(57) A pneumatically-operated press is particularly for extracting juice from grapes and
other fruit.
The press includes a rotatable horizontal drum 3 sub-divided by membranes 10, 11 into
a pressing space and two air spaces. The pressing space is defined by the two membranes
and a slotted wall 22 of the drum.
The membranes 10,11 are each secured along their longitudinal edges to the circumferential
wall of the drum at one edge 12, 13 and to a support 4 spaced radially inwardly of
the drum wall at the other edge.
The support 4 is triangular in cross-section with the edges of the membranes 10, 11
secured at the apex of the triangle by connecting strips 8, 9.
