Abstract: A hot box comprises a lower hot-box portion and an upper hot-box portion. The lower hot-box portion comprises a lower housing, a lower heating plate, and a lower insulation layer. The lower heating plate is received within the lower housing and is configured to support a lower die. The lower insulation layer is positioned between the lower housing and the lower heating plate. The upper hot-box portion is positionable above the lower hot-box portion and comprises an upper housing, an upper heating plate, and an upper insulation layer. The upper heating plate is received within the upper housing and is configured to support an upper die. The upper insulation layer is positioned between the upper housing and the upper heating plate.

Abstract: A bonding machine for lamellar pieces of wood to be joined to a board has at least one clamping and pressing device and at least one drive. The clamping and pressing device has at least two pressing members which are configured to be loaded independently of one another against the board by a pressure force. The pressing members extend parallel to the pieces of wood and transversely to a feeding direction of the board. The drive has piston-cylinder units configured to adjust the pressing members.

Abstract: An apparatus for calendering a sheet material web being carried on or between one or more carrier fabrics. In a preferred embodiment, the apparatus includes a calender section having first and second calender rolls forming a nip therebetween. At least one carrier fabric is disposed between the first and second calender rolls. The first and second calender rolls apply a load to the carrier fabric and sheet material web as they pass through the nip between the calender rolls so as to reduce the caliper, or thickness, of the sheet material web. A method for calendering the sheet material web includes carrying the sheet material web on one or more carrier fabrics through the calender nip formed by the first and second calender rolls and applying a load to the carrier fabric, and sheet material carried thereby, so as to reduce the thickness of the sheet material web.

Abstract: A device for pressing and drying organic materials. The organic material is inserted between two sheets of thin cloth which are, in turn, sandwiched between two thick felt pads. These pads are then sandwiched between platens made from inorganic material. The assembly is heated, resulting in a pressed and dried organic material.

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.

Abstract: The present invention provides novel processes for the dewatering of a wide variety of solid-liquid matrices, including primary and secondary sludge, which involve the simultaneous application of pressure and heat to the solid-liquid matrices.
