Abstract
Abstract Apparatus is provided for molding a resin bonded glass fiber article. The apparatus includes a plurality of means for supplying separate bundles of glass fibers in cooperation with a plurality of feed eyes one of which is associated with each of the glass fiber supply means. Drive means displace the feed eyes along paths that are oppositely oblique to each other in order to position the glass fiber bundles within mold means that have recesses positioned adjacent the paths of the feed eyes.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
161 words
Apparatus for molding a resin bonded glass fiber article comprising: a. a plurality of means for supplying glass fibers; b. a plurality of feed-eyes each one of which is arranged to carry glass fibers from said means for supplying glass fibers; c. drive means adapted to move said feed-eyes along paths that are oblique to each other; and d. mold means positioned adjacent to the paths of said feed-eyes for receiving the glass fibers carried thereby, said mold means being comprised of an upper and lower member each of which has a plurality of substantially U-shaped grooves transversely intersecting each other whereby said grooves are combined to form the mold cavity, said grooves in one of said mold members having a marginal lip, said grooves in said other mold member having a marginal recess for receiving said lip, said lip and said recess being slightly spaced from each other during the molding operation whereby the resulting flash has a minimum thickness.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
24 words
The apparatus in accordance with claim 1 wherein, in combination, said grooves in said upper and lower members are substantially circular in cross section.
Claim 4
Dependent Claim
46 words
The apparatus in accordance with claim 1 further comprises: a. a first carriage movable in a first direction; b. a second carriage movable in a second direction that is transverse to said first direction; and c. said feed eyes being integral with one of said carriages.
Claim 5
Dependent Claim
36 words
The apparatus in accordance with claim 1 wherein the glass fibers carried by said feed eyes are deposited along intersecting paths that define the periphery of openings, there being twice as many feed eyes as openings.
Claim 6
Dependent Claim
44 words
The apparatus in accordance with claim 1 wherein the glass fibers carried by said feed eyes are deposited along intersecting paths that define the periphery of openings, there being twice as many feed eyes plus one as openings whereby the finished article includes selvage.
