<p>The present invention relates to an apparatus for manufacturing a roll-type liquid silicone rubber foam having no surface viscosity and a thin film shape with a greatly reduced thickness of 0.2mm, which is capable of manufacturing a roll-type liquid silicone rubber foam having a predetermined width (300mm- 1,000mm) in a continuous process useful for mass production. The apparatus includes a first PET film-supplying unit, adapted to supply a first PET film having a predetermined width; a liquid silicone rubber- supplying unit, adapted to apply a liquid silicone rubber containing a foaming agent and a curing agent on a surface of the PET film, which is supplied from the first PET film- supplying unit; a second PET film-supplying unit, adapted to supply a second PET film having no stickiness on the liquid silicone rubber applied to the first PET film, which is transferred from the first PET film-supplying unit through the liquid silicone rubber-supplying unit; a second PET film-recovering unit, adapted to recover the second PET film transferred from the second PET film- supplying unit; a foaming and curing unit, positioned between the second PET film- supplying unit and the second PET film-recovering unit and adapted to foam and cure the liquid silicone rubber disposed between the first PET film and the second PET film and to control a thickness of the liquid silicone rubber which is being foamed; and a liquid silicone rubber foam-take-up unit, adapted to take up the liquid silicone rubber foam as the final product into a roll form, which is transferred from the foaming and curing unit during the recovery of the second PET film into the second PET film-recovering unit.</p> |
