Abstract
Abstract A continuous press, especially for squeezing fruits with two endless pressing belts and a plurality of rotatable pressing rollers, each cooperating with two supporting rollers thereunder on either side, arranged with a small number in a first train and a greater number in a main train on a supporting frame, said supporting frame being supported between the first and main train in such a way that it can pivot about a horizontal axis, with a pressing member being provided in order to exert (almost independently of the position of the supporting frame) a rather great force on the free end of the main train part of the supporting frame.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
176 words
A continuous press, especially for squeezing fruits, comprising two endless pressing belts which can be driven in a longitudinal direction and almost parallelly to each other in a pressing area, of which belts at least one being permeable for liquids, while the pressing area comprises a plurality of pressing rollers, each cooperating with two supporting rollers on either side thereof and thereunder and which are stationary in that vertical direction, but can rotate under the pressing belts comprising a rather small number of the pressing rollers arranged in a first train and a rather great number of pressing rollers, arranged in a main train on a supporting frame in which the pressing rollers are supported in such a way that they are individually adjustable for height, said supporting frame being supported between the first and main train in such a way that it can pivot about a horizontal axis and a pressing member being provided in order to exert a rather great force on the free end of the main train part of the supporting frame.
Claim 2
Dependent Claim
176 words

Claim 3
Dependent Claim
69 words
A device according to claim 1, wherein the pressing member comprises a two-armed lever which via a horizontal pivot shaft in the proximity of the free end of the main train part of the supporting frame acts thereon, while the upper side of the short arm of this lever cooperates with a stationary knife profile and the longer arm of the lever extends substantially parallel to the supporting frame.
Claim 4
Dependent Claim
36 words
A device according to claim 2, wherein means like weights are arranged in the vicinity of the end of the longer lever arm, which freely extends above the supporting frame, in order to exert pressure thereon.
Claim 5
Dependent Claim
40 words
A device according to claim 1, wherein at least the lower pressing belt is made of plastics and metal, the plastics wires extending in the longitudinal direction of the belt and the stainless steel wires extending in the transverse direction.
