Abstract
Abstract A process for making synthetic resin structures in which the double wall element of a synthetic resin is molded with a channel open on one side of the element and into which a reinforcing body is fitted so that the walls of the channel flank this body. Each wall of the channel is provided with a row of openings, preferably extending in the longitudinal direction of the channel, the openings of each row registering with a respective groove formed in the reinforcement body. A cap or cover is molded over the open side of the channel so that portions of the synthetic resin of the cover can penetrate the openings and the grooves which can have a dovetail cross section.
