Definitions

  • the main idea of this invention consists in employing the coating or facing sheets, designed to be pressed with the rough particle blank, also for the transport of the blanks and for the insertion of the latter into the press.
  • particle blanks are formed separately on the coating sheets or coating films and the thus prepared blanks are transported by means of these coating sheets or films and inserted into the open press.
  • the blanks with the coating sheets, serving for their transport and loading the press are united together into compact boards.
  • the coating sheets or faces fulfill two functions in the method according to this invention: first, they serve as a support during the distribution or the felting of the particles while a blank is preformed, and subsequently for the insertion of this blank into a press. Secondly, thecoating sheets then serve, in another stage of the method, as supports during pressing, and at the same time being joined or bonded with the prefabricated or preformed blanks in the form of compact boards.
  • the invention also includes equipment for carrying out the above method.
  • This equipment is characterized by means for bringing coating sheets to a point of formation of particle blanks and by pulling means with pincers or similar members gripping the sheets for the transport of these sheets loaded with the preformed blanks from said point into the open press.
  • a single stage press To the right of the drawing is shown a single stage press. It consists of two hydraulic cylinders 3 mounted in a pit 2 formed in a base 1, these cylinders being fed with oil under pressure through ducts not shown. Press pistons 4 mounted in these cylinders support a lower press table 5. The upper press table is shown at 6. Heated press slabs 7 and 8 are integral with the press tables 5 and 6 respectively, these heated slabs having, for example, holes for the flow of a heating fluid. A distribution point 11 endowed with reciprocating motion is disposed in front of the press. Such distribution points are known which permit, for example, of distributing in several passages wood shavings for producing a blank of several layers on a stationary support.
  • this distribution takes place on a sheet of newsprint paper 9 which, during this operation, rests on a stationary table 18.
  • the paper sheets are separated from a strip issuing from a roller 12, through the agency of a cutting device 13 and have a width which slightly exceeds that of the blank to be produced.
  • the carrying out of the method with the equipment described is of the simplest.
  • the end of the paper strip issuing from the roller 12 is gripped by a pincher 17 and a sheet is cut into sections by the cutting device 13, as soon as this pincer has been moved a predetermined amount by the chain 14.
  • the chain conveyor is stopped, and the distribution point 11 is moved to and fro in order to distribute particles on the sheet 9 which is under the said point. During this period the press is closed.
  • the sheet 9 extending under the distribution point 11 together with the performed blank thereon is pulled by means of a pincer 17 fixed to the chain 14 again in motion, so as to be brought into the empty and open press while, simultaneously, another coating sheet is brought under the distribution point 11.
  • the corresponding pincer opens and the lower press table 5 is raised hydraulically.
  • the coating sheets 9 and the blank 10 are pressed so as to form an inseparable whole.
  • a single stage press is employed.
  • a multi-stage press it is necessary to dispose a loading frame which moves upwardly and downwardly next to the press.
  • sheets are brought to the distribution point 11, these sheets being separated over a predetermined length.
  • the blanks consist of relatively coarse wood particles, one must arrange between the coating sheets and the blank a levelling wad-layer of very fine material such as wood-dust, sawdust and the like.
