Abstract
Abstract A method for splicing together the ends of glass yarns, especially tire cords composed of fiberglass, that have been previously coated with a synthetic polymer latex to render them compatible with synthetic rubber, consisting of helically wrapping together the respective ends to be spliced with a wrapping material compatible with both the synthetic polymer latex and synthetic rubber, compressing and holding the yarns or cords to be spliced or joined. The wrapping material may be a heat stable substance, an elastomeric polymer, or a thermosensitive nylon or polyester fiber.

Claim 9
Independent Claim
69 words
A method of splicing fiberglass cord coated with resorcinolformaldehyde latex comprising the steps of: a. crossing the coated fiberglass cord ends, b. wrapping the crossed yarn ends at their point of intersection with nylon wrapping material of relatively fine denier with respect to the denier of the material being wrapped, c. overwrapping said yarn ends with said wrapping material, and d. heating said nylon wrapping to form a splice.
Claim 10
Dependent Claim
52 words
A yarn splice comprising: a. yarn ends of an inorganic yarn coated with a synthetic polymer latex arranged in overlapping side-by-side relationship, b. a wrapping material helically wound around and embedded in said coated yarn ends, said wrapping material compressing said yarn ends, and c. said splice exhibiting no free yarn ends.
Claim 11
Dependent Claim
53 words
A yarn splice comprising: a. yarn ends of an inorganic yarn coated with a synthetic polymer latex arranged in overlapping side-by-side relationship, b. a textile wrapping material helically wound around and embedded in said coated yarn ends, said wrapping material compressing said yarn ends, and c. said splice exhibiting no free yarn ends.
Claim 12
Dependent Claim
15 words

Claim 20
Dependent Claim
50 words
A yarn splice comprising: a. yarn ends of fiberglass coated with a synthetic polymer latex arranged in overlapping side-by-side relationship, b. a thermosensitive heat-shrinkable nylon wrapping material helically wound around and embedded in said coated fiberglass, said nylon compressing said yarn ends, c. said splice exhibiting no free yarn ends.
Claim 21
Independent Claim
154 words
A method for splicing two ends of an inorganic yarn, coated with synthetic polymer latex, comprising the steps of: a. crossing the yarn ends to be spliced, b. wrapping the crossed yarn ends at their point of intersection with a wrapping material of relatively fine denier with respect to the denier of the material being wrapped, while moving the crossed yarns in a first axial direction, c. cutting one free yarn end near the wrapped portion, d. moving the just wrapped portion in the opposite direction while continuing wrapping to cover the cut end, e. cutting the other free yarn end near the wrapped portion, f. moving the wrapped portion at least in the first mentioned axial direction while continuing wrapping to cover the other cut end, g. and removing the just formed splice from the wrapping area and breaking the tail of the wrapping material, h. heating said wrapped area of the yarn.
Claim 22
Dependent Claim
23 words
