Definitions
- the invention relates to a process for the manufacture of endless metal bands which have been made endless by means of welded joints.
- Such a process which is known from the U.S.-A-3,922,771, makes it possible to produce endless bands which can be applied as part of a composite metal driving belt.
- the object of the present invention is to afford a process whereby endless bands can be manufactured from plate metal in a simple fashion and with a minimum waste of material.
- a strip of plate metal is wound and welded together edge to edge in a helical shape so as to form a pipe whose length is equal to at least a multiple of the width of the desired metal bands, whereupon ring-shaped parts are servered from the pipe to obtain said endless metal bands.
- the length of the band may be increased by rolling, which also has a beneficial effect on the welding joint.
- the welding is preferably done by a method in which no additional metal is supplied.
