Apparatus and process for manufacture of variegated soap bars

Claim 2

Apparatus for production of variegated soap bars, said apparatus comprising: (a) means to form soap noodles of one color; (b) means to form soap noodles of a second color; (c) means to receive noodles from means (a) and means (b) and to form side-by-side streams of noodles with each stream of the side-by-side streams being of noodles of one of the colors; (d) plodder means having a rotatable worm to process the noodles into a variegated soap log; (e) means for forming the soap log into variegated soap bars; (f) means for receiving noodles from the means (c) and providing at least one bed of noodles for choke feeding of the plodder means and having outlet means providing communication essentially only with a portion of the worm of the plodder means which turns downwardly on rotation of such worm.

Claim 3

Apparatus as recited in claim 1 wherein means (f) provides a single bed of noodles for choke feeding of the plodder means and in which the outlet means in the means (f) has an opening with a dimension in the cross machine direction in respect to the plodder means of no more than about 1.1 times the radial dimension of the worm.

Claim 4

Apparatus as recited in claim 1 in which the outlet means in the means (f) has an opening in the form of a right parallelogram having a dimension in the machine direction in respect to the plodder means ranging from about one-half the flight distance to about twice the flight distance and a dimension in the cross machine direction in respect to the plodder means ranging from about one-half the radial dimension of the worm to about 1.1 times the radial dimension of the worm.

Claim 5

Apparatus as recited in claim 3 in which the outlet means of the means (f) is positioned and the opening of said outlet means is dimensioned so as to provide a feed stream into the plodder means having a horizontal cross section which is rectangular and has a dimension in the machine direction of the plodder means of one times the flight distance and a dimension in the cross machine direction of the plodder means equal to the radial dimension of the worm.

Claim 6

Apparatus as recited in claim 1 in which the means (f) includes divider means which extends in a longitudinal direction to form side-by-side channels into the plodder means with one of the channels functioning to receive noodles from means (a) and the other of the channels functioning to receive noodles from means (b).

Claim 7

Process for manufacture of variegated soap bars, said process comprising: (a) providing a soap mass of one color; (b) providing a soap mass of a second color; (c) plodding the soap mass of the one color to compact and extrude the same and form noodles; (d) plodding the soap mass of the second color to compact and extrude the same and form noodles; (e) directing the noodles to form side-by-side streams to provide a separate bed of noodles from each respective stream; (f) feeding noodles downwardly from each bed into a plodding means while restricting lateral and longitudinal motion of noodles in each bed by use of a hopper means which choke feeds said noodles onto essentially only the downwardly-turning portion of the worm of said plodding means; (g) plodding the noodles fed downwardly from each bed to compact and extrude the same and form a variegated soap log; (h) forming the log into variegated soap bars.

Claim 8

Process for manufacture of variegated soap bars, said process comprising: (a) providing a soap mass of one color; (b) providing a soap mass of a second color; (c) plodding the soap mass of the one color to compact and extrude the same and form noodles; (d) plodding the soap mass of the second color to compact and extrude the same and form noodles; (e) directing the noodles to form side-by-side streams to provide a separate bed of noodles from each respective stream; (f) feeding noodles downwardly from each bed into a plodding means while restricting lateral and longitudinal motion of noodles in each bed by use of a hopper means which choke feeds said noodles onto essentially only the downwardly-turning portion of the worm of said plodding means; (g) plodding the noodles fed downwardly from each bed to compact and extrude the same and form a variegated soap log; (h) forming the log into variegated soap bars.
