Building Products ยท Press-Side Lubrication
This pneumatic roller oiler applies a controlled film to both sides of metal strip immediately before stamping. Signal-controlled and timed operating modes let the oil supply follow the press cycle or run at a set interval, helping building-component manufacturers replace manual application with a cleaner, more repeatable process.
The system was prepared for a building-products manufacturer whose production covers metal roofing, facade and fencing systems, cable trays, mounting profiles and related hardware. Many of these product families also require stamped brackets, connectors, joining plates, clips or perforated accessories. For those press operations, stable lubrication helps the strip pass through piercing, blanking and forming steps with less dependence on manual oiling.
The supplied configuration combines enclosed roller heads, adjustable mounting hardware, a pneumatic oil-supply module, selectable control logic, low-oil indication and return plumbing. Installed close to the press, it creates a short and controlled path from lubrication to the die.
Where the Strip Oiler Fits in Production
In a building-products factory, long roofing and facade panels are commonly roll formed, while smaller accessories and connection parts are produced on punching or stamping presses. The strip oiler serves these press lines by placing lubricant on the material just before the working area.
Typical process route
Prepared strip โ roller oiler โ press or punch โ inspection and the next operation. The short distance to the die helps preserve an even oil film.
Suitable component families
The arrangement can support brackets, connectors, clips, perforated accessories, mounting parts and other strip-fed components used in building systems.
Why coat both sides
Upper and lower rollers apply lubricant across both strip faces, supporting die contact while avoiding the uneven coverage common with brushes or hand application.
Why install near the press
Press-entry placement reduces exposed travel after coating and makes it easier to inspect roller contact, oil coverage and the strip path during setup.
System Configuration Supplied for the Press Line
The delivered system includes multiple enclosed roller-head assemblies, adjustable clamps, hoses and fittings, plus a pneumatic supply and control module. The modular arrangement allows the roller head to be positioned around the existing strip path while the supply unit remains accessible for filling, adjustment and maintenance.



Oil is delivered to the roller head through the pneumatic module. The enclosed housing distributes the fluid to the working rollers, while the return connection collects excess oil for controlled drainage or filtered recirculation according to the plantโs maintenance policy.
How Signal, Timed and Manual Modes Work
The control panel includes a timer, a signal/time selector, a manual oil-feed button and a low-oil alarm. Operators can choose the control method that best matches the press sequence and production rhythm.
Signal-controlled supply
The press, PLC or cam sends a command to replenish oil in step with production. This mode is useful when lubrication should follow machine operation and stop when the press stops.
Time-based supply
The pump replenishes the rollers at a set interval. It is practical when a direct press signal is unavailable or when the line needs an independent and adjustable oiling cycle.

Use the manual oil-feed button to prime the rollers after filling, cleaning or a long shutdown. During production, the low-oil alarm reminds the operator to replenish the tank before the working rollers run dry. A quick visual check of both strip faces at the start of each job confirms that the film is continuous and evenly distributed.
Press-Side Installation and Setup
The installed arrangement places the roller head directly in front of the press tooling. Flat strip passes between the upper and lower rollers, receives a controlled oil film and then enters the die. Correct pass-line alignment keeps the strip stable and prevents one edge from carrying more roller pressure than the other.

| Interface | Why it controls the result | What to verify on site |
|---|---|---|
| Pass line and centreline | A tilted or offset roller head can pull the strip sideways or load one edge | Mounting height, parallelism, guide path and clearance through the full die cycle |
| Upper/lower roller contact | Contact should transfer a stable film without bowing, marking or resisting feed | Material thickness, surface sensitivity, roller condition and contact setting |
| Pneumatic and oil supply | Stable air pressure and unrestricted flow keep the roller surface replenished | Clean dry air, regulator setting, compatible fluid, hose routing, leakage and priming |
| Press signal or timer | Correct timing prevents unnecessary oiling during idle periods and keeps up during production | Input logic, cycle relationship, pause/restart behaviour and manual control |
| Oil return and filtration | A clear return path limits pooling around the roller head | Drain slope, return capacity, filter condition and the plantโs reuse policy |
| Guarding and access | The oiler is positioned close to moving strip and press tooling | Safe threading, cleaning access, interlocks and lockout procedures |

Commissioning the Oiler for a New Job
Record strip width, thickness, surface condition and the approved oil. Include any later cleaning, welding, painting, bonding or assembly requirements.
Set the roller head to the feed centreline and confirm easy threading, guide clearance, tooling travel, access and guarding before adding oil.
Check the air supply, regulator, electrical connection, signal input or timer setting, alarm circuit, hose routing and return connection.
Use manual oil feed to wet the roller surfaces. Confirm that the full working width receives fluid and that all connections remain dry.
Run normal production, slow cycles, pauses and restarts. Make sure oil delivery starts and stops with the selected control method.
Inspect both strip faces, feed stability, the die area and stamped parts. Reduce excess oil while maintaining a continuous film.
Production Advantages for Building-Component Stamping
More repeatable than hand oiling
Rollers distribute lubricant continuously across the strip instead of relying on an operator to brush or spray the material at intervals.
Controlled use of lubricant
Signal or timed replenishment supplies the working rollers when needed, making it easier to reduce dripping, splash and unnecessary consumption.
Faster job changeovers
Adjustable roller contact and recorded control settings help the line move between approved strip widths, thicknesses and die operations.
Easier daily maintenance
The low-oil alarm, enclosed head and return path give operators clear points for filling, inspection, cleaning and oil management.
Choose Gravity or Pneumatic Oil Supply
Both systems can feed a roller head, but the right choice depends on production speed, oil demand, control requirements and the available utilities.
Choose a compact gravity system when
- The approved oil flows reliably without a pump.
- Production demand is stable and relatively simple.
- The plant wants a low-complexity installation with visual level checks.
Choose active pneumatic supply when
- Oil replenishment should follow a press signal or timer.
- The roller head needs more dependable delivery during changing production speeds.
- Manual priming, a low-level alarm and a planned return path are useful operating features.
Compare the options using the lubricant viscosity, strip width, line speed, duty cycle, roller width and maintenance method. HENLI can configure gravity, electric or pneumatic supply around the same basic requirement: applying an even film to the strip before stamping. See the automatic oil feeder selection guide for a broader comparison.
Frequently Asked Questions
Does the roller oiler coat both sides of the strip?
Yes. The strip passes between upper and lower contact rollers so lubricant can be transferred to both faces. Roller contact and oil delivery are adjusted for the material thickness, width and required film.
When should signal mode be used instead of timed mode?
Use signal mode when oil delivery should follow the press or PLC sequence. Use timed mode when the pump should replenish the rollers at an independent interval. Test pauses and restarts before releasing the line for production.
Can the oiler be retrofitted to an existing press?
In many cases, yes. The main checks are available space, pass-line height, strip centreline, mounting points, threading access, guarding, air supply, electrical control and the distance from the roller head to the die.
What information is needed for a quotation?
Provide the strip material, width and thickness, lubricant, line speed, die operation, required working width, preferred control mode, available air and power, plus photos or a dimensioned drawing of the press-entry area.
