The present invention relates to a manufacturing method for a rubber band, comprising preparing a production raw material: mixing and stirring by weight percent 50%-80% vinyl-terminated polydimethylmethylvinylsiloxane, 19%-40% silica and 1%-10% hydroxy-terminated polydimethylsiloxane into a paste ready for use; feeding the aforementioned production raw material into forming molds to produce rough rubber bands; soaking the rough rubber bands in a surface treatment solution for a certain time period, wherein the surface treatment solution comprises by weight percent 40%-50% methyl vinyl silicone rubber, 30%-35% deodorized kerosene, 7%-10% oxygen-containing silicon oil and 10%-20% silicon powder; taking the soaked rough rubber bands out of the solution after soaking and baking them at a high temperature of 200-250° C. A rubber band made according to the above-described method has good elasticity, a non-slip property, no cracks after stretching, is not easy to be broken, durable, non-toxic, environmentally friendly and nondeformable for multiple times of use.

Embodiments of the invention are used to provide ways of tire tread molding and retreading with a double tread rubber body having a unitary structure that comprises two treads in order to remove the need for buffing an oxide layer typically associated with tread molding and curing. Embodiments of the double tread molding and retreading methods also remove the need for cementing the cured tread to prevent future oxidation buildup. Once the double tread is cured and cooled, it is cut along the centerline with a double tread separation apparatus to expose a soft non-oxidized inner rubber. The cutting is much less energy intensive when compared to buffing with an expendable wire brush. There is no risk of spots of oxidized rubber being missed as is the case with buffing. There is little or no dust created.

A method for fabricating a drive belt includes: a cylindrical rubber formation step of forming a cylindrical rubber by roundly joining an uncrosslinked rubber sheet (31); and a mold covering step of covering a cylindrical mold with the cylindrical rubber formed in the cylindrical rubber formation step. A mark hot-transfer sheet (35) is adhered by hot pressing to the juncture of the cylindrical rubber to cover the juncture on the inside of the cylindrical rubber.
摘要:
Layers of materials are laminated together preserving potential spaces that can transmit pressure generated by the use of gases or fluids. Alternatively, pre-manufactured pressure conduits of suitable dimensions and geometries are integrated between the layers. Transmission of pressure to such conduits results in expansion of a compacted device to a predetermined shape. Maintenance and/or variation of said pressure results in preservation of said shape, fine static control of surface geometries and even remote control of precise movements. Osmotic Pressure is not required to achieve Turgor type control.

摘要:
A multi-layered belt, in particular a continuous running and/or transport and/or processing belt, includes a traction layer and a functional layer that contains a gel. To reduce the stress placed on the transported goods, in particular persons, the gel is an unplasticized gel and the functional layer consist of a coating containing the interspersed gel. In addition, to a method for producing a belt of this type is provided, in which the gel is poured in a continuous method onto the traction layer and a mixer and delivery unit is guided back and forth in a reversible manner perpendicular to the displacement direction of the traction layer in such a way that a gel layer with a uniform thickness is applied to the traction layer. Furthermore, the use of said belt as a running belt for persons, in particular as a running belt for training and/or fitness equipment is described.

An endless elastomeric belt is comprised of one or more reinforcement layers, and one or more elastomeric layers, wherein at least one of the reinforcement layers is formed of strips that are spirally wound forming a helix. A method of making an endless belt is provided and includes the steps of applying a first elastomeric layer on the outer circumferential surface of a belt building mandrel; splicing the ends together; applying a fabric reinforcement layer over the first layer, wherein said reinforcement layer is comprised of a continuous strip which is spirally wound around the mandrel to form a continuous, endless helix, and applying a second elastomeric layer over said fabric reinforcement layer, cutting the layers into one or more belts having a desired width, and then vulcanizing the one or more belts.
