| 20080289745 | METHOD FOR PRODUCING A STRETCH RESISTANT BELT - A belt having stretch reduction features is provided, along with a method for producing a belt having reduced stretch characteristics. The belt is formed of a jacket and a stretch reduction element. The stretch reduction element is formed of a material having a greater modulus of elasticity than the jacket. Additionally, the stretch reduction element is formed by bathing the stretch reduction element to a reactive fluid in an oxidizing atmosphere. | 11-27-2008 |
| 20090008025 | CONVEYOR BELT - A thermoplastic endless belt has a smooth outer surface substantially free of discontinuities and an inner surface with a plurality of teeth at a given belt pitch. The teeth are adapted to engage a sprocket with circumferentially spaced sheaves at a sprocket pitch greater than the belt pitch. The belt is slightly stretchable so that the sprocket can drive the endless belt when engaging the teeth within a range of load on the belt. The belt is preferred for use in conveyors in food processing industries where the smooth outer surface can transport food items and is easier to clean and keep free of impurities. | 01-08-2009 |

| 20100243130 | METHOD FOR PRODUCING A TRANSPORT/DRIVE BELT - A method for forming a longitudinal edge region of a transport/drive belt having at least two layers of a thermoplastic material and at least one layer of a woven fabric web includes positioning a mat at one longitudinal edge of the transport/drive belt. The method further includes transferring heat and pressure to the transport/drive belt so as to melt and merge at least a region of the at least two layers of thermoplastic material without adding any additional material, solidifying the at least two layers of thermoplastic material, and removing the mat. | 09-30-2010 |
| 20100243131 | MANUFACTURING METHOD OF DRIVING BELT - A manufacturing method of a driving belt, which can measure and adjust an endplay of the driving belt including a ring and elements to improve productivity of the driving belt, the method including: obtaining a correlation among a circumferential length of the ring, a total weight of the elements fastened by the ring, and a range of a movement of the fastened elements in the length direction of the ring; determining a range of a required element weight as a total weight of the elements to be fastened by the ring, on the basis of the obtained correlation, a desired moving range of the element, and the length of the ring; feeding the elements in the amount within the range of the required element weight while measuring a total weight of the element being fed; and fastening the element fed at the element feeding by the ring. | 09-30-2010 |
| 20110024024 | METHOD OF FABRICATING SUPER FINISHED ITB'S VIA INTERNAL MANDREL FLOW COATING - Provided are apparatuses and methods of making a transfer belt. The method can include providing a hollow mandrel including an interior surface and rotating about a longitudinal axis. The method can also include dispensing a coating liquid through a dispensing tip over the interior surface of the rotating mandrel and using a doctor blade to smooth the coating liquid to form a layer of coating. The method can further include curing the layer of coating to form a seamless belt over the interior surface of the mandrel and releasing the belt from the interior surface of the mandrel, wherein the belt has a thickness uniformity in the range of about 100 nm to about 1 um. | 02-03-2011 |
| 20110126964 | FABRIC ADHESION IMPROVEMENT FOR EPDM BASED LOW COST TIMING BELT - The present invention is directed to timing belts having improved fabric adhesion to the tooth facing which can be achieved by the use of a combination of a RFL treated fabric and an EPDM body provided the RFL treatment or the body include ZDA or the RF latex is an X-HNBR latex. | 06-02-2011 |
| 156138000 | Forming grooves on inner surface | 2 |
| 20130153123 | APPARATUS AND METHOD FOR MAKING ENDLESS REINFORCED BELTS - A system, method and apparatus for making endless belts having a profile layer, a fully embedded, helically wound, cord layer, and a top layer. The apparatus has a rotatable mandrel with a profile complementary to the belt profile, two or one engagement rolls adjacent the mandrel to maintain forced, wrapped engagement of the profile layer on a portion thereof; a cord applicator which may include a heated blade that plows a groove in the profile layer into which the cord is laid and fused thereto. A laminator applies the top layer onto the reinforced carcass. A system of buffer rolls handles the loose portion of the profile layer or carcass guiding it. | 06-20-2013 |
| 20140332144 | FABRIC ADHESION IMPROVEMENT FOR EPDM BASED LOW COST TIMING BELT - The present invention is directed to timing belts having improved fabric adhesion to the tooth facing which can be achieved by the use of a combination of a RFL treated fabric and an EPDM body provided the RFL treatment or the body include ZDA or the RF latex is an X-HNBR latex. | 11-13-2014 |
| 156139000 | "V" or trapezoid section belt | 3 |
| 20080196818 | Elastically Extensible Poly-V Transmission Belt for Driving Accessories of an Internal Combustion Engine - Poly-V belt, particularly for driving accessories of an internal combustion engine, comprising a cord realised from a yarn composed of a plurality of filaments by means of a first twisting in which are formed at least two plied yarns each composed of at least one yarn and a second twisting in which the plied yarns are twisted together to form the cord; the first twisting and the second twisting are made in opposite directions, and the numbers of twists per metre of the two twisting steps are calculated so that in the finished cord the filaments form with the axis of the cord an angle smaller than 3.3°. | 08-21-2008 |
| 20140238581 | METHOD FOR PREPARING A TENSION MEMBER, IN PARTICULAR A CARBON TENSION MEMBER, IN THE PRODUCTION OF A BELT - A method for treating a tension member in the production of a belt. The belt includes at least a belt body made of a polymer material having elastic properties, a cover layer as a belt backing, and a substructure having a force-transmission zone. The tension member has a ribbed design and is embedded in the belt body. The tension member is treated with an overall treatment mixture which forms a cross-linked polymer that on the one hand enters into a mechanical connection with the tension member and on the other hand forms an adhesive connection with the belt body. | 08-28-2014 |
| 156140000 | With plastic shaping or molding | 1 |
| 20160121567 | RUBBER V-BELT EXTRUSION MOLDING APPARATUS AND METHOD - Rubber V-belt extrusion molding apparatus and method are described herein. The rubber V-belt extrusion molding apparatus includes an extrusion device, a conveying belt, a cooling device, a storage device, a detection device, a rubber coating and cutting device, and a canvas wrapping device. A material is extruded by the extrusion device to form base compound rubber. The conveying belt conveys the base compound rubber. The cooling device cools the base compound rubber on the conveying belt. The storage device stores the base compound rubber cooled by the cooling device and conveys the base compound rubber to the rubber coating and cutting device. The detection device detects the cooled base compound rubber before storing. The rubber coating and cutting device coats a yarn blank with the base compound rubber conveyed by the storage device to form a yarn core. The canvas wrapping device wraps the yarn core with a rubberized canvas. | 05-05-2016 |
