Abstract
Paper machine felt for use in a papermaking machine, and especially at the press section, incorporates an adhesive which takes up the draw forces on the seam joint between the stepped surfaces of the ends of the belt when mated together to form a continuous belt.
Claims26
Paper machine felt (1) for utilization particularly in the press area of a paper machine with first and second free ends, one woven base (2) and a lap (10) that is needled onto the woven base (2), with the woven base (2) being equipped with at least two layers (3, 4) and the free ends of the paper machine felt (1) being equipped with step surfaces (11, 12) extending between at least two layers (3, 4) and connected with an adhesive (19), and with the paper machine felt (1) being equipped with a connecting element that transfers tensile force in closed condition, via which the ends are or can be connected, the adhesive (19) is the connecting element that transfers all tensile force.
A paper machine felt having first and second free ends, a woven base comprising first and second layers, and a lap that is needled onto the woven base, the first and second free ends of the felt including step surfaces extending between said first and second layers and an adhesive connecting said first free end to said second free end, wherein said adhesive is necessary to maintain the integrity of the connection between the first and second free ends.
A paper machine felt having connectable first and second free ends comprising:
- a woven base including first and second layers;
- a lap layer needled onto the woven base;
- step surfaces on the first and second free ends of the felt extending between said first and second layers;
- and
- an adhesive connecting said first free end to said second free end, whereby all tensile forces are transmitted from said first end to said second end via said adhesive.
A paper machine felt comprising:
- a woven base having first and second layers;
- a lap needled onto the woven base;
- a first free end including a step surface extending between said first and second layers;
- a second free end including a step surface extending between said first and second layers, said second free end being connected to said first free end with an adhesive and without the use of mechanical fasteners.
A paper machine felt comprising:
- a woven base having first and second layers;
- a lap needled onto the woven base;
- a first free end including a step surface extending between said first and second layers;
- a second free end including a step surface extending between said first and second layers, said second free end being connected to said first free end with an adhesive, wherein, but for the presence of said adhesive, said first end would separate from said second end.
