Abstract
A sheet article, the sheet article including a substrate, a plurality of fasteners on at least a portion of one surface of the substrate, and a cover, at least partially covering the plurality of fasteners, wherein the cover at least partially protects the plurality of fasteners and prevents the plurality of fasteners from engaging other fasteners or pressing down and wherein the covered fasteners can be exposed or the cover can be removed if need.
Claims21
A tool for handling a sheet, comprising:
- a base;
- a connector coupled to a driving force;
- a housing unit in the base;
- a moving element, positioned at least partially within and coupled to the housing unit and coupled to the driving force;
- and
- a first plurality of fasteners disposed on at least a portion of a surface of the moving element to engage and interlock a second plurality of fasteners disposed on the sheet;
- wherein a change in position of the moving element disengages and unlocks the first plurality of fasteners from the second plurality of fasteners;
- wherein after disengagement and unlocking of the first plurality of fasteners from the second plurality of fasteners, the first plurality of fasteners remain disposed on the surface of the moving element, and the moving element remains coupled to the housing unit.
5 more elements
A sheet-handling tool to grab and release a sheet material, the tool comprising:
- a base having a bottom contact surface;
- at least one moving element coupled to the base, wherein the at least one moving element has a surface, and the moving element moves either rotatably or retractably relative to the base between a position A and a position B;
- a first plurality of fasteners disposed on only one of said bottom contact surface and a portion of said surface of the moving element;
- wherein when the tool is placed on the sheet material and when the moving element is in the position A, the first plurality of fasteners engage and interlock the sheet material;
- wherein when the moving element moves from the position A to the position B, a change in positions of the base and the moving element makes the first plurality of fasteners no longer available to engage and interlock the sheet material;
- and
- wherein after disengagement and unlocking of the first plurality of fasteners from the sheet material, the first plurality of fasteners remain disposed on one of said bottom contact surface and said portion of said surface of the moving element.

A tool to selectively grab and release a fiber sheet, the tool comprising:
- a base having a bottom contact surface;
- at least one moving element coupled to the base and moves from a position A to a position B, relative to the base, wherein the moving element has a surface;
- a first plurality of fasteners disposed either on the bottom contact surface or on a portion of the surface of the moving element, wherein the first plurality of fasteners engage and interlock with a second plurality of fasteners disposed on the fiber sheet;
- when the tool is placed on top of the fiber sheet and physically touches the fiber sheet, and when the moving element is in the position A, the first plurality of fasteners make physical contact with the second plurality of fasteners, thereby engaging, interlocking, and grabbing the fiber sheet;
- when the first plurality of fasteners and the second plurality of fasteners are engaged and interlocked, the moving element disengages the first plurality of fasteners from the second plurality of fasteners by moving to the position B, which causes said portion of the surface of the moving element and the bottom contact surface to misalign;
- and
- wherein after disengagement and unlocking of the first plurality of fasteners from the second plurality of fasteners, the first plurality of fasteners remain disposed either on the bottom contact surface or on said portion of the surface of the moving element.
