Definitions

  • a further object of the invention is to produce an illustrated record, the surface of which acts anti-statically. This object can be achieved in accordance with the invention by surrounding the illustration with a -transparent recording material in a greater thickness Ithan the one of the coated tone-foil.
  • the life of the record corresponds .to the duration of a tone record of multiple performance. The duration corresponds several times to the duration of a tone foil.
  • the tone groove is not applied to the outer layer under heat and simultaneous pressure as heretofore, but by pressing the heated recording material by cooling olf the pressing mold.
  • the method covered by this invention for Ithe production of pressed and sprayed records is characterized tha-t the illustration is not applied to the intermediate layer, but coated with a transparent outer layer. The latter completely shuts off the illustration from the outside and it adheres rmly and especially insolubly to the illustration. Furthermore, the groove is not applied to the outer layer as usual under previous heat and pressure, but only 3,247,298 Patented Apr. 19, 1966 by pressing the predheated material according to the cooling-olf method. f
  • the illustration as well as the recording material can be inserted before the application of the grooves between the image and the matrix in accordance with the pressing method by means of a pressing form having only a matrix with one groove.
  • T'he pressing method by means of a pressing form with matrixes having two grooves, lcalls for polyvinylchloridefoil of 0.75 mm. of thickness Ito be put in the form, the illustration to be covered with the same foil.
  • the pressing form is simply pressed slightly with the syntheticresin-press with a temperature brought up to 120 C. and pressed subsequently under cooling with a pressure of -tons for each 25 cm. of the record diameter.
  • the yform is opened. The material squeezed out at Ithe edges is removed and the record taken out of the form.
  • the illustration can be xed in the spraying form in such a way as to Ibe surrounded by the material sprayed in. However, it can also be stretched iu its middle in Ithe spraying form and surrounded by the recording material sprayed in ⁇ as far as the edge of the stretching apparatus.
  • a suitable synthetic resin or a mixture of same can be used.
  • Step #l shows the picture bearing carrier 2 which is placed between plastic foils 1
  • step 2 shows the .two foils with 'the carrier there between placed between a press mold inI dicated -by reference characters 3 and 4 of which the press mold part 3 has negative sound grooves on the surface 5.
  • 'Ilhe mold is closed as shown in step 3 and heat is then applied to the mold portions 3 and 4 to thus press the foils 1 to the carrier 2 with a slight press action.
  • the heat is transferred to the 4foils until the foils have reached plastic state. Then the heating is terminated Iand simultaneously -full press power is applied to the foils, step #4, by the press members 3 and 4 with fthe mold parts 3 and 4 cooled off and thus the composite sound record is produced which is embossed with the surface posi- Itive soun-d grooves on at least one side.
  • a method for lthe production of a composite sound record hearing sound grooves the record being produced from at least two transparent plastic foils with a picture bearing carrier being inserted between the foils Iand with the picture being visible from at least one side of the record, the method comprising placing the ⁇ foils and the intermediate picture bearing carrier into a press mold which has at least one press surface bearing surface negative sound grooves, closing the press mold so as .to slightly press together the foils and the picture bearing carrier, heating the mold so as to thereby transfer heat to the foils until the foils have reached a plastic state, terminating heating, and then simultaneously applying full press power to the foils and the picture bearing carrier while cooling off the mold, whereby a composite sound record is produced which is embossed with surface positive sound grooves on at least one side.
