Abstract
The rotary anvils herein may be used in combination with a tool member to perform various types of manufacturing operations, such as cutting, bonding, and embossing. The anvil roll may include a cylindrically-shaped outer circumferential surface and may be adapted to rotate about a first axis of rotation. More particularly, the anvil roll may include a body formed from a first material, such as a metallic material. The body may also include grooves in the outer circumferential surface, and abrasion resistant material may be fused to the body to fill the grooves to form strips. During operation, a tool member may be positioned to contact the strips of abrasion resistant material.
Claims29
An apparatus comprising:
- an anvil roll comprising an outer circumferential surface and adapted to rotate about a first axis of rotation, the anvil roll comprising:
- a body consisting of a first material, wherein the first material is selected from the group consisting of:
- an iron alloy, an aluminum alloy, and a titanium alloy, and wherein the body comprises:
- a groove;
- and
- one or more abrasion resistant materials fused to the body and filling the groove to form a strip, the one or more abrasion resistant materials being different from the first material;
- wherein a first portion of the outer circumferential surface of the anvil roll is defined by the strip;
- a tool member adjacent the anvil roll and adapted to rotate about a second axis of rotation and to contact the first portion of the outer circumferential surface of the anvil roll.
An apparatus comprising:
- an anvil roll comprising a cylindrically-shaped outer circumferential surface and adapted to rotate about a first axis of rotation, the anvil roll comprising:
- a body consisting of a first material, wherein the first material is selected from the group consisting of:
- an iron alloy, an aluminum alloy, and a titanium alloy, and wherein the body comprises:
- a first row of holes in the outer circumferential surface, each hole extending radially inward from the outer circumferential surface, wherein the first row extends in an axial direction;
- a second row of holes in the outer circumferential surface, each hole extending radially inward from the outer circumferential surface, wherein the second row extends in the axial direction;
- and
- a groove separating the first row of holes from the second row of holes;
- one or more abrasion resistant materials fused to the body and filling the groove to form a strip, the one or more abrasion resistant materials being different from the first material;
- wherein a first portion of the outer circumferential surface of the anvil roll is defined by the abrasion resistant material and a second portion of the outer circumferential surface is defined by the body;
- a vacuum pressure source in fluid communication with at least one of the first row of holes and the second row of holes;
- and
- a tool member adjacent the anvil roll and adapted to rotate about a second axis of rotation and contact the first portion of the outer circumferential surface of the anvil roll.
A method for making an anvil roll, the method comprising the steps of:
- providing a cylindrically-shaped body consisting of a first material, wherein the first material is selected from the group consisting of:
- an iron alloy, an aluminum alloy, and a titanium alloy, and wherein the body comprises an outer circumferential surface;
- machining a groove into the outer circumferential surface of the body;
- filling the groove with one or more abrasion resistant materials, the one or more abrasion resistant materials being different from the first material;
- and
- fusing the one or more abrasion resistant materials to the body in the groove.
