Abstract
Abstract A base supports a workpiece form-holding means in either a stationary or rotatable manner. A cross-slide and corresponding fiber creel assembly which is affixed to, and depends from, the cross-slide assembly is carried with respect to the workpiece form-holding means by a hanging carriage carried on an overhead support beam. A fiber payout eye is carried on the cross-slide assembly for guiding fiber from the fiber creel assembly to the workpiece form as the carriage and cross-slide are moving.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
145 words
In a fiber placement machine, having: a base; and a workpiece form-holding means on said base for supporting a workpiece form along a substantially horizontal axis: an improved fiber delivery assembly, comprising: a pair of support stanchions affixed to said base; an elongate horizontal support beam; beam ways parallel to said horizontal axis; opposite beam ends supported on said stanchions; a carriage mounted to said beam ways and depending from said beam; carriage ways normal to said horizontal axis; a cross slide assembly mounted to said carriage ways; means for moving said carriage on said beam ways between said stanchions; means for moving said cross slide on said carriage ways; a fiber creel assembly affixed to, and depending from, said cross slide assembly; and fiber payout means, mounted on said cross slide assembly, for guiding fiber from said fiber creel assembly to said workpiece form.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
48 words
The fiber placement machine of claim 1, wherein said fiber payout means includes: a tooling plate; a fiber payout eye mounted to said tooling plate; and an articulatable robotic wrist means for moving said tooling plate in a direction normal to said beam ways and said carriage ways.
Claim 4
Dependent Claim
24 words
The fiber placement machine of claim 1, wherein said workpiece form-holding means includes: means for rotatably driving said workpiece form about said horizontal axis.
Claim 5
Dependent Claim
24 words
The fiber placement machine of claim 2, wherein said workpiece form-holding means includes: means for rotatably driving said workpiece form about said horizontal axis.
Claim 6
Dependent Claim
47 words
The fiber placement machine of claim 1, wherein said cross slide assembly includes: a first end proximal to said workpiece form-holding means, supporting said fiber payout means; a second end distal to said workpiece form-holding means; and a wrist means drive mechanism supported by said second end.
Claim 7
Dependent Claim
47 words
The fiber placement machine of claim 2, wherein said cross slide assembly includes: a first end proximal to said workpiece form-holding means, supporting said fiber payout means; a second end distal to said workpiece form-holding means; and a wrist means drive mechanism supported by said second end.
Claim 8
Dependent Claim
68 words
The fiber placement machine of claim 1, wherein said cross slide assembly includes: a subslice mounted on said carriage ways; a pivot housing rotatably journalled with said subslide for movement about a horizontal axis; means for securing said payout means to said pivot housing; and actuator means for pivoting said pivot housing with respect to said subslide and providing a vertical component of movement to said payout means.
