Full Product Description

Model:  4RS-13-280

Capacities based on steel up to 40,000 PSI yield strength:

* Circular bending to diameters 5 times upper roll dia and
larger .............. 13' X 5/16"

* Circular bending to diameters 1-1/2 times upper roll
diameter and larger . 13' X 1/4"

* Prebending to diameters 5 times upper roll diameter and
larger .............. 13' X 1/4"

* Prebending to diameters 1-1/2 times upper roll diameter
and larger .......... 13' X 5/32"

(With prebending, resulting flat ends are 1-1/2 to 2 times
plate thickness or less.  Proportional capacities in other
material, widths and thicknesses.  Cone Bending capacities
50% of each length and thickness capacities.)          

SPECIFICATIONS:
Overall working length:.......................... 161.4"
Diameters of the upepr & lower central rolls .... 11.03"
Diameter of each side roll ...................... 8.67"
Rolling speeds, dual ....................  5 AND 16-1/2 FPM
Motor HP ........................................ 21-1/2
Dimensions ..............................  268" x 67" x 73"H
Weight .......................................... 28,600 lbs


FEATURES:
* Four roll design and construction.  Compact design for
minimal floor space.  Welded, all-steel, heavily
proportioned, thermally stress-relieved frame and drop-end. 
Roll shafts journalled in self-lubricating bronze and
spherical roller bearings.  Induction-hardened SAE 1050
steel bars, hardened to 55-58 Rockwell C are used for the
rolls.  Rolls are precisely machined wtih crowning to
compensate for deflection under load.

* Fully-Hydraulic:
Three-roll drive:  The upper central and each of the two
side bending rolls are driven, each by a hydraulic motor
through a planetary gearbox from a central hydraulic power
system.

* The lower central roll and the two side bending rolls are
hydraulically and individually adjustable and tiltable. 
Each side roll is adjustable hydraulic and independently to
provide double pre-bending; therefore each end of the
workpiece can be prebent and then rolled with only one
insertion of the workpiece into the machine. 

* Linear movement (slide) of the side rolls for more
powerful and efficient rolling of medium to heavy
capacities.

* Dual rolling speeds.

* Balancing system for roll parallelity.

* Robust drop end, hydraulically operated.

* Controls for all functions and electronic digital readouts
in a rolling console.

* Cone bending attachment is standard equipment; and the
side rolls can be tilted for more effective cone rolling,
after which they can be easily paralleled for normal
bending.

* All the advantages of asymmetrical, pyramid and double
pinch bending.

* 3-Electronics digital readouts (LED) for the positions of
the side rolls and the lower roll, each with programmable
roll position pre-set and memory.

* Components are from world-renowned sources. Hydraulics by
Rexroth, Bosch, Duplomatic or Parker.  Electrics by Siemens,
NAIS, or Telemecanique.  Bearings by FAG and SKF.

* Pre-arranged for easy retro-fit of overhead and side
support devices if required after machine has been put into
operation.

* Built according to stringent European standards for
design, production and quality and bearing the CE Mark of
certification.


OPTIONAL EQUIPMENT:
* Hydraulic side support device for front or back of
machine, or both.
* Hydraulic overhead support device, adjustable to 98"
(other sizes can be ordered)
* Siemens "Teach-in" Numeric Control with integrated PLC,
color screen, and integrated floppy discette. This control
is offered as an alternative to a full CNC because it is so
much more simple to operate and costs much less, but still
provides excellent numeric control.
* CNC control
* Infeed tables
* Hydraulic finished parts ejector
* Linear electronic digital readout (LED) for the upper roll
* Ground and polished rolls
* Modifications to suit customer's requirements.
