Method for producing a spring for an undercovering of a mangle roller, an undercovering and a spring

摘要

The method involves forming a spring (15) from a blank of spring steel by punching. A resulting ridge, during the punching of each spring, is partially dismantled by cold deformation. The ridge is dismantled in a border area, particularly at the entire peripheral edge region. Independent claims are also included for the following: (1) an undercovering for a deficiency roller; and (2) a spring for an undercovering of a deficiency roller.
