20120329591 | BELT FOR DRIVING SYSTEMS, IN PARTICULAR A BELT-LIKE TENSILE ELEMENT FOR ELEVATOR SYSTEMS, HAVING FIRE-INHIBITING PROPERTIES - A belt for driving systems, including a belt body made of a polymeric material having elastic properties, which comprises a cover layer as a back of the belt and a foundation having a force-transmission zone, and, a tensile reinforcement embedded in the belt body. The belt body is made of at least two different materials A and B, namely: a first material A, which is provided with a fire-inhibiting additive and is used in the belt body everywhere the high mechanical properties are not required; and, a second material B, which contains little or none of a fire-inhibiting additive and is used in the area of the belt body that is subjected to great mechanical stress. The belt is used in particular as a tensile element for elevator systems. | 12-27-2012 |
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 |
20140243134 | BELT HAVING A TENSION MEMBER, IN PARTICULAR A CARBON TENSION MEMBER, WHICH IS PREPARED WITH A CROSS-LINKED POLYURETHANE, AND PREPARATION METHOD - A belt comprises at least a belt body made of a polymer material having elastic properties, the belt including a cover layer as a belt backing, a substructure having a force-transmission zone, and a tension member in a ribbed design embedded in the belt body. The tension member is prepared with a cross-linked polyurethane in such a way that the polyurethane fills at least part of the tension member cavities. The polyurethane filling material enters into a mechanical connection to the tension member on the one hand and an adhesive connection to the belt body on the other hand. The polyurethane filling material has a Shore A hardness that is 0.5 to 10 times harder than the Shore A hardness of the belt body. The belt body is preferably likewise made of cross-linked polyurethane, in particular using a carbon tension member. | 08-28-2014 |
20140370197 | DEVICE AND METHOD FOR PRODUCING REINFORCEMENTS - A device and a method for producing impregnated reinforcements, in particular for composite materials such as drive belts. The method for producing the reinforcements includes: introducing the reinforcement into an applicator device; introducing at least one substance for impregnating the reinforcement into the applicator device; and, embodying the impregnated reinforcement. The device comprises at least one applicator through which the reinforcement is guided and at least one intake for a substance for impregnation. | 12-18-2014 |
20150259176 | BELT FOR DRIVE TECHNOLOGY, PARTICULARLY A BELT-LIKE TRACTIVE ELEMENT FOR ELEVATOR TECHNOLOGY, WITH FIRE-RESISTANT PROPERTIES - A belt for drive technology having a belt body made from two polymer materials (A) and (B) with elastic properties and including a top layer as the belt back and a substructure with a force transfer zone and a tension member embedded in the belt body. The first material (A) contains 15 to 50% w/w of at least one fire-resistant additive and is used everywhere in the belt body where high mechanical properties are not required and the second material (B) contains 5 to 35% w/w of at least one fire-resistant additive and is used in the are of the belt body that is subjected to the highest mechanical stresses. The belt is particularly used as a tractive element for hoisting technology. | 09-17-2015 |
