Claim 1
Independent Claim
112 words
A filiform and flexible primary textile strand which is capable of being wound for storing with adjacent turns in direct contact one relative to the other before being used and which is capable of being woven, wherein said textile strand comprises at least one assembly of continuous chemical individual filaments covered by a thread of continuous chemical filaments around said assembly of individual filaments in the form of a helix, said strand having a substantially circular cross-section, said thread of continuous filaments forming an outer surface with protuberances and hollows, said assembly of individual filaments being preimpregnated with a nonpolymerized resin and said thread of continuous filaments being not impregnated with resin.
Claim 2
Dependent Claim
112 words
A filiform and flexible primary textile strand which is capable of being wound for storing with adjacent turns in direct contact one relative to the other before being used and which is capable of being woven, wherein said textile strand comprises at least one assembly of continuous chemical individual filaments covered by a thread of continuous chemical filaments around said assembly of individual filaments in the form of a helix, said strand having a substantially circular cross-section, said thread of continuous filaments forming an outer surface with protuberances and hollows, said assembly of individual filaments being preimpregnated with a nonpolymerized resin and said thread of continuous filaments being not impregnated with resin.
