摘要： An optical fibre unit (10) comprises a sheath (12) and a plurality of optical fibre element (14) loosely housed in the sheath. The sheath is coated with particles of an adherence reducing substance and has a radial thickness that is not substantially greater than 0.3mm. The coating (16) of adherence reducing particles is applied as a liquid coating comprising a dispersion of the particles and heat is applied to evaporate the liquid content of the liquid coating to produce a dry coating of particles on the sheath.

摘要： The present invention relates to a self-supporting tyre (100) for motor vehicles which comprises sidewall reinforcing inserts (113A, 113B) with different stiffness. In particular, the sidewall reinforcing insert on the side of the tyre most stressed during driving is less rigid than the sidewall reinforcing insert on the less stressed side. The tyre of the invention exhibits a reduced rolling resistance and better comfort in normal driving and an unexpected increase in mileage in run-flat driving.

摘要： The present invention relates to compositions for elastomeric compounds for tyres, in particular for tyre treads, comprising particular reversible cross-linking agents, tyre components and tyres for vehicle wheels which comprise them. The present elastomeric compounds, due to their particular hysteretic behaviour, allow manufacturing tyres characterised by a lower rolling resistance during moderate driving and at the same time greater resistance to tearing and road grip during sports driving.

摘要： A method of managing a process for building tyres (2) for vehicle wheels between a steady-state operating condition and a drum change operating condition. During the steady state operating condition, it is provided to sequentially and cyclically move N drums (100) configured for a first size along a building path (30) comprising a first path (110), with N being an integer greater than or equal to 1. The movement along the first path (110) is carried out by moving, with a moving device (170), one of the N drums (100) configured for the first size at a time, coupled with a first pair of axially opposite support elements (101), said first pair of support elements (101) being coupled with the moving device (170) and being configured for said first size. During the drum change operating condition to a second size, it is provided to replace said first pair of support elements (101) with a second pair of support elements (201) configured for said second size. The invention also relates to a line for building tyres (2) for vehicle wheels operating according to a steady-state operating condition and a drum change operating condition.
