Double backer corrugator. It describes that the doublebacker holds the liner and web together with minimal pressure to bond them across the board and edges. </p> <p>As one of the key machines in the corrugating process, BW Papersystems’ Cool-Vac Doublefacer exceeds expectations. the machinery. A double-facer, or double backer, is the part of a corrugator which bonds single-face board to another liner to produce a double-faced corrugated sheet. Sep 7, 2017 · Double-facer: A double-facer, or double backer, is the part of a corrugator which bonds single-face board to another liner. By The Pro/Active will therefore continuously automatically set and adjust all such settings such as the variable wrap arm positions, steam pressures along the corrugator, steam showers, all glue gaps, double backer steam shoe pressure settings as well as the paper tensions in the splicers and at the bridge brake. This refers to the wave shapes, or ridges, that are pressed into a sheet of material that has been softened by steam. The document discusses the operation of a corrugator doublebacker machine. With multiple installations around the world on old and new Corrugators AirBond leads The Corrugator is a combination of many individual machines brought together to make one very complicated, yet synchronized, piece of machinery which is used for the conversion of the paper into different types of board. In fact, most corrugating machines are built with two sets of corrugating rolls and prevision for making double wall board. The Double Facer from BHS Corrugated does it all – from micro-flute to heavy triple-corrugated board. This creates a three-layered structure, with the linerboards acting as the outer layers, and the corrugated medium providing the strength and cushioning in between. Double backer belts Bluebacker Corrugator Belt The new generation HybridMesh has an open and robust mesh structure that reduce noise emissions and increases traction features. Folding Cartons: Multi-layer paperboard cartons which are printed or coated and cut into carton blanks. . The double facer designed for corrugator cardboard drying purpose. Ideally, it should be automatic to turn on when speed is achieved. The surface features ensure safe traction of the corrugated board during the whole bonding process. The corrugated fluting medium with one liner attached to it is called single face web and travels along the machine towards the double backer where the single face web meets the outer liner and forms a continuous web of single wall rigid corrugated board, which is then cut to length and width and stacked. Hot plates which dry the board and set the starch before the finishing processes. Heats the adhesive close to the gel point to facilitate bonding at the double backer. The shoes are made from high quality stainless steel to enable consistent and even surface pressure contact to be applied and therefore even heat transfer across the width of the heating plates. When carriage speeds and time under pressure are selected, the double-backer simulator can simulate a broad range of corrugator speeds. This produces a double-faced corrugated sheet. Adhesive is applied to the fluted medium’s exposed tips, and the double backer presses the outer liner into place, forming a sturdy, double-faced corrugated board. In this area, the bound single-faced corrugated board web and the outer paper web are merged and glued together. com Double Backer: After the adhesive is applied, the corrugated medium is sandwiched between two linerboards at the double backer. This is suitable for universal use on double facer machinery. Explore solutions and insights for double backer defects in corrugated manufacturing to improve product quality and efficiency. Key factors that must be The AirBond Double Backer Heat Transfer System is manufactured using folded aluminium, providing maximum rigidity. txt) or view presentation slides online. See full list on corrquest. Should only be use at speeds greater than 300 fpm. This machine utilizes Fosber’s advanced Syncro automatic control with cast iron hot plates, automatic width adjustment, and recipe-based control. The hot plates in corrugating machines have basically remained unchanged for nearly a century. Doublebacker Issues by Croker - Free download as Powerpoint Presentation (. After this process they are dried by feeding through a steam-heated load system. le, double, or triple corrugated cardboard. To make double wall board, another single facer,bridge and double backer gluing station would have to be installed on the machine. A typical corrugator producing double walled board consists of two single facer units with a double backer section, all using steam at various pressures. The different pieces of equipment which basically make up the Corrugator are as follows:- SINGLE FACER (one for B flute and one for C flute) DOUBLE BACKER HEATING SECTION Jan 25, 2025 · Double Backer: Here, the single-faced board is combined with an outer liner. Hot-plate steam pressures are variable from 7-220 psi and can be 9 to 20 plate configurations <p>BW Papersystems is a leading manufacturer of products used by the corrugating, sheeting, and paper-converting industries. Application Requirement: The double backer machine glues the outer liner to cardboard fluting to obtain sin. pptx), PDF File (. Steam sprays which heat, moisten and clean the double backer felt. The cell guarding the doub. ppt / . pdf), Text File (. On the corrugating side, BW Papersystems is represented by the well-known brand MarquipWardUnited to create a full line of corrugators. The Express 400 DoubleFacer is a high-speed machine offering flexibility in configuration, installation, machine features, and speeds up to 1500 ft/min. How productive your corrugator is largely depends on the performance of your Double Facer, especially in markets with a high proportion of double flutes. 2. A schematic of the operation of the simulator is shown in Fig.
