Transform your 3'' expanding shaft into 6'' one

Adaptor 3'' - 6''

Transform your 3'' expanding shaft into 6'' one

Universal adaptor Corexal®

Transform in few seconds only your 3'' expanding shaft into 6'' one!


Expandable or mecanic shafts help supporting a coardboard core during the winding operation: the internal diameter is generally 3'' (76.2mm). It is however necessary to rewind on mandrels with internal diameter 6'' (152.4mm). With current solutions, you need to adjust adpators and expandable shafts, but they are heavy and fragile, and require pneumatic tubing.

Developed to respond to winding mandrels users' needs of quick and easy mounting, Corexal® allows to transform in few seconds only the 3'' expanding shaft into 6'' one without any tubing, mounting nor tools.

Our Corexal ® is the ideal component to adapt your manufacturing process to your customer's bobins.

When expanded, the 3'' shafts opens the adpator which then holds the 6'' cardboard core. A spring enables to remove the cardboard core after deflating of the expandable shaft.    

Our Corexal® can be used alone (for small width webs) or by pair. It brings no damage of the expanding shaft and no specific tools are needed to install it. Manufactured in aluminium profile, our Corexal® is alsolight either mounted. Light, easy and quickly installed, Corexal® eases all shafts maintenance and handling operations.

Used mainly for labels printing and webs converting, this adaptor is available on stock in different lengths (standard of 300 mm or on request) and delivered in less than 1 week!
