Multispool

Multispool is a term used in engineering to describe a device or system that uses multiple spools to hold and feed flexible media such as wire, filament, fiber, or tape. The arrangement enables simultaneous handling of several material streams or rapid material switching.

Design and operation: A multispool assembly typically features a central drive or multiple drives turning each spool independently or in coordination. Spools may be arranged in a circular carousel, a linear rack, or a stacked frame. Common features include tension control, braking, and sensors to monitor rotation and prevent tangling.

Applications: In textile production, multispool winders support multi-color thread feeds. In electronics and cabling, they allow switching between conductors. In additive manufacturing and automation, they enable automatic spooling of filaments or fibers, reducing downtime and manual intervention.

Variants: Configurations range from concentric designs with separate layers on a single core to parallel arrays of independent spindles. Some systems use centralized control for synchronized feeding; others employ distributed controllers. Modular, swappable frames facilitate scaling the number of spools.

Advantages and limitations: The approach can reduce changeover time and increase throughput, but adds mechanical complexity, cost, and maintenance needs. Proper tension management and spool control are essential to prevent slippage, tangling, and uneven feed.
