RFQ data for fixed-pitch press feeding
A useful roller feeder RFQ checklist should do more than ask for feeder width and material thickness. In high-speed fixed-pitch stamping, the quote depends on press motion, die release timing, strip behavior, coil handling, line height and the way the feeder is mechanically synchronized with the press.
Executive Summary:
- The RFQ should start with the stamping press, not only the feeder model.
- Material width, thickness, coil data and surface condition decide roller selection and upstream coil handling.
- Feed pitch, die pilot release and stroke angle decide whether a mechanical roller feeder fits the job.
- A complete quote needs line-layout data so the feeder, decoiler and straightener are not selected in isolation.

ToggleWhat press data should be included first?
A roller feeder is driven and released around the stamping press cycle, so the first RFQ block should describe the press. Useful inputs include press type, nominal speed range, stroke angle, output shaft position, available drive connection, die shut height, line height and whether there is room on the slide for the feeder's release striker.
Press motion
Press speed, stroke angle, output shaft and feeder release timing.
Die condition
Pilot pins, strip lift, guide height, feed window and release requirement.
Line connection
Mechanical drive space, electrical signal and available installation layout.
Which material and coil data matter most?
Material data decides whether the feeder can grip the strip without marking it, whether upstream straightening is required, and how much coil handling capacity is needed. The RFQ should list material grade, strip width, thickness range, surface condition, coil inner diameter, coil outer diameter, coil weight and whether the strip is oiled, plated, polished or soft.
How should feed pitch and die timing be described?
Fixed-pitch roller feeding is strongest when the stroke is repetitive and the die can correct final location through pilot pins. For that reason, the RFQ should state feed pitch, pitch tolerance expectation, target strokes per minute, strip layout, pilot-pin timing, release angle and whether the material is likely to spring, buckle or move backward after feeding. If the die uses pilot pins, say so clearly, because the rollers must release the strip for the pilot pins on every stroke.
A practical rule:
If feed length changes often, an NC Servo Feeder may be easier to quote. If the job is fixed pitch, high volume and mechanically synchronized, a high-speed roller feeder can be a stronger fit.
What line-layout information prevents quote mistakes?
A feeder quote can become misleading when the upstream line is unknown. Buyers should confirm whether the project needs a simple decoiler, a motorized decoiler, a straightener, a compact 3 in 1 Decoiler Straightener Feeder, a lubrication unit, scrap handling or special mounting brackets. Workshop constraints also matter: floor space, coil loading direction, press entrance height and operator access.
Copy-ready roller feeder RFQ checklist
The table below can be copied into an inquiry email before requesting a quote. If some values are not confirmed yet, mark them as pending instead of guessing. Send the completed table with your inquiry so we can check the suitable RFS model, mechanical linkage and release timing for your high speed roller feeder quote.
| RFQ block | Data to prepare | Why it matters |
|---|---|---|
| Press | Press type, SPM, stroke angle, output shaft, line height | Defines feeder drive, timing and mounting method |
| Material | Width, thickness, grade, surface, coil ID/OD, coil weight | Defines roll grip, surface risk and upstream coil handling |
| Die | Feed pitch, strip layout, pilot release, die entry space | Prevents timing mismatch and pitch-control problems |
| Line | Decoiler, straightener, oiler, scrap handling, workshop layout | Connects the feeder quote with the complete production path |
When should the RFQ ask for a full feeding line instead?
If the material has coil set, the coil is heavy, the surface is sensitive, or the press entrance has limited space, quoting the feeder alone may not be enough. In those cases, the RFQ should ask for a configured press feeding system that includes uncoiling, straightening, feeding and optional stock oiling. This makes the quote easier to compare and reduces the risk of missing a required machine module.

FAQ about roller feeder RFQ checklist
What information is needed for a roller feeder quote?
Prepare press speed, stroke angle, output shaft details, material width and thickness, coil size, feed pitch, die release timing, line height and workshop layout.
Why does the RFQ need die timing data?
Die timing data shows when the strip must be released for pilot correction and when the feeder can safely grip and feed again during the press cycle.
When is a roller feeder better than an NC servo feeder?
A roller feeder is usually stronger for stable fixed-pitch, high-volume stamping where press synchronization is valuable. An NC servo feeder is usually better when feed length changes often.
