ABSTRACT:
A method and a device for connecting objects by means of a connecting element which can be plasticised by heat, on which connecting element a rivet head is formed by means of a heatable cap having a small-volume configuration. The cap is heated by a heating element which is moveable together with it in the direction of the connecting element and is configured as a large-volume heat store. The heating element is separated from the cap after forming the rivet head but before withdrawal of the cap from the rivet head, in order to enable rapid cooling of the rivet head.
