Definitions

  • This invention relates to the production on fibrous cement sheets and is concerned more par- J ticularly with a novel method of cutting a continuously moving fibrous cement web into sheets and stacking the sheets, and with an apparatus, by which the method may be advantageously practiced.
  • Fibrous cement webs of indefinite length can be made by apparatus of various kinds and the webs so formed are cut into sheets, which are allowed to set and harden.
  • the sheets cut from the freshly made web are diflicult to handle because of their size, and they are readily damaged because of their softness, particularly when they are relatively thin.
  • the sheets have been handled manually and the operations are slow and laborious and involve a considerable loss of material as 'a result of damage thereto.
  • the present invention is directed to the provision of a method, by which a fibrous cement web being continuous1y-advanc:d from the apparatus in which it is produced, can be cut-into sheets and the sheets stacked or piled on a truck or conveyor without manual handling of the finished sheets.
  • the indefinitely long web is advanced continuously over a support and is cut into sheets by a cutter, which travels across the support and back at such an angle less than 90 to the direction of movement of the web, that the sheets are rectangular in shape.
  • the sheets advance upon the top of a discharge table, which is capable of being tilted on an axis parallel to its top and also raised and lowered.
  • the top surfaccs of the support and table are pervious and air under pressure may be passed through the pervious surfaces from beneath to facilitate the movement of the sheets over the surfaces.
  • the air supply to the surface of the table is cut off and suction is applied to the under side of the sheet through the table top, these operations being performed manually.
  • the table is then rotated on its axis with the sheet held tightly in place thereon by the suction and, when the table is upside down, it is lower;d to place the sheet upon a truck or conveyor.
  • the suction is then out off to release the sheet and the table raised and rotated to its
  • the and table may be facilitated by so mounting the support and table, that thcir tops are inclined downwardly in the direction of travel of the web and sheets.
