Turret rewind core pinning

PROBLEM

Traditional methods of web changes are to use adhesive tape wrapped around the core to bond the lead end of the web to the core during change over.  

Static charges can be used to bond the lead edge of the web to the core, but due to the direction of rewind being clockwise or anticlockwise, this can be difficult due to available space. 

SOLUTION

Applying a static charge to the web as it passes over a grounded roller just prior to the splicing arm offers a solution.  The pre-charged material will follow the web path up to the point the knife cuts the web. The static charge is then attracted to the cardboard core that is held in contact by the lay-on roller.
