stand of a rolling mill. The bedplate is characterized by having a uniform cross section throughout its length wherein a groove for supporting a housing is easily formed and adapted to receive a filler element, such as a wedge, for anchoring the housing to the bedplate.

Abstract: The disclosure pertains to an arrangement for cooling a heated workpiece, such as, strip or slab as it issues from a rolling mill or continuous slab caster. The longitudinally moving workpiece is caused to pass between a number of coolant discharge headers arranged above and below the workpiece in which, during its cooling, the coolig rates of the upper and lower surfaces of the workpiece differ. The effective discharge of the headers is varied to equalize the cooling rates of the upper and lower surfaces of the workpiece to symmetrically cool the workpiece.

Abstract: A system for incremently and continuously feeding tubes between dies during a prescribed angle of rotation of a crank assembly in a cold pilger mill. As a main motor drives the crank assembly, a servo-motor, receiving a signal from a digital control unit, which receives a signal from a pulsating encoder associated with the main drive, operates to incremently advance a carriage and shell a controlled predetermined distance between the dies. A reversal of the servo-motor returns the carriage to the initial position in preparation to advance another shell.

Abstract: The present disclosure relates, in combination with a draw block, to a continuous type takeup block and spooler and a stripper for employment in the manufacture of metal wire to form selectively spooled bundles or coiled bundles of wire. The combination consists of a gear-driven unit for internally driving a draw block having an upper supporting surface for alternately supporting for operation therewith a stripper or second block in the form of a continuous accumulating block from which wire is passed to a spooler; the latter being employed when spooled bundles are to be formed and the former, when spool-less bundles are desired.

Abstract: An apparatus located alongside a multiplaten vulcanizing press in combination with a clamping device for stretching or tensioning elastomeric belt prior to closing the press, and maintaining the belt in alignment with the press platens while the press is closing to assure a uniform tensioning of the belt.

Abstract: An arrangement for controlling the temperature of an arbor-sleeve type roll employed in a rolling process such as in a briquetting machine by transporting temperature control medium to the extremities of the working surface of a removable sleeve by providing in the arbor a system of passageways extending radially and terminating at a point beneath the outer surface of the arbor and by providing in the sleeve a system of interconnecting axially extending passageways. Both of these systems are joined by manifold ring assemblies mounted externally of the roll and which include an expandable bellows which compensate for thermal variation of the roll during the briquetting process. Two other rings, also mounted externally, are connected to the opposite sides of the arbor and sleeve, thereby preventing relative movement between the arbor and sleeve and still permitting the quick removal and replacement of the sleeve.

Abstract: The disclosure relates to a workpiece feed apparatus for cold pilger rolling mills having at least one feed spindle for at least one feed carriage, and having a feed transmission which is connected to the main drive and comprises two branches or lines of drive, of which the first line of drive is connected with a gear wheel secured on the feed spindle for producing a continuous rotational movement of the feed spindle, and the second line of drive is connected by way of an intermittently moved lever with the feed spindle for the purpose of producing an intermittent axial movement of the feed spindle.

Abstract: A strip contacting device used between stands of a rolling mill for simultaneously performing combined modes of operation, such as a shapemeter/looper or a shapemeter/tensiometer. It consists of a frame with a pivotal arm connected to a piston cylinder assembly, whereby a desired mode can be carried out by using a shapemeter roller and allowing the arm to either float or assume a fixed position relative to the passline of the mill.

Abstract: The disclosure of this invention pertains to a strip guiding mechanism for use with a rotating mandrel around which strip is wound into a coil. The guiding mechanism consists of two carriages movable in opposite radial directions towards and away from the mandrel. The carriages are mounted on a common frame that is movable in an axial direction of the mandrel to a position in front thereof after the coil has been started and then the frame is rotated to remove the carriage from the front of the mandrel to allow on completion the removal of the coil from the mandrel.

Abstract: The disclosure concerns a roll changing device for roll stands of a rolling mill or the like having a pair of working rolls and backing rolls assigned to each working roll in which the roll pairs, including their component bearing parts, can be moved as separate units into and out of the windows of the housings of the mill. A piston cylinder assembly provided for this purpose is arranged in front of the understructure for the support member of the lower backing roll.

Abstract: Transfer apparatus for a workpiece such as a metal slab, bloom or coil of metal strip comprises a carriage supported on a substantially horizontal beam. The beam is displaceable in the direction of its length and the ends of a flexible cable are connected to opposite ends of the carriage with a reach of the cable extending substantially parallel to the length of the beam. An intermediate point of the cable is firmly anchored so that displacement of the beam causes the carriage to be displaced along the beam as well as its movement with the beam. The beam can also be raised and lowered.

Abstract: The disclosure of this application relates to a looper device employed to impose a constant tension on a strip as it passes between the stands of a tandem rolling mill. The looper is operated by an hydraulic actuator which is controlled by a computer controlled hydraulic servosystem. The computer is fed a signal of the position of the looper and calculates the required pressure difference across the actuator for a desired tension.

Abstract: The present disclosure relates to a method and a machine for forming stranded wire into a wire cord and comprises the steps and elements of mounting several spools of individual wire strands on a common arbor in a manner that the strands may be unwound in the same direction and fed to a gathering sheave, rotating means for supporting two spaced-apart flyer sheaves arranged radially upward of said gathering sheave, said flyer sheaves being arranged so that the several strands are fed radially outward from said gathering sheave and, hence, from one flyer sheave to the other and, thence, to a discharge station arranged coaxially with said gathering sheave and on the same side of a wire coiling means adapted to pull the wire through the machine, the construction and arrangement of elements being such that the individual strands of wire are caused to be formed into a wire cord in which the number of twists per unit length is a function of the speed of travel of the wire and the revolutions per minute of the rotati

Abstract: A rolling mill stand for hot or cold rolling rod and flats has a C-shaped housing and a bolt connecting the protruding ends of the housing. The work rolls are mounted in cantilever fashion and are carried in chocks which are restrained by the housing. The chocks are pivoted to the housing about pivot pins, the axes of which are parallel to the axes of the work rolls and are displaced from the plane through the roll axes. Pivoting of the chocks about the pivot pins in order to vary the separation of the work rolls does not affect the shape of the roll gap.

Abstract: An apparatus for distributing a controlled flow of water onto passing hot strips in proportion to the varying width of strips as they issue from a hot strip rolling mill.
