An apparatus for compressing a web W of fibrous material where the apparatus includes a first surface (3) movable in one direction and a second surface (5) movable in an opposite direction at a speed slower than the speed of movement of the first surface. A confining means (7) having an apex (10) extends between the surfaces. A stuffing chamber (13) is formed between the two surfaces and the confining means. Movement of the first surface feeds a web of material into the stuffing chamber and movement of the second surface moves compressed material out of the chamber. A method of compressing a web W of fibrous material where said material is forced into a stuffing chamber (13) formed between a confining means (7) having an apex (10) and two surfaces (3 and 5). A web of material is fed into the stuffing chamber by moving one of the surfaces in one direction at a particular speed. Compressed material is removed from the stuffing chamber by moving the second surface in a direction opposite to that of the first surface and at a slower speed than that of movement of the first surface.
A method for the compressive treatment of a fibrous thread interlaced web material wherein said material is forced into a stuffing chamber formed by a space between a first movable uninterrupted cylindrical surface and a second movable uninterrupted surface and a smooth arcuate apex of a confining means extending in part between and spaced from the first and second surfaces with the confining means having a concave confining surface connecting with said apex spaced from and opposite the first surface and subtending an angle therewith, comprising the step of moving the first surface at a first rate of speed in a first direction to move said material between it and said confining surface towards and into said stuffing chamber, and the step of moving the second surface in a second direction opposite to said first direction at a second rate of speed slower than said first rate of speed to move said material in said second direction around said apex and out of said stuffing chamber.
An apparatus for the compressive treatment of a fibrous thread interlaced material where the apparatus comprises a first movable uninterrupted cylindrical surface, means for moving the first movable surface in a first direction at a first rate of speed, a second movable uninterrupted surface spaced from the first movable surface, means for moving the second movable surface in a second direction opposite to said first direction at a second speed rate of speed slower than said first rate of speed and a confining means spaced from the first and second movable surfaces having a smooth arcuate apex extending between and towards the first and second surfaces to form a stuffing chamber therewith into which material is adapted to be moved by the first movable surface and from which material is adapted to be moved by the second movable surface around the apex, said confining means including a concave confining surface connecting with said apex spaced from and opposite the first movable cylindrical surface and subtending an angle with said first movable cylindrical surface.
An apparatus for the compressive treatment of a fibrous material where the apparatus comprises a first roll, means for rotating said first roll in a first direction at a fixed rate of speed, a second roll spaced from said first roll, means for rotating said second roll in the same direction as said first roll at a second rate of speed slower than said first rate of speed, a gull-shaped body having two wings spaced from said rolls wherein the spacing between the second roll and one wing of the gull-shaped body is greater than the spacing between the first roll and the other wing of the gull-shaped body and wherein the juncture between the two wings comprises an apex extending between and towards said rolls to form a stuffing chamber therewith into which material is adapted to be moved by said first roll, and means for varying the angle between the wings of the gull-shaped body whereby the spacing between the wings and the first and second rolls may be varied.
