Abstract: The leads of a lead frame on which an encapsulated chip is placed are bent by placing them in a mould and subsequently bending them with a bending tool in the form of a cylinder-like roller rotatable round a rotating shaft. Because the roller rolls off over the leads, scraping off of solder onto the leads is prevented during bending. In view of its length the mounting of such a roller causes problems, such as sagging. This is resolved according to the invention by providing the roller on the periphery with slot-like recesses for passage of a bearing for the rotating shaft.
