摘要:
An applicator device and method where on the one hand adherence of particles in the dispensing area of the applicator nozzle, and on the other hand a thermal deflection of applicator device components can be prevented, or at least minimized. At least one thermal control channel through which a fluid flows is integrated into at least one of the two nozzle lips of the applicator device. Water or air can be used as temperature controlling fluids.
摘要:
A winding apparatus for transferring a web from a carrier drum to a spool. Pressure between the spool and the carrier drum is higher in the area of the feed strip of the web by applying a higher contact force, or by orienting the spool and drum at an angle to one another.
摘要:
A through-air dryer (TAD) fabric formed by interweaving of a warp yarn system with a weft yarn system. The TAD fabric has a paper side with a contact area between 20% and 30%. The warp yarn system includes flat warp yarns and/or the weft yarn system includes flat weft yarns which have not been subjected to a sanding process after weaving of the fabric and which have an aspect ratio of 1.15:1 to 1.35:1.
摘要:
Water draining device for a paper machine or the like, in particular for a felted press of such a paper machine, including a receiving tank extending at least essentially over the machine width. The receiving tank includes a first chamber that receives arriving water and is under ambient pressure, and a second chamber that is connected to the first chamber and is under vacuum, into which the water collecting in the first chamber is aspirated and from which the water is eventually drained. A water receiving device of improved efficiency is also provided by forming a water receiving device by at least one suction channel projecting into the wedge-shaped area between the upper press roll and the dewatering belt, and extending transverse to the pulp web, which suction channel is connected to a source of reduced pressure.
摘要:
A pulper to pulverize and suspend paper stock. The pulper includes a container open at the top with a cylindrical side wall and a driven rotor that is arranged in an off-center manner to the center of the container. The base of the container can be inclined toward the side wall.
摘要:
Method for changing properties of papermachine clothing, in particular a dryer fabric. The papermachine clothing is processed specifically, primarily in the transverse direction of the clothing, for the purpose of evening out the properties of the fabric. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
摘要:
A method for creating a pattern on or in an fabric, comprising producing a topographical polymer pattern on or in a papermachine fabric using a rotary screen. A fabric, comprising a papermachine fabric including a topographical polymer pattern as an external or internal feature. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
摘要:
A method of, and apparatus for, transferring a web, in particular a paper web or cardboard web or an insertion tail severed from the web, from a web-discharging web-guiding surface, via a web conveying apparatus, to the next structural unit of a machine for producing and/or handling the continuous paper web or cardboard web, the insertion tail is detached from the web-guiding surface by way of at least one brief high-energy air jet. The present invention provides that in the case of a web of high grammage, immediately once the tail has been detached from the web-guiding surface, the tail, which has been severed at least on a preliminary basis, is completely severed by an additional mechanical severing arrangement and, by way of its newly formed start, gripped, and passed on, by way of the web conveying apparatus.
摘要:
The invention relates to an element for forming a leading end of a web from a running material web, especially a paper or board web, having a certain width (B). The invention comprises an element which has a smaller width (BM) that the width (B) of the material web, and in that the element is embodied in such a way that a new leading end of a web is formed at the latest after said element as been introduced into a nip formed by a winding cylinder and the winding core, and is partially covered by the material web. The invention also relates to a method for forming a leading end of a web from a running web material web, especially a paper or board web, applied to a winding core, whereby at least one element is used according to the invention.
