TIP F 1421 Draglink Gear General Overhaul

Machine Model for Improvement

All Bielomatik Folio-Size Sheeters with Draglink

Description of Improvement

Over time, after years of intensive daily, round-the-clock production, draglink unit parts wear out. As a result, knife life becomes shorter and cut quality deteriorates can occur.

This TIP module provides a complete overhaul of the draglink gear at a BW Papersystems facility in Germany, where all the required special precision machinery, tools, measuring equipment and expertise are available.

The exchanged bearings and parts of the draglink gear cause less vibrations and reduced noise emissions. The new bearings at the double lever (see picture) allow an improved sheet length accuracy.

During a general overhaul the draglink gear unit is completely dismantled, thoroughly checked, cleaned and all wear and tear parts will be replaced. All the mechanic guide rails and guide plates of the draglink mechanism will be overhauled in our in-house machine shop.

Note: This general overhaul package does not include new knife shafts and new draglink gear wheels.

Benefits

• Improved operational availability and improved sheet length accuracy
• Smoother machine run with reduced noise emission & vibration
• Exchange of all wear & tear parts reduces maintenance costs
