Method for producing materials of honeycomb structure

Claim 1

A METHOD OF FORMING AN ELONGATED SUBSTANTIALLY RIGID STRUCTURE FORMED WITH CLOSELY SPACED PARALLEL BORES THERETHROUGH IN A CONTINUOUS PROCESS COMPRISING THE STEPS OF MOVING A SOFT HARDENABLE MATERIAL IN ONE DIRECTION; MOVING A PLURALITY OF COMBS HAVING EACH A PLURALITY OF SUBSTANTIALLY PARALLEL PINS CLOSELY SPACED FROM EACH OTHER IN A DIRECTION TRANSVERSE TO THE ONE DIRECTION IN SAID ONE DIRECTION AND INDIVIDUALLY RELATIVE TO EACH OTHER AND TO SAID MATERIAL WHILE MAINTAINING THE PINS OF ADJACENT COMBS PARALLEL TO EACH OTHER AND TO THE AXES OF THE BORES TO BE FORMED IN SUCH A MANNER THAT FREE END PORTIONS OF SAID PINS BECOME EMBEDDED IN SAID MATERIAL; MOVING SUBSEQUENTLY THERETO SAID MATERIAL AND SAID COMBS IN SAID ONE DIRECTION WHILE MAINTAINING THE POSITION OF SAID COMBS RELATIVE TO THE MATERIAL AND WHILE THE LATTER HARDENS ABOUT THE PINS OF SAID COMBS; AND WITHDRAWING EACH COMB INDIVIDUALLY IN DIRECTION OF THE AXES OF ITS PINS AND PARALLEL TO THE AXES OF THE BORES THUS FORMED FROM THE HARDENED MATERIAL TO FORM A SUBSTANTIALLY RIGID STRUCTURE WITH CLOSELY SPACED PARALLEL BORES THERETHROUGH, WHEREBY THE MATERIAL ABOUT SAID BORES WILL NOT BE DAMAGED DURING THE WITHDRAWAL OF THE PINS THEREFROM.

Claim 2

A METHOD OF FORMING AN ELONGATED SUBSTANTIALLY RIGID STRUCTURE FORMED WITH CLOSELY SPACED PARALLEL BORES THERETHROUGH IN A CONTINUOUS PROCESS COMPRISING THE STEPS OF MOVING A SOFT HARDENABLE MATERIAL IN ONE DIRECTION; MOVING A PLURALITY OF COMBS HAVING EACH A PLURALITY OF SUBSTANTIALLY PARALLEL PINS CLOSELY SPACED FROM EACH OTHER IN A DIRECTION TRANSVERSE TO THE ONE DIRECTION IN SAID ONE DIRECTION AND INDIVIDUALLY RELATIVE TO EACH OTHER AND TO SAID MATERIAL WHILE MAINTAINING THE PINS OF ADJACENT COMBS PARALLEL TO EACH OTHER AND TO THE AXES OF THE BORES TO BE FORMED IN SUCH A MANNER THAT FREE END PORTIONS OF SAID PINS BECOME EMBEDDED IN SAID MATERIAL; MOVING SUBSEQUENTLY THERETO SAID MATERIAL AND SAID COMBS IN SAID ONE DIRECTION WHILE MAINTAINING THE POSITION OF SAID COMBS RELATIVE TO THE MATERIAL AND WHILE THE LATTER HARDENS ABOUT THE PINS OF SAID COMBS; AND WITHDRAWING EACH COMB INDIVIDUALLY IN DIRECTION OF THE AXES OF ITS PINS AND PARALLEL TO THE AXES OF THE BORES THUS FORMED FROM THE HARDENED MATERIAL TO FORM A SUBSTANTIALLY RIGID STRUCTURE WITH CLOSELY SPACED PARALLEL BORES THERETHROUGH, WHEREBY THE MATERIAL ABOUT SAID BORES WILL NOT BE DAMAGED DURING THE WITHDRAWAL OF THE PINS THEREFROM.
