Use this worksheet to prepare a quote-ready decoiler specification. It collects the information needed to choose a machine family and define the engineering checks; it does not generate an automatic model or replace the current product table and project proposal.
Worksheet A: Material and Strip
| Field | Buyer input | Why required |
|---|---|---|
| Material grade/condition | ________ | Defines strength, springback and handling behavior |
| Yield/tensile data | ________ | Supports selection beyond material name |
| Thickness min/max | ________ | Must be checked with width and strength |
| Width min/max | ________ | Controls working face, load position and guides |
| Surface/film/oil | ________ | Defines allowed contact and cleanliness |
| Coil set/edge condition | ________ | Affects threading, restraint and downstream work |
Worksheet B: Coil Package
| Field | Minimum | Maximum | Notes |
|---|---|---|---|
| Coil weight | ____ | ____ | Include heaviest actual package |
| Coil inner diameter | ____ | ____ | State core tolerance/material |
| Coil outer diameter | ____ | ____ | Controls inertia and clearance |
| Coil width | ____ | ____ | State telescoping/offset condition |
| Packaging/eye orientation | ________ | Include pallet, bands and protection | |
Worksheet C: Downstream Process and Duty
| Field | Buyer input |
|---|---|
| Downstream machine/model | ________ |
| Process | Stamping / roll forming / CTL / slitting / treatment / other: ____ |
| Line speed or press SPM | ________ |
| Start-stop/acceleration profile | ________ |
| Downstream traction source | ________ |
| Changeovers and duty hours | ________ |
| Required production jobs | ________ |
Worksheet D: Payoff and Control Architecture
- Powered or passive
State whether downstream equipment can pull the coil and how inertia will be controlled. - Mandrel or plate support
Confirm coil ID/core and loading geometry. - Loop control
State free-loop space, sensor type/zones and upper/lower behavior. - Process tension
If a defined tension is required, state range, measurement and control architecture. - Line signals
List run permission, demand, stop, alarm, E-stop and responsibility boundaries. - End-of-coil behavior
Define tail containment, stop sequence and scrap/strip handoff.
Worksheet E: Loading, Site and Utilities
| Field | Buyer input |
|---|---|
| Loading method | Crane / forklift / coil car / other: ____ |
| Passline and feed direction | ________ |
| Available footprint/loop space | ________ |
| Floor/foundation constraints | ________ |
| Power/air/hydraulic availability | ________ |
| Destination and standards | ________ |
| Operator/service access | ________ |
Which Options Need Separate Confirmation?
Mark each as required, optional or not required: hydraulic expansion, coil car, hold-down arm, side keepers, outboard support, pneumatic/other brake, VFD, contact/photoelectric/ultrasonic sensor, guards, threading aids and special electrical standard. Do not select an option from a universal weight or thickness threshold.
What Should the Supplier Return?
- Rated family/model.With the applicable material, coil and duty conditions.
- Configuration drawing.Support, expansion, drive, brake, options, passline and footprint.
- Interface definition.Loading, downstream traction, signals, utilities and responsibilities.
- Supply-scope matrix.Included, optional, excluded and buyer-supplied items.
- Validation plan.FAT/SAT, test material, criteria, records and punch-list closure.
Which Attachments Make the RFQ More Reliable?
Attach the material certificate/data sheet, coil and core photos, largest/smallest coil drawings, current line layout, downstream machine manual/interface, desired material path, utilities, site photos, product acceptance criteria and any retrofit measurements.
Frequently Asked Questions
Can HENLI select a model if some fields are unknown?
Unknown fields can be marked TBC, but the proposal should state assumptions and the decision cannot close until critical inputs are verified.
Is coil weight the most important field?
It is important but not sufficient. Width, ID/OD, material, load position, duty, support and loading method must be reviewed together.
Can this worksheet approve a used decoiler?
No. A used machine also needs identity, condition, documentation and functional inspection against the intended job.
