METHOD OF APPLYING THERMOPLASTIC RESIN TO NON-HEAT RESISTING FILM AND DEVICE FOR EXECUTING THE METHOD

Japanese Patent JP3329499

B2

PURPOSE: To apply thermoplastic resin to a non-heat resisting film not subjected to any special treatment without fusion and shrinkage by applying fused thermoplastic resin at designated spaces on the separation treated transport surface, moving and transporting the same while cooling, and transferring the same to a non-heat resisting film.
CONSTITUTION: The surface of a rotor in a driving part 1 forms a transport surface 3, and a liquid circulating pipe 8 is connected to a cavity 5 provided in the interior to form a temperature control means for the transport surface 3. An application part 2 applies fused thermoplastic resin 6 at designated spaces on the transport surface 3, and as a non-heat resisting film, a continuous sheet 7 of a packing material for a sanitary napkin is moved with the rotation of the driving part 1. In this case, the transport surface 3 is smooth and subjected to release finishing, and the applied thermoplastic resin 6 is cooled by the movement of the transport surface 3 and transported to be transferred to the continuous sheet 7 as a non-heat resisting film. A sanitary napkin 21 is placed thereon and wrapped from both sides by the continuous sheet 7, and thereafter.
