Abstract
Abstract A mold for tacking an hexagonal bundle of glass fibers, such as those utilized in the fabrication of microchannel electron multiplier plates is disclosed. The mold includes a generally channel-shaped base member having longitudinally directed sides upstanding from a flat base. A plurality of longitudinally directed angle blocks are movable within the channel for defining, with the flat base surface, the flat sides of an hexagonal bundle of glass fibers. The blocks are adjustable to compensate for dimensional variations of the individual fibers such that the resultant tacked bundle has dimensions which are accurately controlled and in which the fibers are accurately positioned with the fibers tacked together without producing undue distortion of the individual fibers within the bundle.

Claim 1
Independent Claim
296 words
In a mold for tacking a bundle of glass fibers into a composite bundle of hexagonal cross section, a channel means having first and second transversly spaced longitudinally directed sides upstanding from a base portion, said base portion having a flat horizontal base face facing upwardly between said upstanding sides to define a first face of the hexagonal bundle, means within said channel and extEnding along said first upstanding side thereof for defining a flat second face of said hexagonal bundle in a plane inclined at an angle of 120* to said first horizontal base face, said second face facing generally towards said second side of said channel, first means disposed within said channel and extending along said second side thereof and having a third flat face in a plane inclined at an angle of 120* to said first horizontal base face for defining a third face of the hexagonal bundle, said third face facing generally toward said first side of said channel, means for transversely translating said first means in the horizontal direction, second and third means extending longitudinally of said channel means, along opposite sides thereof, each of said second and third means having fourth and fifth flat faces facing into said channel and each inclined at an angle of 120* to said first horizontal base face and being parallel with said aforementioned third and second faces, respectively, to define fourth and fifth faces of the hexagonal bundle, said second and third means being translatable in directions parallel to said aforementioned second and third faces, respectively, and fourth longitudinally directed means interposed between said second and third means and having a horizontal sixth face facing into said channel to define the sixth face of said hexagonal bundle, and said fourth means being vertically translatable.
Claim 2
Dependent Claim
296 words
In a mold for tacking a bundle of glass fibers into a composite bundle of hexagonal cross section, a channel means having first and second transversly spaced longitudinally directed sides upstanding from a base portion, said base portion having a flat horizontal base face facing upwardly between said upstanding sides to define a first face of the hexagonal bundle, means within said channel and extEnding along said first upstanding side thereof for defining a flat second face of said hexagonal bundle in a plane inclined at an angle of 120* to said first horizontal base face, said second face facing generally towards said second side of said channel, first means disposed within said channel and extending along said second side thereof and having a third flat face in a plane inclined at an angle of 120* to said first horizontal base face for defining a third face of the hexagonal bundle, said third face facing generally toward said first side of said channel, means for transversely translating said first means in the horizontal direction, second and third means extending longitudinally of said channel means, along opposite sides thereof, each of said second and third means having fourth and fifth flat faces facing into said channel and each inclined at an angle of 120* to said first horizontal base face and being parallel with said aforementioned third and second faces, respectively, to define fourth and fifth faces of the hexagonal bundle, said second and third means being translatable in directions parallel to said aforementioned second and third faces, respectively, and fourth longitudinally directed means interposed between said second and third means and having a horizontal sixth face facing into said channel to define the sixth face of said hexagonal bundle, and said fourth means being vertically translatable.
Claim 3
Dependent Claim
26 words

The apparatus of claim 1 wherein said means for translating said first means comprises a pair of adjusting screws passing through said second side of said channel means.
Claim 5
Dependent Claim
25 words
The apparatus of claim 1 wherein said second and third means include respective faces disposed in slideable engagement with said second and third flat faces.
Claim 6
Dependent Claim
19 words
The apparatus of claim 1 wherein said channel, first, second, third and fourth means are all made of carbon.
Claim 7
Dependent Claim
14 words
The apparatus of claim 1 wherein said channel means comprises a rigid unitary member.
