Prevent breaking the border of the rubber

Too often I break the border of the rubber.

Last time in the second training session of my new,expensive, rubbers.

It happens when pushing with backspin (chopping on the table ?)

What can I do to prevent this to happen regarding glue, cutting etc?

Thanks a lot Jeff, Alois.

Hi Jesus-Cristobal,

This is a hazard of the rubber.  A good idea is to put some wide sidetape on the racket that covers the side of the rubber as well.

This will help a bit but the rubber can still get damaged with pushing and hitting the bat on the table.
