Abstract
Abstract A supply roll of gauze or similar material in the form of a continuous web is enclosed within a heated chamber and passed through medication in viscous form so as to place it on the moving web within the heating chamber. The medication is distributed throughout the gauze so as to impregnate the gauze and the gauze web is then moved through a cooling chamber to solidify the medication. The medication impregnated web is then cut into sections of a predetermined length and each of the sections are folded. The folded section is then inserted into a flat package and sealed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
81 words
In a method of making a medicated pad package, the steps of applying medication in a viscous state to gauze in a single web, quickly cooling the medication and gauze by subjecting the medication and gauze to sub-zero temperature to solidify the medication in a homogenous condition on the gauge so as to place a predetermined amount per unit area of medication on said gauze, thereafter placing the gauze with medication applied thereto into an envelope-like package, and sealing the package.
Claim 2
Dependent Claim
