  • Method of infrared heating a restricted area on a continuous thermoplastic laminated web
    Patent number: 5113479
    Abstract: A method of heating a portion of a continuous material strip includes heating the web through use of one or more IR lamps provided with radiation-concentrating reflectors. The IR lamps are directed towards a restricted area on the web to thereby heat the thermoplastic surface in the restricted area to a temperature that corresponds to the melting temperature of the thermoplastic. The web can be provided with a color strip in the restricted area, whereby the color strip absorbs the heat from the IR lamps.
