<p num="1"><br/><br/><br/>The invention relates to a blind rivet and a device for placing said rivet. <br/>The blind rivet contains a rivet head with a collar at one end and a rivet tip <br/>at the other. The rivet body contains a cavity in the form of a bore in a <br/>sleeve section. As with other blind rivets, the blind rivet is inserted into <br/>an opening in two sheets that are to be joined together, until the collar <br/>comes to rest on the upper face of the upper sheet. In a second step, the part <br/>of the rivet body or the rivet head that lies on the rear face of the two <br/>sheets is deformed with the aid of a hammer or expanding body, which is <br/>advanced with a percussive-type action in the same direction. A device for <br/>placing a rivet of this type contains a part that can be pushed forwards with <br/>a percussive-type action, said part consisting of a hammer for exerting <br/>pressure on the expansion body.<br/> |
