Positioning a workpiece on a sticky gasket
View Patent ↗Applicants provide a step in the assembly of a moveable workpiece to a static base, the base bearing a sticky gasket and in which a release agent is sprayed on the sticky upper surface of the sticky gasket, which release agent will render the sticky surface temporarily unsticky.
1. A method for positioning a removable workpiece on a base with a gasket between the workpiece and the base, the gasket having a skinned side covering a sticky body and an uncovered sticky side, the method comprising the steps of:
providing the gasket, a liquid tack release agent, and a release agent applicator;
applying the sticky side of the gasket to the base;
removing the skin from a top surface of the gasket;
spraying the top surface of the gasket with the release agent;
manually laying the workpiece on the wetted top surface of the gasket;
aligning the workpiece to a predetermined alignment with the base; and
allowing the release agent to dry.
2. The method of claim 1 , wherein the workpiece and the base each have a multiplicity of fastener holes therein and wherein the aligning step includes the step of aligning the holes of the workpiece and the fasteners.
3. The method of claim 2 , wherein the workpiece is an aircraft floor panel and the base is an aircraft stringer.
4. The method of claim 2 , wherein the gasket has a skeleton and further including, following the removing step, the step of creating holes in the skeleton at any points where the gasket overlaps the holes.
5. The method of claim 2 , wherein the aligning step further includes the step of placing a member in a pair of aligned holes and moving the workpiece about the member to align the remaining holes of the workpiece with the holes of the stringer.
6. The method of claim 3 , wherein the gasket is a polyurethane gasket tape and the applying step includes applying the gasket tape sticky side down on the stringer.
7. The method of claim 6 , wherein the liquid tack release agent is an alcohol.
8. The method of claim 6 , wherein the liquid tack release agent is a solution of a surfactant and water.
9. A method for positioning a removable workpiece on a base with a gasket between the workpiece and the base, the gasket having a skinned side covering a sticky body and an uncovered sticky side, the method comprising the steps of:
providing the gasket, a liquid tack release agent, and a release agent applicator;
applying the sticky side of the gasket to the base;
removing the skin from a top surface of the gasket;
spraying the top surface of the gasket with the release agent;
manually laying the workpiece on the wetted top surface of the gasket;
aligning the workpiece to a predetermined alignment with the base; and
allowing the release agent to dry;
wherein the workpiece and the base each have a multiplicity of fastener holes therein and wherein the aligning step includes the step of aligning the holes of the workpiece and the fasteners;
wherein the workpiece is an aircraft floor panel and the base is an aircraft stringer;
wherein the gasket is a polyurethane gasket tape and the applying step includes applying the gasket tape sticky side down on the stringer;
wherein the liquid tack release agent is an alcohol;
wherein the gasket has a skeleton and further including, following the removing step, the step of creating holes in the skeleton at any points where the gasket overlaps the holes; and
wherein the aligning step further includes the step of placing a member in a pair of aligned holes and moving the workpiece about the member to align the remaining holes of the workpiece with the holes of the stringer.
