Abstract
Official abstract text for this publication.
An automatically-adjusting tensioning mechanism for use in a roll-fed web media transport system, the tensioning mechanism adding tension to the web media, comprising a bracket assembly being adapted to freely pivot around a pivot axis, and first and second tensioning shoe having curved surfaces attached to the bracket assembly. The web media feeds through the tensioning mechanism in an S-shaped media path where the web media is wrapped around the first and second tensioning shoes. The pivot angle of the bracket assembly automatically adjusts in response to differences in a coefficient of friction between the web media and the tensioning shoes such that the tension in the web media has a reduced level of variability relative to configurations where the bracket assembly is held in a fixed position.
First claim
Opening claim text (preview).
The invention claimed is: 1. An automatically-adjusting tensioning mechanism for use in a roll-fed web media transport system, the tensioning mechanism adding tension to the web media, the web media having a width, comprising: a bracket assembly mounted to a frame, the bracket assembly being adapted to freely pivot around a pivot axis through a range of pivot angles, the pivot axis being oriented in a direction across the width of the web media; a first tensioning shoe extending…
