Mechanical Dual-Roller Distance Counter

A purpose-built mechanical solution for measuring linear length on flexible, roll-fed materials such as woven textiles, digital prints, and imitation leather. Its dual-roller configuration ensures balanced ground contact and minimises slippage, while the metal-and-plastic chassis provides rigidity without excess weight. Measuring roughly 160 mm in length, it supports counting ranges from 1 to 99,999 meters and operates reliably at speeds up to 200 counts per minute. The internal mechanism locks after three complete wheel revolutions to prevent retroactive counting errors, and resets fully to zero for subsequent measurements. Accuracy is rated at ±1–3 cm — consistent with physical wheel-based metrology tools used across UK and EU industrial supply chains. No power source is required; all functionality is delivered through precision-machined gears and dials.
