摘要：A mechanism for maintaining a moving web (2) of sheet material in its proper path along an edge guide (10) in an apparatus such as a photographic printer. A compliant roller (12) is mounted on a roller shaft (14) which is pivoted at each end (16) to a linkage (18) which is itself pivoted relative to a stationary frame (8). This articulated linkage (16, 18) permits the roller (12) to find its natural stable position, rolling on the moving web (2) such that its axis, the roller shaft (14), is substantially perpendicular to the travel path (5) of the web (2). A tension spring (24) between frame (8) and linkage (18) biases the roller (12) and the web (2) toward its desired position along the edge guide (10).
