    摘要: A process and installation for the continuous production of boards of wood-based material, includes the steps of forming on a continuously moving scattering belt, a pressed material mat includes an initial mixture of chips and/or fibers from a scattering station and mixed with binder; precompacting and preheating the pressed material mat between the scattering station and a main pressing region; and bringing into an end form and curing the pressed material with the application of pressure and heat in a main pressing regions. The moisture level of the pressed material mat is less on entry into the main pressing region than the moisture level of the initial mixture in the scattering of the pressed material mat, part of the moisture imparted to it in the scattering being extracted again by hot-air preheating.

    摘要: A continuously operating press for the production of particleboards, fiberboards or similar wooden-material boards and plastic sheets allows for the free longitudinal expansion or contraction of the press heating plates by having a press force frame structure of individual press frames positioned between support carriers and mounted on sliding members on the lower support carriers. The sliding members are designed as rolling wheel segments that are assigned to each individual frame of the press force support structure.

    摘要: Veneer panels which are to be joined in a plurality of layers one above the other and one behind the other are assembled and glued to form an endless strand of veneer laminates. In the process, the veneer panels are first fed in through a glue-application machine which applies a layer of glue on a top side of the veneer panels onto a buffer belt. The veneer panels are then transferred from the buffer belt to a horizontally reversing feed belt which forms on a roller table a first veneer assembly comprising a plurality of veneer panels. The first veneer assembly is raised about its front end by an angle .alpha. into an oblique position so that veneer panels of a subsequent veneer assembly can be threaded into the first veneer assembly using the horizontally reversing feed belt. The first and subsequent veneer assemblies are thereby combined into a veneer-panel strand, and transferred to a continuously operating prepress and press.

    摘要: A method of controlling the press force on at least one press heating plate along the press length of an operating cycle. For a reduction of specific press force from a maximum press force towards a zero press force, a setting force for a longitudinal deformation of the at least one press heating plate is increased accordingly. For an increase in the specific press force from a zero press force towards a maximum press force, the setting force for the longitudinal deformation of the press heating plates is reduced accordingly. For a reduction of the specific press force from the maximum press force towards the zero press force, the longitudinal gradient tan .beta. is set to be approximately twice as large as the gradient tan .alpha. at the press force maximum. The longitudinal gradient and setting force can thus be controlled along an entire pressing path for an increase or decrease in the specific press force.

    摘要: A continuously operating press produces particle, fiber, plastic and wood boards continuously from pressing stock. The press includes a heating platen provided on one side of the press and a plurality of press platen segments arranged on a side opposite to the heating platen. The press platen segments are resiliently coupled to one another by snap-action hinges and the separation space between the press platen segments and the heating platen is independently adjusted. The pressing stock is pulled through the separation space which has been optimally controlled to produce boards with desired density profiles at a maximum production speed.

    摘要: A continuously operating press for the production of particle boards, fiber boards and similar wood boards and plastic boards, wherein a spherical geometrical deformation of the press/heating platen in the longitudinal and transverse directions with the hydraulic actuators in positive or non-positive engagement with the press/heating platen is set during start-up or production by means of different actuating forces in the longitudinal and transverse directions, the setting process being independent of the reaction forces of pressing stock, wherein, to allow a convex bending deformation to be set at the maximum pressing force, the central actuators in each row of actuators are dimensioned to give 105% to about 150% of the maximum pressing force in relation to the outer actuators, and wherein each row of actuators has a position sensor system comprising a feeler rod, a reference gauge bar, a lever mechanism and a measured-value transmitter with a position sensor for the press-nip actual value in the center of the press/heating platen arranged between the web plates, underneath the actuators and outside the area in which the heat might exert a critical influence.

    摘要: A method and apparatus for pressing an article includes a press arm and a press platen defining a pressing region positioned therebetween. First and second endless steel bands transmit a pressing force to an article to be pressed and draw the article through the press. A plurality of co-rotating rolling rods support the steel bands as they travel through the press. The rolling rods are introduced to an entry region of the press orthogonally relative to a longitudinal center of the press. First and second resilient pressure holding plates located in the entry region adjacent the press platen and the press ram, respectively, impose a pressure on the rolling rods that progressively increases as the rolling rods pass through the entry region.

    摘要: A collet surface structure is provided for a high-speed hydraulic press having collet interlock in order to eliminate leakage of oil into the clamping region. Furthermore, the formation of a harmful hydrostatic film thickness from the lubricating-oil film between the pressure rods and the collets is prevented, since the oil is immediately forced away due to the high clamping pressure between the clamping faces. These high clamping pressures result from the extremely short space of the lubricating-oil elimination grooves and the large capacity of the grooves. Thus, the oil-eliminating grooves are made large enough to eliminate reliably a hydrostatic oil film of at least 0.1 mm. This regularity is independent of the clamping diameter of the collet.
