ABSTRACT:
The present invention is used for setting and bonding fasteners to support surfaces. The fasteners are provided with connecting surfaces which are coated with a dry hot-melt-type adhesive on the bare side thereof. The adhesive can be reactivated by means of heat treatment. The setting device includes a housing (1) having a receiving component (2) that is displaceably guided therein and is used for the fastener (3) as well as means for quickly heating the hot-melt-type adhesive, lowering the receiving component (2) and pressing the adherent (25) after the adhesive has been melt on. Heating is carried out by means of hot air (H) which is supplied passing the housing (1) and in that the receiving component (2) is surrounded by a closed wall (7) that extends from the hot air discharge location in the housing (1) to the fastener (3). The hot air (H) can thus be conveyed to the adhering hot-melt-type adhesive before or while the fastener (3) rests on the support surface (25).
