Definitions

  • the present invention relates to packaging of compact discs and the like into relative envelopes.
  • Compact discs can be packaged not only in the traditional cases formed by two shells made of a plastic material, but also inserted into envelopes of different shape made from sheet material like paper or cardboard.
  • these envelopes are obtained from a sheet of cardboard folded along a median line, so as to form two surfaces facing each other, that are joined along two sides adjacent to the fold side by gluing of respective flaps.
  • the side of the envelopes opposite to the fold side is open.
  • the envelopes are provided with a closing strips, extending from one surface along the open side, and can be folded over the other surface to close the envelope opening.
  • These closing strips may have different shapes and dimensions; in particular, they may extend on an area equal to the envelopes surfaces.
  • one of the envelope surfaces has an aperture, generally circular, covered with a sheet of a transparent material, so that a corresponding face of the compact disc contained in the envelope can be seen from outside.
  • the compact discs are usually accompanied by respective cover sheets, sometimes book-like made, containing information about the disc contents and the like.
  • Packaging of the compact discs inside the envelopes of different shape is difficult because of little versatility of the packaging lines.
  • the object of the present invention is to propose a versatile machine for packaging compact discs into relative envelopes, with the possibility of using envelopes of different shapes without any need of part substitution or size change over.
  • Another object of the present invention is to propose a machine, which requires only rapid adjustment of the envelopes magazine walls, when the envelope shape is to be changed.
  • a further object of the present invention is to propose a machine, with which compact discs can be packed together with a cover sheet situated under or over the compact disc, into the envelopes.
  • t includes: a withdrawing unit for withdrawing single envelopes from a magazine and for transferring the withdrawn envelopes to an envelope conveying lines, with the front edges located in alignment with a reference axis defined along said conveying line, clamping means for keeping said envelopes on said conveying line during forward motion thereof; handling means for releasing single compact discs, said handling means oeing adapted to join up said compact discs and respective sheets taken out from a sheet magazine and insert said compact discs along with associated sheets into related envelopes kept dwelling on said conveying line .
  • FIG. 3 shows a plan view of clamping means aimed at keeping a single envelope during movement along the conveying line;
