Working assembly with a cooling system, for a machine for opening fibers, in particular a carding machine
First Claim
1. A working assembly for machines for opening fibers and/or preparation to carding, comprising:
- a hollow drum or cylinder, rotatable in operation, having a cylindrical wall at the ends of which there are coupled respective transverse header walls, and provided with a central longitudinal shaft;
clothing means, the external lateral surface of said cylindrical wall being provided with the clothing means intended to interact with the fibers being carded;
first and second support uprights which are fixed in operation, and adapted to support the ends of the shaft of the drum or cylinder for rotation about an axis;
a cooling system to cause cooling of the lateral cylindrical wall of the drum or cylinder, wherein;
the header walls are provided with respective openings;
the support uprights and the drum or cylinder are configured and coupled with each other such as to define at least one fluid path for a flow of a refrigerating fluid, which extends through the openings and inside of the drum or cylinder and is adapted to cause cooling of the lateral cylindrical wall thereof; and
at least one pumping device coupled with said fluid path and adapted to induce therein said flow of refrigerating fluid, wherein the support uprights are provided with a plurality of respective openings or passages communicating with the plurality of corresponding openings of the adjacent header walls.

Abstract
A working assembly (1) includes a rotatable hollow drum or cylinder (2) having a cylindrical wall (3) with ends having transverse header walls (4) with openings (16, 17), and with a longitudinal shaft (5). The external lateral surface of the cylindrical wall (3) has a clothing device intended to interact with the fibers being carded. First and second support uprights (6, 7) are fixed in operation, and adapted to support the ends of the shaft (5) of the drum or cylinder (2) for rotation about a preferably horizontal axis. The support uprights (6, 7) and the drum or cylinder (2) are configured and coupled with each other such as to define at least one fluid path for a flow of a refrigerating fluid, which extends through the openings (16, 17) and inside the drum or cylinder (2) and is adapted to cause cooling of the lateral cylindrical wall (3) thereof.
