Abstract
A hot laminating apparatus has a single-sided transmitting and heating roller. A heating plate is used instead of a transmitting and heating roller at the opposite side of the transmission passage in order to heat the thin film in contact therewith and cooperate with the single-sided transmitting and heating roller to transmit the thin films to be laminated. The heating plate is efficient in heating the thin film and generally less expensive than the transmitting and heating roller.
Claims17
A hot laminating apparatus having a transmission passage for passing therethrough a sheet material and thin films to be hot laminated, comprising:
- a still heating member disposed at a first side of said transmission passage for heating a first one of said thin films in contact therewith;
- and
- a transmitting and heating roller disposed at a second side of said transmission passage for heating a second one of said thin films in contact therewith, and rotating relative to and cooperating with said heating member to transmit said thin films through said transmission passage while pressing said thin films to be laminated.
A hot laminating apparatus for laminating a sheet material between thin films, comprising:
- a heating plate having a heater at a first free end and a heat-conducting plate at a second free end;
- and
- a transmitting and heating roller cooperating with said heat-conducting plate to clamp said thin films and rotating to move relative to said thin films so as to heat and laminate different area of said thin films.
