  • Patent number: 8528475
    Abstract: A method and apparatus for improving of wood veneer quality is provided. In the method, veneers are conveyed through a compression gap made up by two press elements, the gauge of said gap being adjustable. The method comprises the use of an endless felt assembly, which is adapted to circle around at least one of the press elements and which passes through the compression gap in such a way that at least one face of the veneer is brought against the felt assembly in said compression gap.

  • Patent number: 6848357
    Abstract: A method for controlling the temperature of a heated roll in a calender is provided. The calender comprises at least one heated roll or thermoroll and at least one backing roll, between which is formed a nip through which the material web is conveyed. To the heated roll is supplied internal thermal power by internal heating means of the roll, and external thermal power by external heating means of the roll. Before changing the heated roll, internal thermal power is minimized within a specific period by control means provided in conjunction with the internal heating means; external thermal power is maximized within a specific period by control means provided in conjunction with the external heating means; and the surface temperature of and/or the thermal power released by the heated roll, which corresponds to the surface temperature and/or thermal power desired for the grade of the material web, is maintained within a specific period.

  • Patent number: 6342115
    Abstract: A laminating heating module for use in a flatbed laminating machine. The heating module comprises an elongate body portion with at least one heating pad attached thereto. The heating pad is fabricated from silicone rubber and includes three separate heating zones for regulating the heat to the body portion. Attached to each heating zone of the heating pad is a respective thermocouple to control the temperature of each heating zone. The heating module further comprises a thermostat attached to the heating pad and operative to protect the temperature of the body portion of the heating module from overheating.

  • Patent number: 6264792
    Abstract: A method and apparatus for producing calendered paper by an on-line manufacturing system comprising at least a paper machine and a multi-nip calender. The method comprises following steps: removing water from a formed paper web by pressing, drying the pressed paper web by at least one dryer, calendering the dried web by the multi-nip calender, measuring a cross-machine moisture profile or a variable relative thereto, and altering the moisture of the web so that the moisture profile of the web in the cross-direction is even when the web enters the first nip of the calender.

  • Patent number: 6009803
    Abstract: A double press for making and/or coating of web-shaped or plate-shaped workpieces of all types includes a reaction zone in which the pressure load of the workpiece passing through the press, and the intensity of the heat transfer or the heat removal are designed to be adjustable for individual products over an extended range. Between the pressing rolls (9) and the pressure plate (6), there are disposed bearing rollers (10) associated with the pressing rolls. A liquid pressure-transmitting medium flows turbulently in a short circulatory loop through the pressure chamber and a heating or cooling unit (13) located outside the pressure chamber. The double band presses can be employed in the furniture and electrical industry as well as in other branches of industry where laminated materials are used or processed.

  • Patent number: 5979307
    Abstract: A double-belt system for processing viscous melts includes a driven upper belt having a lower working run, and a driven lower belt having an upper working run spaced beneath the lower working run to form a gap therewith for receiving a viscous melt. A gap-adjusting mechanism includes upper rollers engaging an upper surface of the lower working run, and lower rollers engaging a lower surface of the upper working run. A distance between the upper rollers and lower rollers is adjustable to vary a size of the gap. A compensation mechanism is disposed over the lower working run to apply an upward force thereto for pulling the lower working run against the upper rollers, thereby resisting sagging of the lower working run. At least one delivery mechanism applies a temperature-controlled liquid across an entire width of the lower working run for controlling a temperature thereof. The liquid is extracted by an extraction mechanism disposed downstream of the delivery mechanism.

  • Patent number: 5915295
    Abstract: A machine and method for manufacturing corrugated board, including several machines for applying heat to both sides of the corrugated board during the manufacturing process. Different types of heat exchangers may be used on the top and bottom sides of the moving surface to transfer sufficient heat to the moving surface, to remove moisture and to cure the adhesive of the corrugated board. Independently controlled heat exchangers enable the manufacturer to regulate the heat applied to the corrugated board across the width of the machine and in the direction of the machine flow, in response to varying the desired width and thickness of corrugated board. Unused areas of the hotplate section may be isolated to minimize the heat loss in the machine when narrow width corrugated board is manufactured.
