Abstract
In case of manufacturing tear-off lids (28) out of lid rings (20′) with a tear-off foil (25) sealed on them and with a tear-off tab (29) the tear-off tab is fixed in a folded back position onto the tear-off foil of the lid by an adhesive patch (30). For this, the adhesive patch is applied onto the foil section in such a way that individual adhesive patches are separated out of an adhesive tape with a carrier tape and an adhesive material arranged thereon by a separating means. Such an adhesive patch is arranged on the foil section of each lid in a position where the folded back tear-off tab comes to lie. By this, a fixing of the tear-off tab can be reached in an economical and secure manner.
