Rosback 250F 3-Knife Trimmers

Print Literature - in PDF Format

The 250F Trimmer is basically the same as the 318 Trimmer. The main difference between the 318 and 250F Trimmer is that the 250F Trimmer is equipped with a variable speed inverter drive.  The 318 Trimmer is mechanically timed to the Stitcher.  The inverter drive feature on the 250F Trimmer helps the automated timing sequence from the Stitcher.  The complete Saddle Bindery System speed can now be adjusted by a single twist of a dial.
