Claim:
1. An idler roll configured to engage in sliding engagement with and redirect a length of film moving across the idler roll, the idler roll comprising: a base having a generally cylindrical exterior surface with a center axis that defines mutually perpendicular axial and radial directions relative to the base, the base having an axial length with a base first end and a base second end at opposite ends of the axial length of the base; a plurality of wear strips, each wear strip having a length between one end of the wear strip and a second end of the wear strip, each wear strip being configured for removable attachment to the base by inserting the one end of the wear strip at the base first end and then sliding the wear strip along the axial length of the base to the base second end; an indexing shaft, the base being supported on the indexing shaft; a hub at one end of the indexing shaft; and, a release on the hub, the release being operable to selectively allow the base to move a fraction of a complete rotation of the base and then stop movement of the base and hold the base stationary to position selected wear strips to engage in sliding engagement with the length of film moving across the idler roll.
