Operating instruction manuals
The single roll steering roller assembly will be mounted at the exit of a scray or the conveyor prior to the entry into a print range. The web will be in a relaxed state. This guider assembly is used for pre-guiding prior to an SWA 7514 segmented roll guider.
One TR45 tracking roller assembly for pre-guiding prior to Zimmer print ranges, consisting of:
Model TR45 web guide system features an electrically actuated tracking roll assembly having a low friction roller bearing suspension system, assuring a fast, accurate response under medium web tension. The functional, easy to maintain design permits either a “U” or a “Z” type web path and fits easily into most applications
Model TR 4520 edge only guiding (style 2A) tracking roll assembly unit having two (2) 80” roll face by 6.25” diameter idlers and a correction span of 40”. The unit provides +/- 3” of correction for a web of 1850 mm (72” maximum width). The sensor is positioned for guiding by the right or left edge of the web
Rotodur covering for idler rolls
Model FR0901 edge sensor including required cable of 8 meters
Reflective tape on TR frame
Sensor mounting kit, including square bar and vernier adjustment bracket, to permit fine lateral sensor positioning
Amplifier control unit for style 2A, 45 watt actuator systems, mounted within a NEMA 12/13 enclosure, with model RE 2030 operator control station for the auto/manual/servo center function
