The present invention provides methods for preparing the nut waste sheet composites from a nut waste component and one or more binders.

An extrusion apparatus intended for the manufacture of a coextruded profiled element P for tyres, produced from rubber compounds of various compositions, comprises a profiling device (30) arranged at the outlet of at least two flow channels (34, 35) for rubbery compounds of different composition. The said channels receive the compounds from positive-displacement contrarotating twin-screw extruders (10, 20), the screw flights interpenetrating and having conjugated profiles.

The invention relates to a rubber blend, to a sulfur-crosslinkable rubber mixture comprising the rubber blend and to a vehicle tire comprising such a rubber mixture. The rubber blend comprises at least one solution-polymerized diene polymer A of high molecular weight and at least one solution-polymerized polymer B of low molecular weight,
wherein at least one of polymers A and B has been functionalized at the chain end and/or along the polymer chain and/or at a coupling site with at least one group selected from epoxy groups, hydroxyl groups, carboxyl groups, silane sulfide groups, amino groups, siloxane groups, organosilicon groups, phthalocyanine groups and amino group-containing alkoxysilyl groups.

A method for stacking a ply (50) which is transferred from a rubber mixing system to a stacking system (100) comprises the steps of transferring the ply (50) to a stacking head (120) of the stacking system (100); passing the ply (50) to a motorized belt (110) of the stacking system (100), the motorized belt (110) being able to turn in both directions and being able to move in translation, and the motorized belt (110) being situated between the stacking head and a pallet (P) chosen from a pallet (P) with edges and a pallet (Q) without edges; and setting the motorized belt (110) into movement in translation so as to move along a path such that the motorized belt (110) receives the ply (50) from the stacking head (120) and makes a downstream end (50b) of the ply (50) to be stacked accessible in order to connect it to an upstream end (52a) of a ply (52) of a successive pallet and form a butt joint between the plies (50, 52).

A pad for preventing tire skidding and a manufacturing method thereof, and is to provide a pad for preventing tire skidding and a manufacturing method thereof configured by a friction member formed by mixing a raw material rubber containing butadiene rubber and a functional additive; an adhesive layer coated with an adhesive on one side of the friction member so that the friction member is able to be adhered to a vehicle tire; and a mesh net embedded in the friction member or a mesh net connected to a piezoelectric element. The pad is provided with an adhesive layer coated with an adhesive and can be easily attached and used onto a vehicle tire, and is made of a large amount of butadiene rubber to increase the friction force against the ground.

In the field of tire production, systems and methods utilize a feed belt (150) for directing a rubber mixture from an initial mixing installation (20) toward at least one of two mixing and cooling installations (100, 100′). It is possible to selectively carry out monopassage and multipassage rubber production sequences in a common rubber production facility. A tire is formed according to the methods described.

A main extruder and a side arm extruder are used in the extrusion of plastics with small amounts of additives or other small substances to be admixed. A minor portion of the plastic material is premixed with small quantity additive substances in a side arm extruder. The premixed material is discharged from the side arm extruder into the main extruder and there mixed with a major portion of feed material.

In kneading rotors, a twist angle of long wing constituting kneading wings is between 38 degrees and 53 degrees inclusive. The long wing includes, between the long wings and an inner surface of a casing, wing tops configured to form, along a wing longitudinal direction, a first tip clearance, and a second tip clearance narrower than the first tip clearance in width. A central angle of the long wing forming the second tip clearance is between 5 degrees and 10 degrees inclusive.

The invention relates to a sulfur-crosslinkable rubber mixture comprising a rubber blend composed of at least one solution-polymerized diene polymer A of high molecular weight and at least one solution-polymerized polymer B of low molecular weight, wherein at least one of polymers A and B has been functionalized at the chain end and/or along the polymer chain and/or at a coupling site with at least one group selected from epoxy groups, hydroxyl groups, carboxyl groups, silane sulfide groups, amino groups, siloxane groups, organosilicon groups, phthalocyanine groups and amino group-containing alkoxysilyl groups, 30 to 300 phr of at least one silica and 1 to 20 phf of at least one blocked and/or unblocked mercaptosilane as silane coupling agent.

The invention relates to a rubber blend, to a sulfur-crosslinkable rubber mixture comprising the rubber blend and to a vehicle tire comprising such a rubber mixture.

The rubber blend comprises at least one solution-polymerized diene polymer A of high molecular weight and at least one solution-polymerized polymer B of low molecular weight,
wherein at least one of polymers A and B has been functionalized at the chain end and/or along the polymer chain and/or at a coupling site with at least one group selected from epoxy groups, hydroxyl groups, carboxyl groups, silane sulfide groups, amino groups, siloxane groups, organosilicon groups, phthalocyanine groups and amino group-containing alkoxysilyl groups.
