<p>An apparatus for the continuous production of an auxetic foam, comprising a tunnel (17) comprising a compression section with an inlet and an outlet for compressing foam in at least one axis as it moves from the inlet to the outlet, means (13, 14, 15, 16) to propel a foam material through the tunnel (17) from the inlet to the outlet, and heating means to heat foam passing through the compression section (11) to a temperature higher than its glass transition temperature.</p> |
