Kardborrbands

Kardborrbands are belts used in carding machines to transmit power and synchronize the movement of carding drums and related components. The term appears in Swedish-language textile literature and describes flat drive bands that fit around pulleys on a carding frame, enabling the rotation of the carding cylinders during fiber processing.

Etymology and scope

The word is a compound construction likely rooted in Swedish, combining carding (kard) with belt or band (bands/band). In historical and workshop sources, kardborrbands refer to the drive or transfer bands employed in traditional carding setups, rather than to the carding teeth or drums themselves.

Function and design

Kardborrbands serve as a mechanical link between pulleys to convey rotational motion and, in some configurations, to ensure proper speed ratio and timing between carding elements. They are typically designed to withstand fiber dust, tension, and wear, and their width and material depend on the specific carding machine model. In older equipment, multiple bands or layered constructions may be described to achieve adequate drive capacity.

Materials and maintenance

Construction materials commonly include leather or fabric with a rubberized surface, chosen for grip and durability. Regular maintenance involves checking tension, inspecting for cracking or glazing, cleaning to remove fiber buildup, and replacing worn belts to prevent slippage and damage to the carding process.

Historical context and modern status

Leather or fabric belts were widely used in traditional carding machinery before the prevalence of electric drives and roller or gear-based systems. In modern industrial carding lines, kardborrbands have largely been supplanted by more durable and maintenance-efficient drive methods, though the term may persist in archival texts and among traditional textile artisans.
