## Abstract

Induction heating of a pattern perforated rotating cylinder susceptor is utilized to melt and apply thermoplastic materials to a substrate.

## Claims

### Claim 1

A method of applying pelletized thermoplastic materials consisting of the following:
inducing current into a perforated steel cylinder susceptor containing pelletized thermoplastic materials to melt with a bar shaped induction heating coil;
positioning said induction heating coil in appropriate proximity to said perforated steel cylinder susceptor; and
contacting a moving substrate with said perforated steel cylinder susceptor to progressively apply a melted pelletized thermoplastic materials.

### Claim 2 (depends on 1)

The method according to claim 1, having a continuous of said moving substrate presented to a rotating surface of said perforated steel cylinder susceptor for a variable peripheral distance to control a time that the moving substrate is in contact with the melted pelletized thermoplastic materials.

### Claim 3

A method of melting and applying pelletized thermoplastic materials consisting of the following:
rotating a pattern perforated steel susceptor containing pelletized thermoplastic materials;
inducing current into said pattern perforated steel cylinder susceptor to melt pelletized thermoplastic materials with a bar shaped induction heating coil;
positioning said bar shaped induction heating coil in appropriate proximity to said pattern perforated steel cylinder susceptor; and
contacting a substrate with said pattern perforated steel cylinder susceptor to progressively apply a melted pelletized thermoplastic materials.

### Claim 4 (depends on 3)

The method according to claim 3, that applies pressure with said pattern perforated steel cylinder susceptor for laminating a multi-layer substrate.

### Claim 5 (depends on 3)

The method according to claim 3, wherein a spring loaded pressure roll applies pressure to the substrate to assure full contact with said pattern perforated steel cylinder susceptor.

### Claim 6 (depends on 3)

The method according to claim 3, having the substrate contact said pattern perforated steel cylinder susceptor at a variable radial distance from said bar shaped induction heating coil to control a time that the substrate is in contact with the melted pelletized thermoplastic materials.
