Abstract

A short cycle press for glueing together compressed carrier panels and upper and lower side facing layers of curable resin or resin films, papers or veneers has piston and cylinder units (2,3) arranged in a row along the central axis (I-I) of a press frame (9). The pistons (3) act against two rectangular cross-section beams (4) to form two pressure application lines (II-II; III-III), one at each side of the central axis (I-I), at the rear of the moveable upper heating platen (5). Spacing between the pressure application lines (II-II; III-III) and the length and breadth of the beams (4) are chosen to give the optimum uniform pressure distribution over the entire surface of the heating platen (5).

Claims (4)

10 15 20 25 30 (fl ._\ TO __; -lš- \Û 2 en önskad tryckfördelning i den övre press- och värmeplattan 5 skall åstadkommas. Press- kolvcylinderaggregaten kan skyddas genom att tryckytorna på tryckbalkarna 4 förses med värmeisolerande remsor 8, som tål högt tryck. Uppfinningen kan med fördel utnyttjas vid både en- och fleretagepressar och vid kontinuerliga pressar. Trycket från tryckkolvarna 3 fördelas på tryckbalkarna 4 av mellan dessa delar anord- nade tryckiördelarplattor 10. Tryckfördelaiplattorna 10 är företrädesvis bredare än cylind- rarnas ytterdiameter och försedda med skenor på undersidan. Därigenom kan pressen ställas in och anpassas till olika pressgodsbredder och olika tryck längs den övre press- och värme- plattan 5 genom att tryckbalkarna 4, och därmed presstrycklinjerna II-II och III-III, ställs om längs skenorna. Patentkrav10 15 20 25 30 (fl ._ \ TO __; -lš- \ Û 2 a desired pressure distribution in the upper press and heating plate 5 must be achieved. The press piston cylinder assemblies can be protected by providing the pressure surfaces on the pressure beams 4 with heat-insulating strips 8, The pressure can be used to advantage in both single- and double-presses and in continuous presses. Thereby the press can be adjusted and adapted to different press material widths and different pressures along the upper press and heating plate 5 by adjusting the pressure beams 4, and thus the press pressure lines II-II and III-III, along the rails. Patent claims 1. Kortcykelpress för limning av skiktformigt pressgods (7), som består av bärplattor med på ovan- och undersidan pålagda täckskikt av härdbar plast, härdbar plastfolie, papper eller faner, med ett presstativ (9) och mot detta stödjande presskolvcylinderaggregat (2, 3), som under arbetsdelcykeln trycker en värmd rörlig övre pressplatta (5) i riktning mot en värmd fast undre pressplatta (6), kånnetecknad av att presskolvcylinderaggregaten (2, 3) är anordnade i presstativet (9) i en rad längs den längsgående mittlinjen (I-I), att tryckkolven (3) i varje presskolvcylinderaggregat (2, 3) är anordnad att med två rektangulära tryckbalkar (4) trycka mot den värmda rörliga övre pressplattan på sådant sätt att tryckbalkarnas (4) längsytor till höger och vänster om den längsgående mittlinjen (I-I) bildar var sin presstryck- linje (Il-II och III-III) längs den värmda rörliga pressplattan, och att avståndet (X) mellan de båda presstrycklinjerna (II-II, III-III) och tryckbalkarnas (4) längd (L) och bredd (B) kan väljas enligt den önskade presstrycksprofilen så att yttrycket fördelas likformigt över den rörliga pressplattans (5) hela yta.Short cycle press for gluing layered press material (7), consisting of support plates with cover layers of hardenable plastic, hardenable plastic foil, paper or veneer applied to the top and bottom, with a press frame (9) and against this supporting piston piston cylinder assembly (2, 3 ), which during the working part cycle pushes a heated movable upper press plate (5) in the direction of a heated fixed lower press plate (6), characterized in that the press piston cylinder assemblies (2, 3) are arranged in the press frame (9) in a row along the longitudinal center line ( II), that the pressure piston (3) in each press piston cylinder assembly (2, 3) is arranged to press with two rectangular pressure beams (4) against the heated movable upper press plate in such a way that the longitudinal surfaces of the pressure beams (4) to the right and left of the longitudinal center line (II) each forms a press pressure line (II-II and III-III) along the heated movable press plate, and that the distance (X) between the two press pressure lines (II-II, III-III) and the length of the pressure beams (4) ( L) and width (B) can be selected according to the desired press pressure coil so that the surface pressure is uniformly distributed over the entire surface of the movable press plate (5). 2. Kortcykelpress enligt kravet 1, kännetecknar! av att tryckbalkarnas (4) tryckytor är försedda med värmeisolerande isoleringsremsor (8), som tål högt tryck.Short-circuit press according to claim 1, characterized! because the pressure surfaces of the pressure beams (4) are provided with heat-insulating insulating strips (8), which can withstand high pressure. 3. Kortcykelpress enligt kravet 1 eller 2, kännetecknad av att kortcykelpressen är utformad som en en- eller fleretagepress eller som en kontinuerlig press.Short-cycle press according to Claim 1 or 2, characterized in that the short-cycle press is designed as a single- or multi-storey press or as a continuous press. 4. Kortcykelpress enligt något av kraven 1 till 3, kånneiecknad av att en mellan tryck- kolven (3) och tryckbalkarna (4) i varje tryckkolvcylinderaggregat anordnad tryckfördel- ningsplatta (10) har större bredd än cylinderns diameter och är försedd med skenor, längs vilka tryckbalkarna (4) kan förflyttas, så att presstrycklinjernas (II-II, III-III) lägen kan ändras.A short-cycle press according to any one of claims 1 to 3, characterized in that a pressure distribution plate (10) arranged between the pressure piston (3) and the pressure beams (4) in each piston-cylinder assembly has a width wider than the diameter of the cylinder and is provided with rails, along which the pressure beams (4) can be moved, so that the positions of the press pressure lines (II-II, III-III) can be changed.
