Abstract
Abstract The present portioning device has a metering chamber and a compression chamber in which the material metered in the metering chamber is compressed. An intermediate chamber having a volume larger than the metering chamber is arranged for receiving the yet uncompressed but metered portion to locate such portion for compressing transfer into the compression chamber.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
102 words
A device for portioning and compressing material, comprising a metering chamber having an inlet and an outlet, an intermediate chamber connected to receive material from said outlet and having a volume at least as great as the volume of said metering chamber, a compression chamber connected to receive material from said intermediate chamber, a compression piston mounted to reciprocally extend through said intermediate chamber into said compression chamber and having a material compressing position in which it blocks said outlet and a further position permitting transfer of material from said outlet through said intermediate chamber, and means for selectively blocking said inlet.
Claim 2
Independent Claim
102 words
A device for portioning and compressing material, comprising a metering chamber having an inlet and an outlet, an intermediate chamber connected to receive material from said outlet and having a volume at least as great as the volume of said metering chamber, a compression chamber connected to receive material from said intermediate chamber, a compression piston mounted to reciprocally extend through said intermediate chamber into said compression chamber and having a material compressing position in which it blocks said outlet and a further position permitting transfer of material from said outlet through said intermediate chamber, and means for selectively blocking said inlet.
Claim 3
Dependent Claim
29 words
The device of claim 1, wherein said means for blocking said inlet comprises rotary knife means rotatable in a plane parallel to the direction of movement of said piston.
Claim 4
Dependent Claim
132 words
In a portioning device for a material compressing apparatus of the type having a metering chamber with a given volume for receiving and metering a predetermined amount of material to be compressed, the metering chamber having an inlet and an outlet, and a compression chamber for receiving metered material from said outlet; the improvement comprising an intermediate chamber located between said compression chamber and said outlet of said metering chamber, the volume of said metering chamber being greater than the volume of said compression chamber, the volume of said intermediate chamber being at least as great as the volume of said metering chamber, said portioning device further comprising movable cutting means at said inlet of said metering chamber for severing the material and for temporarily closing said inlet of the metering chamber.
Claim 5
Dependent Claim
132 words
In a portioning device for a material compressing apparatus of the type having a metering chamber with a given volume for receiving and metering a predetermined amount of material to be compressed, the metering chamber having an inlet and an outlet, and a compression chamber for receiving metered material from said outlet; the improvement comprising an intermediate chamber located between said compression chamber and said outlet of said metering chamber, the volume of said metering chamber being greater than the volume of said compression chamber, the volume of said intermediate chamber being at least as great as the volume of said metering chamber, said portioning device further comprising movable cutting means at said inlet of said metering chamber for severing the material and for temporarily closing said inlet of the metering chamber.
Claim 6
Dependent Claim
25 words
The device according to claim 3, further comprising reciprocable means for moving said predetermined amount of material from said intermediate chamber to said compression chamber.
Claim 7
Dependent Claim
45 words
The device according to claim 4, wherein said intermediate chamber and said compression chamber are arranged in alignment With each other and said reciprocable means is a piston, whereby adjacent sectional areas of the intermediate chamber and of the compression chamber correspond to each other.
Claim 8
Dependent Claim
50 words
The device according to claim 5, wherein said piston is reciprocable between a first end position outside said intermediate chamber and a second compressing end position whereby the piston in its second end position separates said intermediate chamber from said metering chamber by closing the outlet of the metering chamber.
