HOOPING REINFORCEMENT FOR A TIRE OF A HEAVY DUTY CIVIL ENGINEERING VEHICLE
20200062037 · 2020-02-27 ·

The manufacturing cost of a hoop reinforcement of a tire for a heavy vehicle of construction plant type is reduced. The crown reinforcement (3) of the tire (1), radially on the inside of a tread (2), comprises a protective reinforcement (6), a working reinforcement (5) and a hoop reinforcement (7). The hoop reinforcement (7) is made up of at least two hooping layers (71, 72), each hooping layer (71, 72) comprising metallic reinforcers that are coated in an elastomeric coating material and form an angle at most equal to 2.5 with the circumferential direction (XX). Each hooping layer (71, 72) is formed by a circumferential winding in a ring, in the circumferential direction (XX), of at least one portion of a ply of metallic reinforcers (81, 82), extending from an initial end (811, 821) to a final end (812, 822), such that the hooping layer (71, 72) comprises at least one discontinuity (91, 92).

REINFORCING PLY FOR ARTICLES MADE OF AN ELASTOMERIC MATERIAL, PREFERABLY FOR PNEUMATIC VEHICLE TYRES, AND PNEUMATIC VEHICLE TYRES

The invention relates to a rubberized reinforcing ply for articles made of elastomeric material, preferably for pneumatic vehicle tires, where the reinforcing ply has a multitude of strength members which are arranged in parallel and spaced apart, where each strength member consists of at least one twisted multifilament yarn composed of polyethylene terephthalate (PET), where the multifilament yarn has a yarn count (linear density) of 50 to 1100 dtex and a linear density-based ultimate tensile strength of 70 cN/tex in accordance with ASTM D885-16, and where the rubberized material has a thickness D. The invention further relates to a pneumatic vehicle tire comprising this reinforcing ply.

The multifilament yarn has an elongation at break of 10% to 20% in accordance with ASTM D885-16, a crystallinity determined via DSC of 55% to 65% and a birefringence n with 0.21n0.25.

20190039415 · 2019-02-07 ·

An elastomeric article can include an elastomeric body that is at least partially formed from an elastomeric material. The elastomeric body can include a first surface portion and a second surface portion facing opposite the first surface portion. A first plurality of reinforcing elements can be embedded within the elastomeric body between the first and second surface portions. The first plurality of reinforcing elements can have a first end and a second end opposite the first end with the first plurality of reinforcing elements having a non-linear pattern formed therealong between the first and second ends thereof. As examples, the elastomeric article can at least partially form one of pneumatic or non-pneumatic tire, a flexible spring member of a gas spring assembly and/or a turnup bladder dimensioned for securement on an associated tire building machine. Methods of manufacturing an elastomeric articles are also included.
