Flat pallet decoiler for thin strip coils
Horizontal Decoiler Machine for Thin, Narrow Metal Strip
HENLI horizontal decoilers, also called flat disc uncoilers or pallet decoilers, place the coil flat on a rotating pallet and supply narrow metal strip to feeders, levelers and stamping presses. Compare YTE induction, YTF inverter and YTG auto-tracking configurations from the actual coil and line data.
Overview
Horizontal Pallet Decoiler Machine Overview
A horizontal decoiler supports the coil on a flat rotating disc instead of an expansion mandrel. This layout is intended for selected thin, narrow and surface-sensitive metal strips used in terminals, contacts, progressive stamping and compact press lines.
What makes the flat-pallet structure different?
The coil lies flat on the disc, so a fixed coil inner diameter is not required for mounting. Model selection should instead use coil outer diameter, weight, stack height, strip width, thickness, material behavior and the complete feeding-line layout.
This configuration can simplify coil preparation and support multiple coils on one pallet when the verified coil data and safe stack height allow it. It should not be treated as a universal replacement for a vertical mandrel decoiler used with wide, thick or heavy coils.
Selection boundary: use the broader Decoiler Machine range when the project needs expansion-mandrel support, wider strip or heavy-duty coil handling.
Selection logic
Choose the Horizontal Decoiler from Coil and Line Data
Start with the material and production conditions. A model name alone cannot prove that the pallet size, carrying capacity or control response will match the line.
Material
Confirm copper, brass, aluminum, stainless steel or steel grade, temper and surface sensitivity.
Strip size
Provide the maximum width and thickness, including the complete product mix.
Coil data
Provide maximum coil O.D., actual coil weight and the planned stack height.
Line speed
Provide required line speed, press SPM and feed pitch, not press tonnage alone.
Material path
Confirm sensor position, guide path, loop window and downstream feeder or leveler.
Workshop layout
Confirm floor space, feeding direction, power supply and safe coil-loading access.
Surface and stability check: if the strip is easy to scratch, stretch or twist, supply samples or project photos so the pallet edge, guides, loop geometry and commissioning method can be reviewed.
Control types
Compare YTE, YTF and YTG Horizontal Decoilers
The mechanical flat-pallet concept is similar across the series. The main difference is how the drive responds to loop demand and how speed is adjusted for the downstream line.
Standard Induction Type
Motor-driven pallet rotation with loop-demand start and stop control for standard light-duty production.
- Speed0-20 m/min reference
- ControlInduction start/stop
- UseStable standard production
Electronic Inverter Type
Adds VFD speed adjustment for production lines that need a set speed reference and smoother adjustment.
- Speed0-30 m/min reference
- ControlInverter and speed knob
- UseHigher-speed or sensitive lines
Auto-Tracking Electronic Type
Uses responsive loop-demand tracking for thin strip and changing line conditions. Final sensor and control logic require configuration confirmation.
- Speed0-30 m/min reference
- ControlAuto-tracking configuration
- UseResponsive loop-control projects
Important: these systems help manage the material loop; they do not by themselves guarantee constant tension, zero scratches or perfect synchronization. Commissioning must use the actual strip, feeder and press conditions.

Special configurations
Mini and Double-Layer Horizontal Decoilers
These project configurations are shown separately from the standard YTE/YTF/YTG tables. Their control method and carrying capacity must be confirmed from the actual equipment quotation and project data.
Compact Mini Pallet Uncoiler
A compact configuration for selected ultra-thin strip, small batches, test lines and workshops with limited floor space.
- Confirm pallet diameter and carrying weight from the project.
- Confirm material, coil O.D., stack height and downstream speed.
- Do not assume the standard model table applies to the Mini frame.
Double-Layer Horizontal Decoiler
Two stacked pallet positions can support prepared coil changeover or another verified project arrangement while reducing floor-space demand.
- YTE or YTF control must be verified from the actual electrical configuration.
- Confirm carrying capacity per layer; no unverified double-layer load is published.
- Confirm whether the project uses alternating preparation or simultaneous material paths.
Line integration
How a Horizontal Decoiler Works in the Feeding Line
The decoiler should be commissioned as part of the complete line. Pallet rotation, guide position, buffer loop and downstream demand must work together under the actual strip conditions.
Load the coil flat.
Confirm pallet size, coil weight and safe stack height before operation.
Guide the strip.
Set the release direction, guide path and sensor position for the material.
Build a usable loop.
The induction or tracking system responds to loop demand; it does not directly prove strip tension.
Commission with the line.
Test at low speed, then verify the required line speed, press SPM and feed pitch.
Comparison
Horizontal Decoiler vs Vertical Mandrel Decoiler
Both machines release coil material, but they fit different coil sizes, loading methods and production goals.
| Selection point | Horizontal pallet decoiler | Vertical mandrel decoiler |
|---|---|---|
| Typical material | Thin, narrow strip within the verified model range. | Wider, thicker or heavier coils depending on model. |
| Coil mounting | Coil rests flat; fixed coil I.D. is not required for mounting. | Coil fits an expansion mandrel with a suitable I.D. range. |
| Primary selection data | Coil O.D., weight, stack height, strip data and loop layout. | Coil I.D./O.D., width, weight, expansion and loading method. |
| Changeover | Multiple coils may be prepared when the validated stack allows it. | Commonly loads one coil per mandrel; options depend on machine structure. |
| Typical applications | Terminals, contacts, small hardware and thin-strip stamping. | Automotive panels, wider strip, heavy-duty feeding and cut-to-length lines. |

Applications
Where Horizontal Pallet Decoilers Are Commonly Used
Horizontal pallet decoilers supply thin, narrow strip to terminal stamping, precision small-part production and compact press lines. Select the arrangement from the material, coil dimensions, surface requirements and downstream feeding conditions.
Electrical Terminal Stamping
Narrow copper or brass strip feeding for connector terminals, contacts and conductive pieces.
Precision Small Parts
Selected thin stainless, aluminum and copper-alloy strips for compact progressive stamping cells.
Small Metal Components
Buttons, clips, shims and similar parts when strip width, weight and line speed fit the machine range.
Feeder and Leveler Integration
Works before a feeder, leveler or stamping press after the complete material path is commissioned.
Quotation checklist
Send Your Coil Data for Horizontal Decoiler Selection
For an accurate model and price, provide the actual coil, strip and production-line conditions. This lets HENLI confirm whether YTE, YTF, YTG, Mini, Double-Layer or another decoiler type is suitable.
Do not select only from the pallet diameter
The same pallet diameter can be paired with different frame, drive and control configurations. Mini and Double-Layer carrying capacities are not published until the exact machine record is verified.
