Convertech introduces air roll lock differential shaft

With converters looking for progressively more effective ways to increase productivity and reduce downtime, the advent of a more effective air roll lock differential shaft design from Convertech, Inc. is ‘a welcome addition to the wide and narrow web converting industry’, said the company in a statement.

GlideLock Clutched Rollers are ‘the secret behind this shaft's unique ability to perform flawlessly under a variety of material tensions and core sizes all on the same shaft’ continued the statement. Using an internally clutched mechanism to control multiple width cores on the same shaft, this differential shaft is able to deliver perfect tension control, on sensitive materials, without operator intervention. 

GlideLock Clutched Rollers ‘sense’ the width of each core and lock the core firmly in place preventing side to side movement, slippage, and core dusting. The internal clutching mechanism then precisely controls the material tension as the shaft turns. Each GlideLock Clutched Roller independently determines the proper positive tension to apply to the material, and then works with other rollers in proximity to grip the core tightly. 

When the correct positive tension has been applied to the material, the internal clutching mechanism acts to reduce the web strain accordingly to keep the tension at its optimal level for the material on the core.
