Embossing thermoplastic film laminates - combined films are heated, embossed and cooled by separately driven thermostatically controlled rollers

摘要

Thermoplastic films, film/fabrics, or film/papers etc. are laminated and embossed by heating and passing through sets of small dia. rollers which are close together and whose surfaces ensure accurate traction of the films; the rollers are driven separately and their temps. are controlled so as to ensure gradual and continuous heating for the material. There is no harmful slippage between material and roller, no width changes caused, and no thickness changes.
