The invention relates to a device for the continuous production of plate-shaped products, comprising two endless strips which are positioned one above the other and can be driven. A working gap is formed between the sides of said endless strips, said sides being adjacent to one another and each being conveyed via a support surface. The starting material for processing is conveyed through said working gap which is bordered on each side by an accompanying strip. Said accompanying strip is situated along said working gap between the two endless strips and moves with them, consisting of a flexible sealing strip which has a friction surface on at least one face, said face facing towards an endless strip. Said friction surface increases the static friction between the flexible sealing strip and the endless strip.

Device for continuous production of plate-shaped products

A continuously operating press is described for the manufacture and/or coating of board webs consisting of a fleece or mat in which the press belts are supported on a lubricant film formed on a slide lining. For the marginal width adjustment of the press zone the slide linings are subdivided into a main zone and adjoining marginal strip zones respectively. In one embodiment of the invention transition zones are in each case provided between two of these slide lining zones and are either made groove-free or provided with blind grooves, which serve neither as supply nor as discharge for lubricant. In a further embodiment of the invention adjacent grooves in these slide lining zones are alternatively provided with supply and discharge openings for the lubricant.

Continuously operating double-belt press

A lubrication system for a continuously operating press for the pressing of a multi-ply board web (119) of pre-manufactured material has a press gap defined between upper and lower runs of endless recirculating steel press bands (105). A slide coating (101) which extends over the width of the press zone is provided with grooves. Each press band (105) slides by means of a lubricant which is supplied into the slide coating via supply lines and is led away through discharge openings. Several grooves (107, 108, 110, 111) for the swirling of the lubricant are provided for the press band (105) at least in the two outer longitudinal edge regions of the slide coating.
