US 5,804,030 A · Apparatus for making prestressed honeycomb

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.

Dependent claims

An apparatus for cutting and forming a resilient prestressed paper honeycomb structure of a predetermined size and shape in one step, the apparatus comprising:

a) means for cutting through a paper honeycomb structure comprising opposed hollow-cell faces defining planar surfaces along a predetermined line to form a predetermined shape;
b) at least one plate cooperatively associated with the cutting means, the plate being capable of compressing the paper honeycomb structure substantially continuously along at least one of its planar surfaces to form a resilient prestressed cushioned face portion;
and
c) means for simultaneously driving the cutting means through the honeycomb structure while laterally compressively deforming the selected planar surface to a predetermined depth, such that a prestressed honeycomb structure having a substantially continuous resilient cushioned planar surface is obtained.

An apparatus for forming a resilient prestressed honeycomb structure comprising:

a) a support frame;
b) a belt for conveying a honeycomb structure, the honeycomb structure including opposed hollow-cell faces defining opposed planar surfaces;
c) a roll frame positioned above the belt, the toll frame being mounted for pivotal displacement about the support frame;
d) a plurality of parallel and elongate compression rolls mounted on the roll frame for compressively deforming at least a portion of one of the planar surfaces of the honeycomb structure to form a resilient prestressed cushioned face portion as the honeycomb structure is conveyed past the compression rolls;
and
e) a roll height adjuster secured to the support frame and operatively associated with the roll frame for varying the vertical and angular displacement of the roll frame with respect to the support frame and positioning the compression rolls at different heights with respect to the support frame such that when the honeycomb structure is conveyed past the compression rolls, the compression rolls incrementally compress at least a portion of one of the planar surfaces to a predetermined depth to form the resilient prestressed cushioned face portion of a prestressed honeycomb structure.
