Accumulators

Accumulators are provided to allow the dipping machine to run continuously while splicing or doffing new rolls. The Letoff accumulator is normally 2-3 minutes and the windup accumulator is normally 1.5-2 minutes. Litzler believes that a single accumulator is more efficient and lower maintenance than tandem accumulators.

Litzler accumulators include multiple design features to improve the process

• High strength structural frames to withstand the tension loading from up to 300 meters of high strength tire cord – the tire cord imposes large stress on the frame and Litzler accumulators are designed to maintain precise alignment for the life of the machine
• Low friction deadshaft idler rolls – deadshaft rolls ensure low tension operation to minimize the fabric neck-down through the accumulator
• Energy saving hydraulic power units for precise carriage travel and control
• Internal load cell for tension monitoring in the accumulator. This information is linked to the LHMI for alarms and data acquisition
• Internal guiding and spreading systems on high speed machines to maintain width setpoint and improve quality
• Internal bow rolls are available for gentle spreading in lieu of low tension spreaders
