Abstract
A roller tube including a body having a tube wall that defines an interior and an exterior. The body includes a first end and a second end opposite the first end. A surface feature is formed in the tube wall proximate the exterior. The surface feature is configured to receive a sheet material and is configured to deformably fix the sheet material to the tube wall. The surface feature maintains a circular profile in the tube wall proximate the interior.
Claims30
A roller tube comprising:
- a body having a tube wall defining an interior and an exterior, said body including a first end and a second end opposite said first end;
- and
- a surface feature including a flange extending from a groove formed in said tube wall proximate said exterior, said surface feature configured to receive and fix sheet material to said tube wall;
- said flange being deformable and configured to substantially close over said groove to secure sheet material to said tube wall exterior;
- wherein said surface feature allows a generally circular profile to be maintained in said tube wall proximate said interior.

A method of securing a sheet material to a roller tube comprising:
- forming a roller tube body from a tube wall defining an interior and an exterior, said roller tube body including a first end and a second end;
- forming a groove and flange in said tube wall proximate said exterior with the absence of protrusions in said interior of said tube wall;
- inserting a sheet material into said groove;
- and
- deforming said flange over said groove to fix said sheet material to said roller tube.

A roller tube comprising:
- a body having a tube wall defining an interior and an exterior, said body including a first end and a second end opposite said first end;
- and
- a surface feature formed in said tube wall proximate said exterior, said surface feature configured to receive an attachment insert for coupling sheet material to said tube wall, wherein;
- said surface feature includes at least one flange extending from a groove formed in said tube wall;
- said at least one flange is deformable and configured to substantially close over said groove to secure said attachment insert to said tube wall exterior;
- and
- said surface feature allows a generally circular profile to be maintained in said tube wall proximate said interior.
4 more elements
A roller tube comprising:
- a body having a tube wall defining an interior and an exterior, said body including a first end and a second end opposite said first end;
- and
- a surface feature formed in said tube wall proximate said exterior, said surface feature configured to receive an attachment insert for sheet material;
- wherein:
- said surface feature comprises a groove running longitudinally along the exterior of said body and adapted to slidably receive said attachment insert therein;
- the tube wall varies in thickness and has a relatively thick section to accommodate said groove being formed therein;
- and
- the exterior of said body is eccentric with respect to the interior of said body due to the varying thickness of the tube wall.
