Set of panels with mechanical positioning means

Abstract

A set of rectangular building panels have a frontside and a backside and a mechanical locking device at opposite first and second edge portion configured for plane locking of similar panels in an assembled position by displacement of a plane with a second edge portion of a second panel in an engagement direction towards a first edge portion of an adjacent first panel. The first edge portion includes a first locking element configured to cooperate for plane locking with a first locking groove at the second edge portion. The first edge portion has a first front edge portion adjacent the frontside of the first panel and a first sub edge portion between the first front edge portion and a flexible tongue in an insertion groove, the insertion groove being arranged between the backside of the first panel and the first sub edge portion.
