摘要： The invention provides a web transfer belt, having good paper releasability, that can be produced with ease and at a low cost without increasing either its hardness or its weight, and a production process therefor. In one embodiment, the web transfer belt includes a high-molecular weight elastic member formed using a resin material mixed with microcapsules (alternatively, closed bubbles or closed bubbles created by a foaming agent), and having a web-receiving face for receiving a web P thereon to transfer, at whose web-receiving face there are provided a multitude of recesses having cut-openings of the microcapsules, such that a water film W easy to be formed between the web-receiving face and the web P can be broken by a large number of recesses.

摘要： Device and method for handling a material web, in which the material web is guided by at least one smooth support surface and is then guided together with a porous support belt to a deflection roll includes a suction box. The suction box has a wall opposite from the porous support belt, and creates a vacuum that draws the material web from the support surface to the porous support belt. The device also includes at least one sealing element positioned near a front end, in the web travel direction, the sealing element cooperating with the porous support belt, and a vacuum zone in which the vacuum is provided. The vacuum zone adjoins a side of the porous support belt not contacting the material web and is defined between the porous support belt, the at least one sealing element, the wall of the suction box, and at its rear end, the deflection roll. The device also includes a slot-shaped first suction opening provided in the suction box wall near the rear end of the vacuum zone adjacent to the deflection roll so that air can be aspirated from the vacuum through the first suction opening; and at least one additional suction opening communicating with the vacuum. The at least one additional suction opening is provided in the suction box wall.

摘要： In a paper making machine for manufacturing a material web (10), such as in particular a paper or cardboard web, the material web (10) to be manufactured is transferred on the surface of a transfer means (24) to a take-off position (30) in the region of which a preferably air-permeable belt (32) having an at least substantially open surface is guided over a take-off roll (34) or the like and takes off the material web (10) from the surface of the transfer means (24). A pressing gap (36) extended in the web running direction (L) is formed at the take-off position (30) with the surface of the transfer means (24, 60) facing the material web (10) being deflected in the region of the extended pressing gap, while forming an at least substantially concave depression (38), and also being pressed by a pressing force intentionally generated in the region of this deflection against the take-off roll (34) in order to thereby assist the take-off of the material web (10) from the surface of the transfer means.

摘要： A papermachine belt particularly for use in a press and/or dryer section comprises a support fabric, a minimal nonwoven layer on the support fabric, a fusible thermoplastic layer, and a thicker batt over the thermoplastic layer. The whole structure is needled together, and the thermoplastic layer melted so that it is expressed through the overlying batt. The layer may be substituted by a nonwoven fabric containing composite yarns with thermoplastic sheaths or such yarns wound spirally around the belt. The support fabric may be substituted by a perforated composite membrane.

摘要： Transfer belt for a paper machine, comprising a base structure (2) and a fiber batt layer (3) attached to the base structure and facing the fiber web. At least the fiber batt layer side of the belt is provided with a polymer matrix (4) impregnating the fiber batt layer (3). According to the idea of the invention, the transfer belt fiber batt layer comprises at least two fibers with different surface properties, the transfer belt surface facing the fiber web being thus provided with hydrophilic and, correspondingly, hydrophobic areas. The fibers in the fiber batt layer may differ from one another with regard to their polarity, hydrophilicity, electric charge, surface energy, friction properties, degree of fineness or porosity.
