Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
99 words
A method of processing spliced filamentary materials which comprises placing portions of filamentary materials in splicing relationship, applying a hardenable material to the segments to maintain the segments in spliced relationship, hardening said material to form a friable bond between the segments and friable bond possessing sufficient strength to enable handling of the filamentary materials and to avoid breakage of the bond at this point of processing and processing the filamentary material to break the friable bond by applying pressure to the bond, said friable bond being of such a nature as to disintegrate at this point of processing.
Claim 2
Independent Claim
99 words
A method of processing spliced filamentary materials which comprises placing portions of filamentary materials in splicing relationship, applying a hardenable material to the segments to maintain the segments in spliced relationship, hardening said material to form a friable bond between the segments and friable bond possessing sufficient strength to enable handling of the filamentary materials and to avoid breakage of the bond at this point of processing and processing the filamentary material to break the friable bond by applying pressure to the bond, said friable bond being of such a nature as to disintegrate at this point of processing.
Claim 3
Dependent Claim
23 words
The method of claim 1 in which said bond is soluble in a material comprising the sheet molding compound or bulk molding compound.
Claim 4
Dependent Claim
16 words
The method of claim 2 wherein the sheet molding compound or bulk molding compound includes styrene.
Claim 5
Dependent Claim
23 words
A process according to claim 1 wherein the friable bond has a tensile strength ranging from about 40 Newtons to about 130 Newtons.
Claim 6
Independent Claim
114 words
A method of processing spliced filamentary materials which comprises placing portions of filamentary materials in splicing relationship, applying a hardenable material to the segments to maintain the segments in spliced relationship, hardening said material to form a friable bond between the segments said friable bond possessing sufficient strength to enable handling of the filamentary materials and to avoid breakage of the bond at this point of processing and processing the filamentary material to break the friable bond said friable bond being of such a nature as to disintegrate at this point of processing wherein the spliced filamentary material is incorporated in sheet molding or bulk molding compound which is processed to break said bond.
Claim 7
Independent Claim
114 words
A method of processing spliced filamentary materials which comprises placing portions of filamentary materials in splicing relationship, applying a hardenable material to the segments to maintain the segments in spliced relationship, hardening said material to form a friable bond between the segments said friable bond possessing sufficient strength to enable handling of the filamentary materials and to avoid breakage of the bond at this point of processing and processing the filamentary material to break the friable bond said friable bond being of such a nature as to disintegrate at this point of processing wherein the spliced filamentary material is incorporated in sheet molding or bulk molding compound which is processed to break said bond.
