The invention relates to a clothing () for a machine to manufacture or refine a fibrous web, in particular a paper, cardboard, or tissue web, comprising a substrate () and a grid structure () applied on the substrate (), on which the fibrous web is transported when the clothing () is used as intended, wherein the grid structure (') comprises a plurality of first elements (′), all of which aligned in a first direction, and a plurality of second elements (′), all of which aligned in a second direction, which is different from the first direction, wherein the first elements (′) penetrate the second elements (′), forming the grid structure (′), such that an underside of the first elements (′) facing the substrate () and an underside of the second elements (′) facing the substrate () are located in a common plane. In addition, the present invention relates to a method for producing such a clothing.

Laminated paper machine clothing

A paper machine clothing has a plurality of through-channels formed in a usable region. The through-channels extend through the substrate to connect the upper and lower sides. The through-channels are non-cylindrical with a cross-sectional area becoming smaller along a thickness direction of the substrate from the upper side to a middle region of the substrate. An upper rim of at least one of the plurality of through-channels directly contacts an upper rim of at least one other neighboring through-channel of the plurality of through-channels, wherein the upper rims of both neighboring through-channels have at least three common local maxima, including two outer common local maxima and one intermediate common local maximum that is located between the two outer common local maxima. There is also described a method of producing such a paper machine clothing.

Paper machine clothing and method of producing the same

A substrate of a paper machine clothing has a usable region formed with through-channels that are non-cylindrical with a cross-sectional area becoming smaller from an upper side to a middle region of the substrate. An upper rim of at least one of the through-channels directly contacts an upper rim of at least one neighboring through-channel and the upper rims have common local maximum. A sectional plane parallel to the thickness direction of the substrate defines an intersecting line with a sidewall of a neighboring through-channel. The intersecting line has a convexly shaped first portion, a concavely shaped second portion, and a third portion that is again convexly shaped going from the at least one common local maximum toward the middle region of the substrate. There is also described a method of producing such a paper machine clothing.

Paper machine clothing and method of producing the paper machine clothing

A paper machine clothing has a substrate with an upper side, a lower side, two lateral edges and a usable region between the two lateral edges. The usable region is formed with a plurality of through-channels extending through the substrate and connecting the upper side with the lower side. The through-channels are non-cylindrical with a cross sectional area becoming smaller when going in a thickness direction of the substrate from the upper side to a middle region of the substrate between the upper side and the lower side, wherein a shape of the cross sectional area of at least one through-channel, preferably of all through-channels, of the plurality of through-channels changes proceeding in the thickness direction of the substrate from the upper side to the lower side.

A method for producing an edge protector on a clothing for a machine producing or finishing a fibrous, paper, cardboard or tissue web, includes providing a clothing formed substantially from a woven fabric with crossing weft and warp threads and opposite side edges, applying a film strip onto a surface of one side edge and, immediately before bringing the film strip into contact with the clothing, surfaces of the film strip and the clothing facing each other are heated to slightly melt the surfaces. A pressing force exerted on the film strip applied to the surface of one of the side edges, results in the film strip penetrating at least partially into the woven fabric. That side edge of the clothing with the film strip is cooled, resulting in a stable, particularly integrally joined and form-locking connection between the film strip and the side edge of the clothing.

Edge protector for a papermachine clothing

The invention relates to a clothing () for a machine to manufacture or refine a fibrous web, in particular a paper, cardboard, or tissue web, comprising a substrate () and a grid structure () applied on the substrate (), on which the fibrous web is transported when the clothing () is used as intended, wherein the grid structure (') comprises a plurality of first elements (&#x2032;), all of which aligned in a first direction, and a plurality of second elements (&#x2032;), all of which aligned in a second direction, which is different from the first direction, wherein the first elements (&#x2032;) penetrate the second elements (&#x2032;), forming the grid structure (&#x2032;), such that an underside of the first elements (&#x2032;) facing the substrate () and an underside of the second elements (&#x2032;) facing the substrate () are located in a common plane. In addition, the present invention relates to a method for producing such a clothing.

A paper machine clothing draw-in device for drawing a paper machine clothing, in particular a drying screen, into a machine designed to produce and/or finish a material web, in particular a fibrous web, such as a paper, board or tissue web. The draw-in device includes a force-distributing element, which is designed to distribute a tensile force, which acts substantially at a point, substantially uniformly along a line. Here, the paper machine clothing draw-in device includes a plurality of such force-distributing elements, which are designed to become or to be connected to each other in normal use.

Paper machine clothing draw-in device and use of same

A paper machine clothing has a substrate with an upper side, a lower side, two lateral edges and a usable region between the two lateral edges. The usable region is formed with a multiplicity of through-channels that extend through the substrate from the upper side to the lower side. The through-channels are non-cylindrical with a cross sectional area becoming smaller when going in a thickness direction of the substrate from the upper side to a middle region of the substrate between the upper side and the lower side. An upper rim of at least one of the plurality of through-channels directly contacts an upper rim of at least one other neighboring through-channel of the plurality of through-channels. There is also described a method of producing such a paper machine clothing.
