摘要：A device for preventing meandering or free running of a web on a rollsupported on a shaft on a machine, like a thermal printer. A stationary shaft is fixed tothe frame. A core is rotatably mounted around the shaft. A reel mounted around thecore has a carbon ribbon that is to be wound on it or unwound from it when the reel isrotated. A leaf spring between the core and the inner circumference of the reelfrictionally connects the reel and the core so that the reel does not rotate idly of thecore, but rotates together with the core. The core is held by a spacer at a predetermineddistance along the shaft from the machine frame. A spring acting on the opposite side ofthe core pushes the core toward the spacer, whereby the core is frictionally restrainedfrom freely rotating, which prevents web meander. Felt washers disposed between thecore and the elements axially adjacent thereto smooth the rotation of the core andprevent wear thereof.
