Definitions

  • the invention relates to a device for producing a fold-up sheet, such as e.g. a map or a plan, said sheet being provided with a number of zigzag-shaped folding lines extending parallel to each other, whereby the sheet parts bounding a folding line can be folded relative to each other about a folding line, in a direction opposite to the direction in which sheet parts bounding an adjacent folding line can be folded relative to said adjacent folding line, and with further folding lines extending parallel to each other, transversely to the zigzag-shaped folding lines, said further folding lines extending through the corner points in which each time two adjacent parts of the zigzag-shaped folding lines join each other, whereby the sheet parts which are located on both sides of a first part of a further folding line, which first part extends between two adjacent zigzag-shaped folding lines, can be folded relative to each other about said first part of the further folding line, in a direction opposite to the direction in which the sheet parts, which are located on both sides of a further part of the further folding line joining said
  • Such a map and a device for producing such a map are known from the Japanese publication No. 151460, which was deposited for public inspection in 1980.
  • the device disclosed in said publication comprises two opposed endless bands, each carrying a number of blocks.
  • the blocks of the two bands are made such that the blocks mounted on opposed parts of the two bands engage each other.
  • a sheet to be folded must be passed between the bands in order to be folded by the engaging blocks.
  • Said device has a complicated construction and in practice it has become apparent that it is not possible to fold a sheet correctly and accuretely by means of said device.
  • the object of the present invention is to obtain a device of the above kind, by means of which a sheet can be efficiently and effectively folded in the desired manner.
  • the device comprises a forming block having a boundary plane built up of forming surfaces, which slope downwards from a number of zigzag-­shaped boundary lines extending parallel to each other and being located in one plane, and which intersect each other according to a number of further lines, which are located in a second plane extending parallel to the first plane and which extend zigzag-shaped and parallel to the former zigzag-shaped lines, and according to lines extending between the corner points where the parts of the zigzag-shaped lines including an angle with each other intersect, whilst there are provided a number of stamps, which are movable up and down relative to the forming block, whereby the side of each stamp facing the forming block is designed such that said side fits on a forming surface sloping downwards from a zigzag-shaped boundary line at one side of said boundary line.
  • the sheet illustrated in Fig 1 which e.g. constitutes a map, a plan or the like, is provided with a number of zigzag-shaped folding lines 1 extending parallel to each other, said folding lines alternately being shown as full lines and dotted lines.
  • the parts of the sheet located on both sides of a full folding line can be folded in one direction relative to said folding line, such that the sides of said parts of the sheet located at the bottom side of the sheet, seen in fig. 1, will come to lie against each other.
  • the parts of the sheet located on both sides of a dotted folding line can be folded with respect to each other from the flat position of the sheet in an opposite direction, i.e. such that the upper sides the sheet parts bounding the dotted folding line, seen in Fig 1, will come to lie against each other when the sheet is being folded.
  • Fig 1 there are provided further folding lines 2 in the sheet, said folding lines extending transverse to the folding lines 1, between the corner points in which the parts of the folding lines 1 including an angle with each other join each other.
  • a folding line 2 is built up of parts extending between the folding lines 1 and the edges of the sheet, respectively, said parts alternately being indicated by means of dotted lines and full lines.
  • the sheet parts located on both sides of a dotted part of a folding line 2 can again be pivoted relative to each other about the folding line 2, such that the upper sides of the sheet parts in question, seen in Fig 1, will come to lie against each other when the sheet is being folded.
  • the sheet parts located on both sides of a full part of a folding line 2 will come to lie against each other with their lower sides, seen in Fig 1, when the sheet is being folded.
  • the device comprises a frame 3 provided with a table 4 which is vertically adjustable by means of a driving mechanism 5.
  • a forming block 6 is supported on the table.
  • Said forming block 6 is provided with a few ribs 7 having a triangular cross-section, which are arranged side by side and which extend perpendicularly to the plane of the drawing, seen in Fig 2, said ribs being bounded at their upper sides by a number of zigzag-­shaped boundary lines 8 which are located in a horizontal plane.
  • Forming surfaces 9 slope downwards from said zigzag-shaped boundary lines 8, in the direction of further zigzag-shaped boundary lines 10 which are located also in a horizontal plane.
  • Each forming surface 9 is furthermore bounded by two boundary lines 11, which extend between the corner points where the parts of the zigzag-shaped lines 8 and 10 including an angle with each other intersect.
  • stamps 12 - 18 which are each connected, by means of a vertically extending connecting rod 19, with a driving mechanism 20, by means of which the stamps 12 - 18 can be moved up and down independently.
  • each stamp 12 - 18 is equal to the length of the forming block 6, measured in a direction perpendicular to the plane of the drawing in Fig 2.
  • the boundary side of each stamp 12 - 18 thereby furthermore corresponds with the design and arrangement of the forming surfaces 9 located thereunder, so that each 12 - 18 can be brought into close abutment with the row of forming surfaces 9 located thereunder and extending perpendicularly to the plane of the drawing in Fig 2.
  • a sheet to be folded can be put on top of the forming block 6 by means of a supply device (not shown), such that said sheet rests on the zigzag-shaped boundary edges 8.
  • the stamps 12 - 18 are adjusted such that the lowermost points of said stamps 12 - 18 at least substantially rest on said sheet, so that the sheet cannot make any undesired upward movements.
  • the stamps 12 - 18 are moved downwards one by one, until they abut the forming surfaces 9 of the forming block 6 located thereunder, starting with the stamp 12.
  • the stamp 12 is moved downwards first, therefore, in order to press the left-hand end, seen in Fig 2, of the sheet resting on the forming block 6 against the most left-hand row, seen in Fig 2, of forming surfaces 9 located behind each other, by means of the stamp 12.
  • the stamp 13 is moved downwards in order to press a following part of the sheet against the following row of forming surfaces 9, etc.
