Abstract
A single-level or multilevel or continuous board press is composed of a succession of press frames which are subdivided horizontally at their vertical limbs for transport and when then welded together at the erection site. Leveling strips are provided along mounted surfaces of the frame to support the plates, piston-and-cylinder units and the like serving to press the mats of wood material.
Claims15
A board press for producing pressed board, comprising:
- a press stand comprised of a plurality of upright press frames composed of steel plate and each having a generally horizontal upper limb, a generally horizontal lower limb and a pair of generally vertical lateral limbs interconnecting the upper and lower limbs, said frames each being subdivided horizontally into at least two segments and having at each lateral limb at least one welding gap between the two segments at which said segments are welded together, said upper limbs defining upper horizontal mounting surfaces and said lower limbs defining horizontal lower mounting surfaces;
- respective pressing members braced against said upper mounting surfaces and against said lower mounting surfaces and selected from press plates and piston-and-cylinder arrangements whereby board is pressed between said pressing members;
- and
- leveling strips between said mounting surfaces and said members for compensating for frame distortion.
A method of making frames for a board press for producing pressed board and wherein the press comprises a plurality of upright press frames composed of steel plate and each having a generally horizontal upper limb, a generally horizontal lower limb and a pair of generally vertical lateral limbs interconnecting the upper and lower limbs, said method comprising the steps of:
- (a) fabricating at least two frame segments of each frame such that each frame is subdivided horizontally and has at each lateral limb at least one welding gap between the two segments;
- (b) shipping said frame segments to a site at which the press is to be erected;
- (c) welding the segments of each frame together at said site by filling said gaps with weldment to form the frames of said press and such that said upper limbs define upper horizontal mounting surfaces and said lower limbs define horizontal lower mounting surfaces;
- and
- (d) affixing leveling strips on said upper horizontal mounting surfaces and said lower horizontal mounting surfaces for compensating for frame distortion.
A device for making frames for a board press for producing pressed board and wherein the press comprises a plurality of upright press frames composed of steel plate and each having a generally horizontal upper limb, a generally horizontal lower limb and a pair of generally vertical lateral limbs interconnecting the upper and lower limbs, said device comprising a positioning unit for receiving at least two frame segments of each frame such that each frame is subdivided horizontally and has at each lateral limb at least one welding gap between the two segments, said device comprising hold-down elements for retaining said segments and abutment surfaces for aligning said segments whereby said frame segments can be welded together at said site by filling said gaps with weldment to form the frames of said press.
