A mold assembly for use in a packaging machine for making a blistered package, which forms a plurality of blisters in a web of thermoplastic resin film forming a part of the blistered package. The mold assembly comprises a preforming structural body formed with a plurality of preforming molds and a finishing structural body formed with the corresponding number of finishing molds arranged in the same pattern as the preforming molds. The thermoplastic resin web is first subjected to a preforming process with the preforming structural body and then to a final forming process with the finishing structural body thereby to avoid excessive and quick reduction of the wall thickness which may otherwise be observable in any of the finally formed blisters. A method for this purpose is also disclosed.

Mold assembly for use in packaging machine

An apparatus for continuously making a mixture of viscous material with solid material, which comprises a pair of spaced mixing rolls for dragging the viscous material and the solid material into a gap between the mixing rolls to permit the materials to be mixed together. A pair of removal rolls, each rotatable at a higher speed than any of the mixing rolls, are provided below the mixing rolls respectively spaced a predetermined distance from the associated mixing rolls for removing layers of the mixture sticking in part to one mixing roll and in part to the other mixing roll, off from the mixing rolls. The mixture removed from the mixing rolls by the removal rolls falls downwardly onto a packaging process wherein the mixture is packed between a pair of carrier sheets of synthetic resin material.
