BELT THAT IS CONTINUOUSLY CLOSED IN THE LONGITUDINAL DIRECTION, IN PARTICULAR ROUND BALER BELT
A belt, such as a round baler belt, includes an internal region, an external region, a core region arranged between the internal region and the external region, and at least one peripheral region arranged transversely to longitudinal direction of the round baler belt. The peripheral region is arranged at least partially between the internal region and the external region, and the belt is continuously closed in the longitudinal direction. The peripheral region may be arranged entirely between the internal region and the external region. In some cases, at least one peripheral region is two peripheral regions located opposite one another transversely to the longitudinal direction. Furthermore, the core region may be continuously wound, and even formed of reinforcing fabric. In some aspects, the internal region and/or the external region and/or a peripheral region and/or both peripheral regions contain an elastomeric material.
Drive belts including foamed undercord layers and methods of manufacturing the same
A drive belt includes a foamed undercord layer having void spaces located throughout the foamed undercord layer. The void spaces extend from a backing layer of the undercord layer to an exterior surface of the backing layer, and may include some void spaces at the exterior surface that are open to the external environment. The foamed undercord layer may exhibit a 20% reduction in specific gravity as compared to an unfoamed version of the undercord layer. The manufacturing process for making the foamed undercord layer can include incorporating foaming agent in the undercord layer such that the undercord layer both foams and cures when heat and pressure are applied to the undercord layer. The foamed drive belt incorporating the foamed undercord layer may exhibit reduced bending stiffness and improved energy efficiency.
Web harness waist pad belts
A web harness belt includes multiple layers. A first elastomer layer portion and a second elastomer portion each connected to a ballistic material layer of the multiple layers. The first elastomer layer portion and the second elastomer layer portion each including multiple belt configuration slots.
Drive belts including foamed undercord layers and methods of manufacturing the same
A drive belt includes an undercord layer having a first region proximate a backing layer surface of the undercord layer and a second region proximate the exterior surface of the undercord layer, the first region being foamed and the second region either being foamed to a lesser extent than the first region or not being foamed. The drive belt further includes a cover layer formed over the exterior surface of the undercord layer. Alternatively, the drive belt may be foamed throughout the undercord layer thickness, with a cover layer formed on the exterior surface of the undercord layer. The manufacturing process for making the foamed undercord layer can include incorporating a first quantity of foaming agent in a first sheet of undercord layer material and either a second quantity of foaming agent in a second sheet of undercord layer material, the second quantity being less than the first quantity, or including no foaming agent in the second sheet. The first sheet and second sheet are disposed in a mold, to which heat and pressure is applied to cure the sheets and foam the first sheet and the second sheet when the second sheet includes foaming agent. The mold includes an exterior portion that forms ridges in the exterior surface of the undercord layer and a cover layer disposed on the exterior surface of the undercord layer. The drive belt incorporating the undercord layer having a foamed first region may exhibit reduced bending stiffness and improved energy efficiency.
Endless belt, belt unit, and image forming apparatus
An endless belt includes a base material layer, the base material layer containing a polymer material and conductive particles, wherein in a section of the base material layer in a thickness direction, the conductive particles have an area ratio of 9.0% or more and 14.5% or less, an average value of areas of Delaunay triangles taking centers of gravity of the conductive particles as vertices is 0.10 m.sup.2 or more and 0.90 m.sup.2 or less, and a standard deviation of the areas is 0.010 m.sup.2 or more and 0.080 m.sup.2 or less.
Toothed belt and manufacturing method therefor
The present invention relates to a toothed belt, including: a back portion including a tension member; a plurality of tooth portions; a back rubber layer; and a first rubber layer and a second rubber layer that are formed on a belt inner circumferential side with respect to the tension member, in which an elastic modulus of the first rubber layer is larger than that of the second rubber layer, the first rubber layer includes a first crosslinked rubber composition including a first rubber component and a first short fiber, a proportion of the first short fiber is 5 parts by mass to 60 parts by mass with respect to 100 parts by mass of the first rubber component, the first short fiber is oriented in a belt longitudinal direction along a contour of the tooth portion.
PAPER MACHINE CLOTHING
A paper machine clothing, such as a press felt for a machine for producing or processing a pulp web, has a base structure. The base structure has a first woven-fabric layer and a second woven-fabric layer which are arranged one above the other and each having threads in the machine direction (MD) and threads in the cross-machine direction (CD). Both the first woven-fabric layer and the second woven-fabric layer include threads which are in the form of monofilaments and threads that are in the form of twisted threads.
Belt or fabric including polymeric layer for papermaking machine
A fabric or belt for a papermaking machine including a first layer that defines a web contacting surface and a second layer that supports the first layer. The first layer is made of extruded polymer and includes a plurality of first elements aligned in a first direction, a plurality of second elements aligned in a second direction and extending over the plurality of first elements, and a plurality of open portions defined by the plurality of first and second elements. The second layer is made of woven or nonwoven fabric. The first layer is bonded to the second layer so that the first layer extends only partially through the second layer and an interface formed between the first and second layers includes bonded and unbonded portions and airflow channels that extend in a plane parallel to the first and second layers.
Unidirectional laid nonwoven and use thereof
For the production of components made of fiber-reinforced composites, in particular for the production of rotor blade belts, a unidirectional non-crimp fabric made of glass fiber rovings is provided, the non-crimp fabric having a first stabilizing layer on the underside thereof and a second stabilizing layer on the upper side thereof, which layers are sewn together by pillar stitching.
