Abstract
A device () for cleaning surfaces is provided utilizing a web () of a tackified sheet material movably secured between rollers () on the device () that enable the web () to be moved over the surface in opposite directions. The device () includes a supply roller () and a take-up roller () secured to opposed ends of the web () of adhesive sheet material, with at least one roller () including a biasing mechanism () disposed within the roller (). The web () can be engaged with the surface by passing over a number of idler rollers () positioned between the supply roller () and take-up roller (). The biasing mechanism () is designed to bias the movement of the web () onto the take-up roller (), such that the mechanism () can be selectively operated to advance the web () from the supply roller () to the take-up roller () to expose a clean section of the adhesive sheet material (). A synchronization mechanism () is also connected between the rollers () to enable the rollers () to rotate in a synchronous manner, regardless of the amount of the web () that is positioned on the rollers () to continually tension the web () a proper amount.
