Abstract
An apparatus for forming a resilient prestressed honeycomb structure from a honeycomb structure having opposed hollow-ell faces defining opposed planar surfaces. The apparatus comprises a conveyor for conveying the honeycomb structure and a compression apparatus for compressively deforming at least a portion of the honeycomb structure. When the honeycomb structure is conveyed past the compression apparatus, the compression apparatus compressively deforms one of the planar surfaces of the honeycomb structure to form a resilient prestressed cushioned face portion. The compression apparatus comprises a plurality of parallel and elongate compression rolls for compressively deforming the honeycomb structure to form the resilient prestressed cushioned face portion. The compression apparatus further comprises a roll height adjuster for positioning the compression rolls at different heights to incrementally compress the planar surfaces of the honeycomb structure when the honeycomb structure is conveyed past the compression rolls.
