Material application system
View Patent ↗A system for applying a material to a substrate comprising: a feed section that comprises a feed roll and configured for advancing a material along a predetermined path; a material applicator roll configured to receive the material from the feed roll and apply a cut length of material to a substrate; a knife element located between the feed section and the material applicator roll; and a non-vacuum anvil roll positioned near the knife element, wherein the knife element and the non-vacuum anvil roll are positioned along the path of the material and engage the material to cut the material into the cut length of material for applying to the substrate, and wherein the material contacts the peripheral surface of the non-vacuum anvil roll only at a cut engagement point.
1. A system for applying a material to a substrate comprising:
a feed section that comprises a feed roll and configured for advancing a material along a predetermined path;
a material applicator roll configured to receive the material from the feed roll and apply a cut length of material to a substrate, wherein the material applicator roll comprises a vacuum roll defining a peripheral surface having a contoured portion forming a convex shape;
a knife element located between the feed section and the material applicator roll; and
a non-vacuum anvil roll positioned near the knife element.
2. The system of claim 1 , further comprising a first drive for the feed roll, a second drive for the knife element, and a third drive for the material applicator roll.
3. The system of claim 2 , wherein the first drive comprises a first motor, the second drive comprises a second motor, and the third drive comprises a third motor.
4. The system of claim 1 , wherein the knife element comprises a knife roll.
5. A system for applying a material to a substrate comprising:
a feed section that comprises a feed roll and configured for advancing a material along a predetermined path;
a material applicator roll configured to receive the material from the feed roll and apply a cut length of material to a substrate, wherein the material applicator roll comprises a vacuum roll defining a peripheral surface having a contoured portion forming a convex shape;
a knife element located between the feed section and the material applicator roll; and
a non-vacuum anvil roll positioned near the knife element; and
an element forming a nip with the material applicator roll, wherein the element defines a peripheral surface, wherein the peripheral surface has a concave portion that conforms to the convex shape of the material applicator roll.
6. The system of claim 5 , further comprising a first drive for the feed roll, a second drive for the knife element, and a third drive for the material applicator roll.
7. The system of claim 5 , wherein the knife element comprises a knife roll.
8. A system for applying a material to a substrate comprising:
a feed section that comprises a feed roll and configured for advancing a material along a predetermined path;
a material applicator roll configured to receive the material from the feed roll and apply a cut length of material to a substrate, wherein the material applicator roll comprises a vacuum roll defining a peripheral surface having a contoured portion forming a concave shape located between a first end of a first elevated section and a first end of a second elevated section and wherein the vacuum roll peripheral surface further includes a recessed portion opposite the concave shape and contiguously spanning between a second end of the first elevated section and a second end of the second elevated section;
a knife element located between the feed section and the material applicator roll; and a non-vacuum anvil roll positioned near the knife element.
