Abstract
Abstract A feed arrangement for transporting a strip of recording material past a recording pen includes a feed roller and a positioning roller both drivingly engageable with the strip and driven in synchronism. The feed roller is located in advance of the positioning roller and feeds the strip material from a storage roll to the positioning roller. Slack in the strip of recording material is maintained between the feed roller and the positioning roller to remove from the portion of the strip engaged by the positioning roller all forces required to advance the strip of recording material from storage. The feed roller has sprocket pins which engage a first set of apertures along the edge of the recording strip, and the positioning roller also has sprocket pins which engage a second set of apertures along the edge of the recording strip. Since the pins of the positioning roller need exert only small forces on the engaged portion of the strip the possibility of such pins tearing or deforming the strip, with resulting inaccurate positioning of the strip, is eliminated or at least greatly reduced. The positioning roller may be a drum which also supports the recording strip for coaction with the recording pen.
