A stabilizer adhesive bearing for a vehicle stabilizer may comprise an annular sleeve having a resilient inner contour for coaxial arrangement on the vehicle stabilizer. The resilient inner contour of the annular sleeve may comprise on a side facing the vehicle stabilizer a three-dimensionally structured surface with an adhesive receiving volume. The three-dimensionally structured surface has a maximum roughness depth (R.sub.max) greater than 45 μm and a core roughness depth (R.sub.K) of at least 65% relative to the maximum roughness depth (R.sub.max) of the three-dimensionally structured surface. The maximum roughness depth (R.sub.max) is a total of the reduced tip height (R.sub.pk), the core roughness depth (R.sub.K), and the reduced groove depth (R.sub.vk). Further, the reduced tip height (R.sub.pk), the reduced groove depth (R.sub.vk), and the core roughness depth (R.sub.K) may be determined in accordance with EN ISO 13565-2: December 1997.

An extrusion system (10) is provided that has first and second extruders (12,14) with first and second extrusion barrels (50,52). First and second extruded components (24,26) are transferred through the barrels (50,52) to a die (22) to coextrude tire tread (20) from the first and second extruded components (24,26). A horizontal plane (70) is located above ground in a vertical direction (40) and extends through both the first extrusion barrel (50) and the second extrusion barrel (52).

Disclosed is a novel 3D-printer system for printing elastically deformable rubber parts such as rubber seals where the uncured rubber source material is partially cured before printing each rubber layer of the rubber part. Furthermore, disclosed is a novel 3D printing method for 3D-printing an elastically deformable rubber body using the 3D-printer system.

A porous structural body 1 made of flexible resin or rubber, the porous structural body includes a skeleton part 2 throughout its entirety. The skeleton part includes a plurality of bone parts 2B and a plurality of coupling parts 2J coupling end parts of the plurality of respective bone parts with each other. The skeleton part has a plurality of annular parts 211 each constituted of the plurality of bone parts and the plurality of coupling parts into an annular shape. Each annular part zones a virtual surface V1 by its inner peripheral side edge part 2111. At least a part of each of one or a plurality of the virtual surfaces is covered with one or a plurality of partially connected films 31. Each of the one or plurality of partially connected films is connected to only a part of the annular part in a peripheral direction.

A conveyance unit mounted to a machine for initial processing of natural raw rubber into aged rubber product, includes: a discharge delivery belt connected with the machine to receive the aged rubber product; a vibration delivery device connected to the discharge delivery belt to selectively delivery the aged rubber product from the discharge delivery belt; a drying and cooling device, comprising an elongated channel body and a circulation system mounted therein, wherein the rubber product is entered from one end of the elongated channel body while being dewatered and left from the other end of the elongated channel body, wherein the circulation system is operated to provide wind inside the elongated channel body for drying and cooling the rubber product; and a cutting device connected to the elongated channel body of the drying and cooling device to cut the dried rubber product into aged product.

A polymer latex including a polymer and at least one polysaccharide selected from the group consisting of tamarind gum, xanthan gum, cationized xanthan gum, gellan gum, guar gum and cationized guar gum.

A seal for a vacuum lifter and method of manufacture wherein the seal has a continuous unbroken outer fluid resistant skin of elastomer which forms a boundary around a homogeneous cellular structure with no interior seams or joints.

The method for the coextrusion of a complex profiled element made up of the assembly of profiled elements formed from distinct rubber compounds. A coextrusion machine comprises upstream and downstream extruders which deliver into an extrusion cavity. A first profiled element, formed of the first rubber compound, is created. The first profiled element comprises at least a first profiled-element portion which is intended to form a longitudinal insert, a base of which is in continuity of material with the first profiled element. A complex profiled element formed of the first and second rubber compounds is created. The insert is circulated between walls of a channel extend in a longitudinal direction between the upstream profiling blade and the downstream profiling blade and together form a concave surface open towards the inside of the extrusion cavity in such a way that the bringing-together of the lateral walls of the insert with the second compound takes place only in the downstream gap.

A method for manufacturing an object having a polymer part, including inserting a core through a movable element via a hole passing through the movable element, inserting the polymer part in a mould, inside which the movable element is arranged, so that the polymer part is in contact with the movable element on a first side of the movable element, displacing the movable element in the mould by exerting a force, originating from the polymer part, on the movable element in such a way that the movable element slides along the core, the movable element constraining, at an entrance of the hole on the first side, at each instant and as the movable element is displaced, the position of the portion of the core in the course of being covered with polymer at this instant.
