Abstract
A method for producing a shaped profile section in a continuous line process provides providing an outer facing web, an inner facing web and laying down an liquid foam reactants in the outer facing web. The method pre-forms the outer facing web into a desired outer profile shape prior to laying down the liquid foam reactants. The inner facing web is shaped with the liquid foam reactants within the pre-formed outer facing web to provide a desired inner profile shape for the shaped profile section. Also provided is an apparatus for producing a shaped profile section and a shaped profile section of the method.
Claims13
A method for producing a shaped profile section in a continuous line process, the method comprising steps of:
- providing an outer facing web;
- laying down liquid foam reactants in the outer facing web;
- engaging an inner facing web with the outer facing web;
- pre-forming the outer facing web into a desired outer profile shape prior to laying down the reactants;
- and
- pre-forming the inner facing web into a desired inner profile shape for the shaped profile section prior to engagement with the outer facing web, the pre-formed inner facing web maintains its shape in the absence of support from an external structure, after the step of pre-forming the inner facing web is complete.
