Abstract
Abstract A metal core is obtained from a continuous metallic strip, having proper characteristics as far as plasticity and ductility are concerned. This metal band or strip is die-cut to provide a reticulate structure formed by hexagons rather contracted lengthwise. These hexagons constitute a lineup in such longitudinal direction and, in a later phase, are subjected to a folding operation so that their larger sides similar to adjacent hexagons form the central portion of the channeled section, while the joints remain on the side portions of the channeled section. Besides, the side apices of these hexagons extend, forming small flaps which, in turn, make the joints in between take the center line of the mentioned side portions of the channeled sections.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
139 words
An improved metal core for sections of automobile and similar vehicles, which besides providing optimum results as regards stiffening effects, is intended to make sure that a weatherstrip is easily ductile in any direction within a plane perpendicular to its own axis and, having a slight shrinking ability, is not capable of being lengthened, comprising: said core being formed from a continuous strip of a metal and proper moulding and ductility, said core having a recticular shape formed by hexagons contracted lengthwise so that the two parallel and neighboring sides of each hexagon are much longer than other pairs of complementary sides, each pair constituting an acute angle, the die-cut strip is folded by two imaginary longitudinal lines touching the larger sides of the hexagons at points next to the side ends whereby said core assumes a U-shaped section.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
38 words
An improved metal core, as claimed in claim (1), 1 wherein the larger side of two adjacent hexagons is common to both hexagons, while the acute apices of the hexagons extend laterally to form a small rectangular flap.
Claim 4
Dependent Claim
22 words
An improved metal core as claimed in claims 2 or 1 wherein sides of the hexagon can be of the same width.
Claim 5
Dependent Claim
33 words
An improved metal core as claimed in claims 2 or 1, wherein the larger sides of each hexagon are substantially wider than the oblique sides and of same width as the end flaps.
