Electrically heated bread toaster - is made by stretching and bending metal strip after cutting or punching

摘要

The toasting chamber is enclosed by a shaped metal guard protecting the heater body. The toaster or the guard are made by punching or making cuts in a metal strip (1), which is then stretched and/or bent in separate areas into the final and larger shape. It can consist of a single metal component in which cuts are made at right angles to the stretching direction before stretching takes place. When this has been done, heat radiation openings are formed in it of rhombic or rectangular shape. There can be an anchoring strip (3) joined to one side of the metal component and running parallel to the cuts (4) in it.
