Device for making recording disc cartridge

Claim 1

A device for making a magnetic recording disc cartridge having a cover jacket in the form of an enclosure with a drive shaft insertion hole and a recording heat access hole defined therein and a magnetic recording disc which is rotatably enclosed in the enclosure, said cover jacket being composed of a cover sheet of a generally elongated rectangular shape with a liner laid on the surface of the cover sheet, said jacket being formed by folding the cover sheet with a liner along a line crossing in a direction of the short side of the cover sheet in such a manner that both portions of the liner positioned on both sides of the folded liner are opposed to each other in the enclosure, said device comprising; a feed table for placing the cover sheet with the liner thereon; first adhering means having a plurality of heating chips for adhering said liner to the cover sheet by heat melting adhesion, said heating chips being vertically movably disposed above the feed table; first transferring means for transferring the cover sheet with the liner from an initial position remote from the first adhering means on the feed table to such a position that a front peripheral edge portion of the liner is placed below the heating chips of the first adhering means; means for reciprocably moving the heating chips in a vertical direction, whereby said cover sheet with the liner is transferred to such a position that the front peripheral edge portion of the liner is placed below the heating chips of the first adhering means by said first transferring means and in turn the heating chips of the first adhering means are lowered to contact on the liner from above to preliminarily adhere the liner to the cover sheet by a plurality of spots on the front peripheral edge thereof; second adhering means for adhering the liner to the cover sheet by heat melting adhesion around the respective patterns of the drive shaft insertion hole and the recording head access hole, said second adhering means including a plurality of heating chips for adhering the liner on the cover sheet on a rear peripheral edge of the liner, said adhering of the respective patterns of the drive shaft insertion hole and the recording head access hole and the adhering of the rear peripheral edge of the liner on the cover being performed simultaneously; second transferring means for transferring the cover sheet with the liner to a position below the second adhering means after said preliminary adhering is perfected; third adhering means for adhering the liner to the cover sheet by heat melting adhesion over a plurality of predetermined linear patterns on the liner; and third transferring means for transferring the cover sheet with the liner from the second adhering means to the third adhering means.

Claim 2

A device for making a magnetic recording disc cartridge having a cover jacket in the form of an enclosure with a drive shaft insertion hole and a recording heat access hole defined therein and a magnetic recording disc which is rotatably enclosed in the enclosure, said cover jacket being composed of a cover sheet of a generally elongated rectangular shape with a liner laid on the surface of the cover sheet, said jacket being formed by folding the cover sheet with a liner along a line crossing in a direction of the short side of the cover sheet in such a manner that both portions of the liner positioned on both sides of the folded liner are opposed to each other in the enclosure, said device comprising; a feed table for placing the cover sheet with the liner thereon; first adhering means having a plurality of heating chips for adhering said liner to the cover sheet by heat melting adhesion, said heating chips being vertically movably disposed above the feed table; first transferring means for transferring the cover sheet with the liner from an initial position remote from the first adhering means on the feed table to such a position that a front peripheral edge portion of the liner is placed below the heating chips of the first adhering means; means for reciprocably moving the heating chips in a vertical direction, whereby said cover sheet with the liner is transferred to such a position that the front peripheral edge portion of the liner is placed below the heating chips of the first adhering means by said first transferring means and in turn the heating chips of the first adhering means are lowered to contact on the liner from above to preliminarily adhere the liner to the cover sheet by a plurality of spots on the front peripheral edge thereof; second adhering means for adhering the liner to the cover sheet by heat melting adhesion around the respective patterns of the drive shaft insertion hole and the recording head access hole, said second adhering means including a plurality of heating chips for adhering the liner on the cover sheet on a rear peripheral edge of the liner, said adhering of the respective patterns of the drive shaft insertion hole and the recording head access hole and the adhering of the rear peripheral edge of the liner on the cover being performed simultaneously; second transferring means for transferring the cover sheet with the liner to a position below the second adhering means after said preliminary adhering is perfected; third adhering means for adhering the liner to the cover sheet by heat melting adhesion over a plurality of predetermined linear patterns on the liner; and third transferring means for transferring the cover sheet with the liner from the second adhering means to the third adhering means.
