摘要:
A metallic cable adapted to be used to advantage for reinforcing various types of elastomeric articles such as belts and motor vehicle tires has a core formed from two or more metallic filaments wound together into a helical shape without twisting one filament about the other whereby each core filament lies in line contact with at least one other core filament, the line of contact being parallel to the direction of the filament and a helically wound wrapping filament is disposed about the core filaments. The wrapping filament is helically wound at the same lay and hand as the core filaments and is positioned on the inside of the helix formed by the core filaments.
摘要:
A reinforcement system for pneumatic tires featuring combination cords of individually varying extensibility composed of elements of extensible character and, combined therewith, elements of relatively inextensible character; the combination cord of greatest extensibility being preselectively located in the region of the tire subjected to the greatest deflection whereby the stress incurred during average environmental usage or of a particular impact is not transferred to the elements of relatively inextensible character until the deflection has reached a value preselectively determined. The combination cords include an organic and a somewhat greater length of substantially inextensible material, e.g., glass, so combined therewith as to yield a unit length, and are tailor-made to exhibit a particular degree of elongation depending upon the particular combination of variable lengths and the selection of organic elements to be combined with the glass.
摘要:
Tires which are substantially non-flatspotting are reinforced with nylon cord treated with aliphatic hydroxylated plasticizer, which cords are stretched while heating, and the tires are thereby made substantially non-flatspotting.

摘要:
A fiber especially suitable for reinforcing bitumen-containing materials which comprises a fiber of polyethylene terephthalate having a tenacity of at least about 7.5 grams per denier, an elongation at break of at least about 9 percent, an elongation of not more than about 5 percent under a load of 5 grams per denier and a shrinkage of less than 4 percent when kept under a tension of 0.05 grams per denier for 4 minutes at about 160*C. Also a process for producing this fiber and a bitumen-containing structure reinforced therewith are disclosed.
摘要:
Organic and glass filaments, yarns and/or strands are combined, with the organic component as the core and the glass component as the overwrap, followed by a treatment which causes the organic to shrink, causing spaced portions of the glass component to move or to tend to move radially outwardly with respect to the longitudinal axis of the combined structure and whereby, when the combined structure is in an elastomeric matrix, the region of the matrix contiguous to the organic component is in a state of compression while the glass component exhibits greater anchoring potential with the elastomeric matrix.
