roller-feeder application page for backing plates
A roller feeder is credible for backing plates when fixed-pitch mechanics, release geometry, roll traction, backlash, lubrication and pitch verification are tied to the actual strip and die.
Application-Specific Process Route
The route below covers fixed-pitch setup, traction, mechanical release and maintenance checks for backing-plate strip.
Inputs to Freeze Before Selection
- Backing-plate strip material, strength, thickness and width
- Fixed pitch, roll diameter/ratio and press mechanical interface
- Roll surface/pressure, guide positions and lubrication constraints
- Release stroke/timing, pilot holes and die drag
- Backlash/wear checkpoints and preventive-maintenance frequency
- Plate pitch, hole position, burr, flatness and surface checks

Engineering Decision and Verification Table
| Decision gate | How to verify | Required record |
|---|---|---|
| Travel ratio | Calculate and measure one press-cycle feed | Setup record |
| Traction | Inspect slip and roll marks on production strip | Marked sample |
| Release | Observe pilot correction in single cycle | Timing/witness evidence |
| Maintenance trend | Measure backlash and plate features at interval | Trend report |
Step-by-Step Verification
Work through the four gates below with the production drawing, material and real machine interface. Each gate produces a record that can be reviewed before production.
Travel ratio
Calculate and measure one press-cycle feed Record: Setup record
Traction
Inspect slip and roll marks on production strip Record: Marked sample
Release
Observe pilot correction in single cycle Record: Timing/witness evidence
Maintenance trend
Measure backlash and plate features at interval Record: Trend report
Failure Modes and Stop Conditions
- Pressure compensation: Do not over-compress strip to hide wear or die drag
- Release wear: Stop on witness marks or pilot loading
- Pitch drift: Contain production from the last verified measurement
Acceptance Record
Freeze the released drawing and material revision, machine configuration, interface list, recipe, sample plan and measuring method. Record exceptions and the safe restart route, and identify the tested configuration in every reported result.
Comparing Feeder Types
The HENLI feeder architecture comparison frames the choice between air, roller and NC servo feeding. For a safety-related component, no feeder type is a universal winner; the choice is confirmed on the actual strip and die.

Request an Engineering Review
Send the drawing, material, line sequence, target cycle, interfaces and acceptance method for roller feeding for automotive brake backing plates. HENLI can confirm what is standard and what needs to be engineered for your line. As a roller feeder manufacturer, HENLI publishes RFS model limits for strip width, feed pitch and thickness (up to 3.5 mm on suitable models); check your backing-plate strip against them first.
