Patent ID: 7833369

Claim:
A process for making a composite, the process comprising the steps of: providing a first substrate; treating at least a portion of the first substrate with an adhesive having a softening point lower than the softening point of the first substrate; allowing the adhesive to set such that the adhesive is no longer tacky; winding the treated first substrate to form a roll; thereafter unwinding the treated first substrate; inputting energy to the unwound, treated first substrate, thereby activating at least a portion of the adhesive coated on the first substrate, wherein the input of energy is effected before, concurrent to, or after the first substrate is brought into contact with a second substrate; providing the second substrate; joining at least a portion of the first substrate to at least a portion of the second substrate to form a composite, wherein the first substrate and second substrate are joined at least in part by the activated adhesive.
