Motorized single-mandrel decoiler for metal-strip payoff
Powered coil payoff ahead of straightening and strip feeding
A motorized mandrel decoiler supports the metal coil at its bore and rotates it to release strip into a processing line. The stand carries the coil while the drive follows the required payoff. Its loading and support arrangement, strip loop and connection to the downstream straightener or feeder form the ordering scope.
Motorized single-mandrel decoilers for metal-strip payoff, with coil support, driven spindle and downstream loop/control interfaces. The automated stamping line includes the press, straightener, feeder and production controls as a wider system. Hot forging lines (484), compact stamping modules (3220), double-mandrel changeover reels, pallet decoilers and complete decoiler-straightener-feeder packages are separate configurations.

Specify the coil envelope and mandrel arrangement together
Machine Concepts describes a decoiler/uncoiler as a machine that grips a coil with a mandrel and unwinds material into downstream equipment. It offers single- and dual-mandrel configurations and separate duty series. Coil mass and width therefore need to be checked against the selected configuration rather than a brand-wide maximum. [1]
Qiaosen’s MT-200 product page describes a motor and reducer driving the unit through a belt. It also identifies the welded frame, shaft support and electrical control box. These are properties of that listed machine, not evidence that every decoiler has hydraulic expansion or an identical transmission. [2]
Include the coil bore, outside diameter, strip width, coil mass, material and loading direction in the enquiry. Identify the mandrel contact and retaining arrangements on the drawing, including any adapters, support arm or coil car included in the offer. [1][3]
02
Distinguish powered payoff into a loop from a pull-off reel
COE distinguishes motorized reels, which advance strip into a loop, from pull-off reels used with a powered straightener that draws the material. In the pull-off arrangement, its description assigns drag-brake control to maintaining the strip between reel and straightener. Select the control architecture before specifying the reel drive and line interface. [3]
Qiaosen describes an induction frame controlling start/stop on its listed powered uncoiler. COE separately lists ultrasonic variable-speed loop control and hold-down equipment among options. These are different named implementations; specify which feedback and threading functions are supplied for the proposed line. [2][3]
Machine Concepts places the decoiler ahead of straightening and other coil processing equipment. Coordinate the available strip loop, threading route and downstream stop/start demand with those machines. The decoiler speed alone does not define the stamping line’s output or feed accuracy. [1]

Buyer questions
Is a motorized decoiler the same arrangement as a pull-off reel?
COE distinguishes a powered reel that feeds a strip loop from a pull-off reel whose downstream straightener draws material while a drag brake controls the reel. [3]
Are decoiler and uncoiler different machines?
Machine Concepts uses the terms synonymously for a mandrel machine that unwinds a coil into downstream processing equipment. [1]
Sources and evidence scope
Sources checked 2026-10-18. Machine Concepts supplies the mandrel and system-range context. Qiaosen describes a named motorized unit. COE distinguishes powered and pull-off architectures and lists available options. No capacity is transferred between these makers or from a whole range to the illustrated machine.
