Abstract
A multifunction apparatus for processing webs of fibrous and/or pliable material includes a tubular sleeve of an elastic material, a pair of discs supporting the tubular sleeve, a fixed shaft on which the discs are mounted such that their axis is inclinable to the axis of the sleeve, the end portions of the shaft extending beyond said discs, and a system moving the disc/sleeve system relative to the shaft.
Claims14
A multifunction apparatus for processing a fibrous web comprising:
- a tubular sleeve of an elastic material;
- a pair of discs for supporting said tubular sleeve, such to form a disc/sleeve system;
- a fixed shaft on which said discs are mounted such that an axis of the disks discs is inclinable in relation to an axis of said sleeve, end portions of said shaft extending beyond said discs;
- and
- a moving system configured to move the disc/sleeve system relative to said fixed shaft,
- wherein the tubular sleeve is permeable to fluids.
