Tire profile for a pneumatic tire (10) of an automobile comprising a tread portion comprising at least one sipe (20), the sipe (20) comprising an extension in a width direction (22) and a depth in radial direction (24), wherein the sipe (20) comprises a first portion (36) and a second portion (38) arranged radially inward to the first portion (36), wherein the first portion (36) an d the second portion (38) are inclined to each other along a connecting line by an angle gammal, wherein the angle yl changes along width direction (22) continuously. Due to the continuous change of the angle gammal between the first portion (36) and the second portion (38) a good grip and a high efficiency at low as well as at high friction surfaces can be provided so that a tire (10) with a good grip to an underground is possible.


The invention related to a method of manufacturing an elastomeric product, e.g. rubber products, with a low hysteresis. The method comprises at least the steps of providing an elastomeric material composition which comprises an elastomeric material, sulfur and a peroxide and vulcanizing the blend at a selected reaction temperature that is higher than the temperature at which cross-links are formed in the composition, and that is between the temperature at which the half-life time of the peroxide is 1 hour and 50 C. above the temperature at which the half-life time of the peroxide is 1 hour. The composition shows a low level of hysteresis in combination with good (tear) strength, in particular at low temperatures.

A vehicle front spoiler comprises a flexible airflow guiding element provided in a region of a front part of the vehicle and extending in a transverse direction Y of the vehicle, and an actuating member, configured to move the airflow guiding element relative to said part of the vehicle between an extended operative position and a retracted inoperative position in which the airflow guiding element is folded rearwards to behind said vehicle part. The airflow guiding element is made of a rubber composition comprising an anisotropic textile structure of reinforcement cord having an elongation at break in the Y-direction of from 5% to 50%, and an elongation at break in the Z-direction lower than the elongation at break in the Y-direction, and is readily moved between the operative and the inoperative position with relatively low hysteresis losses.


The invention relates to a method for manufacturing a molded article from a first rubber polymer, which molded article comprises an insert from a second rubber polymer. The method comprises the steps of (A) providing an at least partially vulcanized article from the first rubber polymer, the article having a recess that extends in a depth direction and in transverse directions perpendicular to the depth direction, for accommodating the insert; (B) providing an at least partially vulcanized insert from the second rubber polymer, the insert having a shape such that it can be accommodated in the recess; (C) arranging an unvulcanized object from a third rubber polymer in the recess to partly fill the recess; (C) arranging the at least partly vulcanized insert in the recess to obtain an assembly; and (D) vulcanizing the assembly under pressure. The method yields a molded article having an optically sharp interface between the first rubber polymer and the insert.

Natural rubber (NR) is an essential renewable material for more than 40,000 products essential to building (adhesives, sealants), medicine (gloves, tubing), and transportation (matting, tyres) industries. In many applications NR cannot be replaced by synthetic rubbers. At the moment NR is harvested exclusively from the rubber tree (Hevea brasiliensis) of which 90% is grown in South East Asia. Worldwide NR consumption is forecasted to increase significantly. At the moment the EU is completely dependent on imports of NR. The successful EU-PEARLS project, which finished in 2012, demonstrated the viability of a new NR producing concept: Russian dandelion (Taraxacum koksaghyz , abbreviated TKS). Not demonstrated in the EU-PEARLS project, but of equal importance in the construction of the TKS business case, is the fact that TKS is also a promising new crop for biomass derived building blocks for the chemical industry via the production of inulin. The strategic objective of EU-DRIVE is to demonstrate the economic potential of a European production chain for natural rubber and inulin as building block for green chemicals, using TKS as a dual purpose production platform. The main deliverables of DIRVE4EU are: (1) plant genotypes with high root biomass, high rubber and inulin yield, (2) seed batches for agronomic tests and large scale demo field trials, (3) optimized cultivation and harvest methods for TKS, (4) ecological analysis of the gene flow between TKS and wild dandelions, (5) scaled-up and optimised extraction and refinery protocol for TKS NR and inulin, (6) testing and application of TKS NR and inulin in end product uses, (7) demonstration of the economic viability of the TKS production chain for NR and inulin. To reach the objective a strong consortium of 8 industrial partners and 5 research organisations from 7 EU countries and Kazakhstan is constructed with a very broad background from bioscience to the rubber industry.

The invention relates to a method for providing a tire with an informative label. The method comprises supporting a tire, supplying a banding material to the tire and wrapping it in a loop around a part of the tire, holding the banding material at the neck of said loop, and connecting opposed areas of the banding material at said neck to form a label wrap. The invention further relates to an apparatus for carrying out the method and to a tire provided with the label. The informative label is easily removed by a mechanic and shows an improved processability and printability. The informative label further does not leave any adhesive or other residuals on a tire.
