摘要
A method for producing an upholstery spring, such as for upholstered furniture or mattresses includes several steps. One of the steps includes at least regionally applying a heat-sensitive colour indicator to a spring steel wire before, during or after the bending of the spring steel wire. The spring steel wire is heated to at least the changeover temperature of the colour indicator. The upholstery spring is then finished.
