Abstract
Abstract A squeegee device applies material to a web substrate, which is guided across or held in contact with an abutment. The support body of the sequeegee contains a magnetic device extending along its longitudinal direction that holds a squeegee element made of magnetizable material. The squeegee edge is held against the substrate by the force of a magnetic device in the support body of the squeegee and a magnetic device under the abutment. In an alternative embodiment, no magnetic device is located under the abutment. However the abutment is made of ferrous metal to attract the magnetic device, causing pressure between the substrate and squeegee.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
80 words
An apparatus for applying application material to a substrate comprising: an abutment for supporting said substrate; a squeegee device having a support body, magnetic means inside said support body, and a squeegee element made of a magnetizable material held onto the said support body by said magnetic means; and said abutment being of a magnetically attractable material so that an attractive magnetic force is generated between said abutment and said squeegee device to press said squeegee element against said substrate.
Claim 2
Independent Claim
80 words
An apparatus for applying application material to a substrate comprising: an abutment for supporting said substrate; a squeegee device having a support body, magnetic means inside said support body, and a squeegee element made of a magnetizable material held onto the said support body by said magnetic means; and said abutment being of a magnetically attractable material so that an attractive magnetic force is generated between said abutment and said squeegee device to press said squeegee element against said substrate.
