## Abstract

An apparatus and process for the delivery of material to rolls of a laminator is disclosed.

## Claims

### Claim 1

An apparatus for dispensing material between two rolls of a laminator comprising:
a) at least two reactant storage tanks, each reactant storage tank having a gear pump;
b) a mixer connected to the gear pumps;
c) a dispensing nozzle connected to the mixer;
d) a level detector mounted on a rail configured to be between the two rolls of the laminator; and
e) at least one solvent storage container connected to the mixer.

### Claim 2 (depends on 1)

The apparatus of claim 1 wherein the level detector is electronically connected to the gear pumps of the reactant storage tanks.

### Claim 3 (depends on 1)

The apparatus of claim 1 wherein the mixer has a mixing speed in the range of from 1000 rpm to 8000 rpm.

### Claim 4 (depends on 1)

A laminator apparatus comprising a plurality of rolls and further comprising the apparatus of claim 1.
