Abstract
A sheet of material () formed for control bending along a bend line () while maintaining a continuous web of material () across the bend line (). The sheet has at least one groove () formed therein with a central groove portion () extending in the direction of and positioned proximate to a desired bend line (). The groove is formed with a continuous web of material () at a bottom of the groove () and has a configuration defining at least one bending strap () extending across the bending line () at the end of the groove with a centerline () of the bending strap () oriented obliquely across the bend line () so that a balancing of the forces during bending of the web along the central portion () of the grooves and bending of the oblique bending strap occur and control the location of bending of the sheet. A method of preparing a sheet of material () for bending while maintaining a continuous membrane () across the bend line () is also disclosed.
