Abstract
Abstract 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.

Claim 1
Independent Claim
331 words
An apparatus for continuously making a mixture of viscous material with solid material, which comprises; first and second rotatable members supported in position for rotation in the opposite directions with respect to each other and spaced a predetermined distance from each other to define a mixing gap therebetween; first supply means for supplying the viscous material and for generating zones of cascading flow of said viscous material, said zones of cascading flow of said viscous material being respectively downwardly oriented towards said first and second rotatable members, said cascading flow of said viscous material in said zones forming a viscous layer around said first and second rotatable members, said viscous layers on said first and second rotatable members adjoining to each other and subsequently entering said mixing gap as said first and second rotatable members are rotated in the opposite directions to each other; second supply means for supplying the solid material onto said viscous layers, said solid material after having been supplied onto said viscous layers being dragged into said mixing gap during rotation of said first and second rotatable members to mix with said viscous material as it pass through said mixing gap; and third and fourth rotatable members supported in position below said first and second rotatable members for rotation in the opposite directions to each other at a higher speed than any of said first and second rotatable members, said third and fourth rotatable members being respectively rotated in the same direction as said first and second rotatable members and spaced a predetermined distance from said respective first and second rotatable members, said third and fourth rotatable members acting to remove the viscous mixture, which has emerged from said mixing gap sticking in part to said first rotatable member and in part to said second rotatable member, off from said first and second rotatable members, said mixture which has been removed from said first and second rotatable members subsequently falling downwards by gravity and being then collected.
Claim 2

An apparatus for continuously making a mixture of viscous material with solid material, which comprises; first and second rotatable members supported in position for rotation in the opposite directions with respect to each other and spaced a predetermined distance from each other to define a mixing gap therebetween; first supply means for supplying the viscous material and for generating zones of cascading flow of said viscous material, said zones of cascading flow of said viscous material being respectively downwardly oriented towards said first and second rotatable members, said cascading flow of said viscous material in said zones forming a viscous layer around said first and second rotatable members, said viscous layers on said first and second rotatable members adjoining to each other and subsequently entering said mixing gap as said first and second rotatable members are rotated in the opposite directions to each other; second supply means for supplying the solid material onto said viscous layers, said solid material after having been supplied onto said viscous layers being dragged into said mixing gap during rotation of said first and second rotatable members to mix with said viscous material as it pass through said mixing gap; and third and fourth rotatable members supported in position below said first and second rotatable members for rotation in the opposite directions to each other at a higher speed than any of said first and second rotatable members, said third and fourth rotatable members being respectively rotated in the same direction as said first and second rotatable members and spaced a predetermined distance from said respective first and second rotatable members, said third and fourth rotatable members acting to remove the viscous mixture, which has emerged from said mixing gap sticking in part to said first rotatable member and in part to said second rotatable member, off from said first and second rotatable members, said mixture which has been removed from said first and second rotatable members subsequently falling downwards by gravity and being then collected.
Claim 3
Dependent Claim
18 words
An apparatus as claimed in claim 1, wherein said first and second rotatable members comprise cylindrical rolls, respectively.
Claim 4
Dependent Claim
38 words
An apparatus as claimed in claim 1, wherein said first and second rotatable members comprise endless belts which are substantially vertically extending in parallel relation to each other, the adjacent runs of said belts defining said mixing gap.
Claim 5
Dependent Claim
37 words
An apparatus as claimed in claim 1, wherein said first and second rotatable members comprise endless belts which are substantially horizontally extending in line with each other, the adjacent ends of said belts defining said mixing gap.
Claim 6
Dependent Claim
41 words
An apparatus as claimed in claim 1, further comprising a packaging unit for packing the mixture, which has been removed off from said first and second rotatable member and subsequently fallen downwards, between a pair of carrier sheets of synthetic resin.
Claim 7
Dependent Claim
18 words
An apparatus as claimed in claim 5, wherein said first and second rotatable members comprise cylindrical rolls, respectively.
Claim 8
Dependent Claim
