Himalaya’s Linear Guided Plate Bending Machines deliver at par performance and flexibility at much lower costs compared to the more expensive 4-roll plate bending machines. They are also extremely durable and accurate compared to swing guide machines and are therefore ideal for medium-to-heavy duty rolling.
The bottom rolls in our linear guideway plate rolling machines, are positively guided in the machine frames. The axis of bottom rolls is closer to the top roll. The close spacing between top roll and bottom rolls improves circularity of the rolled shell. Hence accuracy of resultant job is better than swing guide or variable geometry machines.
Our design ensures that the bending forces are directly transferred from cylinders to rolls, as no linkages are involved in our design. Hence, there is no wear and tear of the guideways and roll parallelism is maintained. Compared to this, the swing-guide design transfers the load to the links on which the rolls are hinged which are weakest part of the joint and can result into increased chances of fatigue and failure.
The front and back frames of our machines are cut and machined together as a single piece. This leads to an extremely accurate alignment of the guideways in which the bottom rolls move. This results in excellent precision of roll movement and superlative bending quality.
Himalaya’s linear guided machines deliver a multi-fold advantage to your fabrication infrastructure - a remarkably efficient and lasting performance, an unbeatable edge bending precision, reduced capital expenditure, lower ongoing operational and maintenance costs.
The HIMALAYA Advantage
-
What is done to compensate for deflection of rolls during pre-bending and rolling?All rolls are crowned (cambering) for compensating deflection.
-
What is the arrangement provided for balancing of top roll when swing arm is opened?Top roll is counter balanced automatically once the drop end is opened without any jacks or manual arrangement.
-
Is there any method to know the position of bottom rolls?DRO (Digital Readout) is housed on the operating console which gives the position of the bottom rolls with respect to the top roll.
-
What is the capacity for cone bending?Cones can be bent up to the edge-bending capacity of the machine. The bottom rolls can be inclined for the required cone angle.
-
What is the level of protection for electrical components?Some of the electrical bough outs are IP 55 like motors, switchgears etc. The electrical cabinet will be manufactured as per our standard practices and will meet IP 55 protection.
-
Is the main drive reversible?Forward and reverse to the main drive is provided. The bottom rolls can be moved up and down individually.
-
What is the type of oil required?Hydraulic oil – Enklo 68 Planetary Gear box – EP 90
-
Where are the main machine controls?Operating console houses push buttons for all the operations of the machine. The console is movable so that the operator can keep it at any desired location.
-
Can we bend hot plates on the machine to get higher thickness capacity?Although the standard machine is not meant for hot rolling, occasional hot rolling can be done (a few jobs per month) provided that suitable precautions are taken.
-
Some plates have high yield point (YP). The rolling capacities are rated for 26Kg/mm2. How to find the equivalent thickness?Divide the Actual YP by 26. Find square root of this number. Multiply this value by actual plate thickness to get effective thickness.
Enjoy the peace of mind that you are in good hands.

Build Quality & Benefits
Sturdy Steel Structure
Himalaya 3 roll plate bending/rolling machines have a robust steel structure made from heavy metal plates. The frames are connected to each other by a strong box design chassis. The frames have interlocks & strengthening ribs. The roll guideways are machined together utilizing a fixed single reference point which allows for parallelism of all axes and precise surfaces, as well as longevity and precision of the critical characteristics of the machine.
Rolls
The rolls are the most important elements of our machines. Himalaya designs the rolls with optimal diameter and uses forged carbon steel rolls that are machined by high precision CNC lathes. Our rolls have a special spline-based design that is extremely efficient in connecting the rolls with the planetary gear system. This diminishes points of roll failure compared to welded connections provided by other manufacturers.
Crowning
Our rolls are crowned to compensate for roll deflection during the bending process. Custom crown-machined rolls for different materials or thickness can be selected when ordering.
Hydraulic Gear System
Additional energy saving is ensured in our three roll machines by a hydraulic system which can work at less than full capacity when jobs less than maximum thickness are rolled. Twin speed operation also reduces the energy consumption up to 50% when slower operating speed is selected.
​
Himalaya Planetary driving system ™ used in our machines is efficient and eliminates energy wastage associated with heavy-transmission systems and yet achieves the goal of speed reduction by increasing the stages in gears and pinions.
Operational Benefits
Pre-Pinching (Edge-Bending)
1
2
3
Pre-Pinching (which is also known as Edge bending) can be done before or after shell rolling depending on operator skill and choice. Thin plates can be rolled and edge-bent in a single pass.
Easy Cone Bending
The cone bending process with the K series is simple. The bottom rolls need to be inclined to achieve cone bending geometry. This is controlled and monitored by electronic microprocessor (on some models).
​
Our control system also ensures easy and accurate return to parallel setting after cone bending resulting into precision on repetitive jobs.
