Definitions

  • FIG-1 RuuRp BOEIJINGA INVEN TOR.
  • the invention relates to an aligning device intended to be used for the preparation of printing forms, particularly the fitting and aligning of printing plates or blocks.
  • Aligning devices which are provided with straight guides arranged at right angles to each other are known per se.
  • fitting chases are known at one of the edges of which a sheet of transparent material is attached.
  • Such a fitting chase is put on a fiat base, whereupon a printing form is placed within the chase after folding back the sheet of transparent material.
  • On the sheet of transparent material, which is turned forward and comes to rest on this original a few characteristic lines of the original are copied or a print of the original is made on the bottom face of the transparent by coating this face with ink before turning the transparent sheet forward.
  • After the copying of the original on the transparent the original lying below it is removed and in its place are arranged printing blocks of which the final printing form is to be composed.
  • the lines or the copy made on the transparent sheet should correspond to corresponding lines of the images on the printing blocks. This means that the transparent sheet must always be lifted again and the blocks below it always must be shifted in order to obtain the correct arrangement of the blocks, and with a large printing form these can be fitted in sections only. It is clear that because of these requirements the fitting and aligning oi the printing blocks require much time and that the production process in the printing plant cannot proceed efficiently. These drawbacks occur in particular with prints in two or more colors, the correct determination of the position of each color being very important.
  • the invention has as an object the overcoming of the drawbacks mentioned and to provide an aligning device by means of which the compositor at the start of the technical operations is able to compose with a small apparatus, mounted above two fixed lay-out galleys, and the composing forms can be fitted on or in each other in a shorter time than necessary heretofore.
  • the device also makes it possible to work from a drawing or an old printed model. The exact fitting, correct placing and placing at right angles, and gluing or nailing together takes place by the form preparer when the form is composed in the size necessary for printing, by another larger apparatus. At the same time an economization in the costs of the blocks may be obtained.
  • the sheet of transparent material is attached to an element which is movable in two directions.
  • the sheet of transparent material is attached detachably and foldably to an element which is movable in two directions perpendicular to each other, the movement in one of these directions being limited by two adjustable abutments which together can be displaced while being kept spaced at a constant mutual distance.
  • the apparatus according to the invention it is possible to transfer the characteristic lines of an original, such as a drawing, first print or first composing or printing form (masterform) or old printed model, made on the transparent material, to the composing and/ or printing form of blocks so that the correct position of blocks can be determined and it can be ascertained whether the ice printing blocks are squared and aligned.
  • the device according to the invention is also suitable for use as a repetition device for the determination of the position of a number of loose printing blocks in a printing form.
  • the element with the sheet of transparent material is guided on a first rod which itself can be displaced with respect to a second rod with the aid of a guiding sleeve which is connected with the first rod and which [can be displaced along the second rod, both rods being perpendicular with respect to each other.
  • the two abutments on the said second rod can also be adjusted and fixed on a third rod which is parallel to the second rod and can be longitudinally displaced relative thereto.
  • FIGURE 1 is a top view of the aligning device according to the invention.
  • FIGURE 2 is a side view of this device.
  • a sheet of transparent material 1 is clamped between the two halves of a guiding sleeve 2, which is divided in the longitudanal direction, by means of bolts 3 connecting both halves of the sleeve to each other.
  • the guiding sleeve 2 can. be shifted along a rod 4 and be fixed on this rod with the aid of :a set bolt 5.
  • the rod 4 is attached to a second guiding sleeve 6 which can be shifted along a second rod 7 and can be fixed on this rod with the aid of a set bolt 8.
  • the rod 7 is stationarily attached to a printers table (not shown).
  • the set bolt 8 and, if desired, the set bolt 5 may be spring loaded in such a manner that when the set bolt is pressed down the guiding sleeve can be shifted along the rod and on releasing the bolt the sleeve is clamped on the rod.
  • the rods 4 and 7 are arranged at right angles to each other, provisions having been made to be able to readjust the rods at right angles to each other in case of wear of the bore of the sleeve 6.
  • the attachment of the rod 4 to the guiding sleeve 6 is by means of two bolts 9 and 10, of which the one bolt 9 is arranged in a slot in such a manner that after loosening the bolts 9 and 16 the rod 4 can be swung with respect to the sleeve 6, the bolt 10 then acting as a pivot.
  • the movement of the guiding sleeve 6 is limited by two abutments 11, 12 which can be displaced and fixed on the rod 7. These abutments also can be shifted along a third rod 13 and fixed thereon.
  • the rod 13 is arranged parallel to the rod 7 and can be displaced longitudinally with respect to this rod.
  • Ball bearings 14 are arranged on the guiding sleeve 6 for supporting the sleeve.
  • the bearings 14 rest on the printers plate and prevent sagging of the rod 7.
  • the rod 4 and the T-profile 15 are supported by ball bearings 16, 17 at the end remote from the rod 7.
  • the printing chases A and B (or a chase B and an original) are 'laid with their longitudinal side-s beside each other.
  • the face of the original is located in the place of the printing surface of the printing form.
  • the chase B with or without form elements is disposed parallel with the ruler 15 by aligning the inside of the margins of the chase with the ruler.
  • the distance between the abutments 11 and 1-2 is adjusted to the distance be tween the margins of the chase B.
  • the transparent sheet 1 is adjusted relative to the original A by locating the guiding sleeve 6 against the abutment 12.
  • An aligning device for printing forms for use in fitting printing plates or blocks comprising a sheet of transparent material, a firs-t guide member having 2 opposite ends and to which said transparent sheet is slidably and detaehably connected, a second guide member to said second guide member and said connecting member.
  • said first guide member is a rod having a sleeve on the end thereof slidable on said second guide member, said sleeve being slidable on the second guide member
  • said connecting member is a rod on which said abutments are slidaible.
  • An aligning device as claimed in claim 2 in which said rod forming said first guide member has a crosspiece on the end thereof toward said sleeve, one end of said crosspiece being pivotally connected to said sleeve, and the other end of said crosspiece having a slot therein, and a bolt on said sleeve extending through said slot for adjusting the angular position of said rod relative to said sleeve and said second guide member.
