Abstract
An apparatus for bending leaf-spring blanks is combined with a vessel containing a bath of a hot treatment liquid and defining a longitudinal treatment path below a surface of the liquid, a center guide extending longitudinally along the path in the bath, and a pair of side guides extending longitudinally along the path and spacedly horizontally flanking the center guide. Each guide has an upper element and a lower element spaced therebelow. A loader engages the blank in the bending apparatus generally centrally for removing the engaged blank form the bending apparatus, and for depositing the blank in the bath between the upper and lower guide elements. In addition a conveyor including center and side pushers is displaceable longitudinally along each of the respective guides for engaging the blank engaged therein and displacing same along the path through the guides between the upper and lower elements.
