Abstract
Abstract Static electricity apparatus is provided including a device in the form of a wand coupled to a source of unidirectional potential for temporarily mounting a layer being worked onto a vertical or horizontal layer of high dielectric material. The layer being worked on is between a grounded substrate and the dielectric material. When the wand is moved over the layers, the layers are pinned together by static electricity. The substrate is of ground potential and provides a reference or basis for the electrical charge taken by the dielectric material.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
102 words
A static electricity pinning method for closely adhering together a film having photosensitive emulsion thereon and an image bearing sheet for exposure to a light source without ''''undercutting'''' comprising: superimposing a said film, a said sheet and a layer of high dielectric strength material onto a grounded conductive substrate, with said film and said sheet between said layer and said substrate, and at least one of said substrate and layer being light transmitting, and electrostatically pinning together said superimposed layers by moving a wand having ionizing points connected to a source of direct current over and in juxtaposition to said superimposed layers.
Claim 2
Dependent Claim
102 words

Claim 3
Dependent Claim
14 words
The method of claim 1, said layer of high dielectric strength material being transparent.
Claim 4
Dependent Claim
11 words
The method of claim 1, said sheet being adjacent said substrate.
