Mechanical coil element has at least two windings made of strip, tube or wire material formed into spirals and alternately wound from out to in and from in to out

摘要

The coil element consists of at least two windings (1,2) of uninterrupted, continues strip, tube or wire material, each with starting and end pieces (A,E). The windings are made of strip, tube or wire material formed into spirals alternately wound from out to in and in to out. The overall height of the coil element is made up by the addition of the individual coil heights measured in the coil direction plus the width of the isolation materials. Independent claims are also included for the following: a method of manufacturing a mechanical coil element.
