ELTrac Single Facer Guiding System

• Reduced paper waste
• Reduced trimming / max. width utilization
• Glue application across the entire web width
• Shortened machine downtimes

The ELTrac Single Facer Guiding System ensures automatic, accurate and instantaneous alignment of the papers in the single faced web which creates the correct conditions for the slitter scorer to run with the minimum side trim width. Automation of the alignment process at the single facer allows the operator to focus on the production of the single faced web and prepare the reels and splicers for the next reel change.

Due the many differing layouts of single facers and surrounding equipment, the ELTrac system is available in two variants, as explained below. Furthermore, both systems can utilise either a Vertical or Cube ELTrac Guiding Unit, which can be installed in a number of differing positions and orientations to facilitate integration into the corrugator whilst providing exactly the same functionality and system performance.

ELTrac Solo Single Facer Guiding System

The ELTrac Solo System comprises of a Flute Paper Detection Unit which constantly monitors the lateral position of the fl ute paper and an ELTrac Liner Paper Guiding Unit which is integrated into the path of liner paper. Automatic guiding of the liner paper to the position of the fl ute paper results in an accurately aligned single faced web.

ELTrac Duo Single Facer Guiding System

When space exists, an ELTrac Flute Paper Guiding Unit can be integrated into the flute paper path. In addition to the features of the ELTrac Solo System, the ELTrac Duo System also ensures that a full width glue application can be made, without the risk of starch transfer onto the corrugating rolls.
