The present invention describes various methods for manufacturing gel composite sheets using segmented fiber or foam reinforcements and gel precursors. Additionally, rigid panels manufactured from the resulting gel composites are also described. The gel composites are relatively flexible enough to be wound and when unwound, can be stretched flat and made into rigid panels using adhesives.

The present disclosure relates to a method for producing a decorative wall- or floor panel, having the method steps: • a) providing a melted polymer mass; • b) extruding the molten polymer mass through a nozzle; • c) finish-sizing the molten polymer mass to form a panel-like carrier material by means of an assembly of multiple rotatable rolls, wherein the individual rolls are disposed one above the other or one behind the other and each individual roll forms at least one finish-sizing nip with neighbouring rolls, through which nip the melted polymer mass is passed, and wherein the finishing nip heights can be variably adjusted by a horizontal and/or vertical movement of individual rolls during the production process; • d) applying a decor pattern that imitates a decor template to at least one sub-region of the at least partly finish-sized carrier material, and • e) applying a protective coating to at least one sub-region of the decor.

A textured film is provided which comprises nanocellulose. At least a first surface of the film comprises a patterned, textured surface formed by repeating protruding regions and at least one non-protruding region arranged between said protruding regions. A particular height difference between the protruding and non-protruding regions can give liquid repellent properties. Methods for making the textured film are also provided.

A system for ultrasonic bonding of elastic includes a rotating roll. The rotating roll has an exterior surface. A removable shell layer is attached to the external surface. The removable shell layer includes one or more patterned segments. The patterned segments include a shell channels formed through the removable shell layer to form a pattern.

A multipart underlayment having a cap sheet and base sheet combined to form a pocket for securely holding building materials and environmentally-friendly manufacturing method for manufacturing the same.

A method is provided for manufacturing flooring planks including a plastic base and an image plastic layer. The method includes a feeding step of feeding a plastic layer into oppositely rolling rollers; and a rolling step of hot rolling an embossing on the plastic layer. A feeding tension of the plastic layer is adjusted according to a longitudinal deviation between the embossing and the pattern in the rolling step. A device includes a first feeding device, an oppositely rolling rollers control device, a detecting device, and a tension controller disposed on the first feeding device. The method, the device and the long plastic layer with the embossing in register with the pattern processed use the method, implement the embossing rolled on the plastic layer in register with the pattern on the plastic layer and have high production efficiency, low cost and less energy consumption.

A method is provided for manufacturing flooring planks including a plastic base and an image plastic layer. The method includes a feeding step of feeding a layered raw material of a long decorative material to be rolled into oppositely rolling rollers; and a rolling step of hot rolling an embossing on the transparent plastic layer. A feeding tension of a printed plastic layer is adjusted according to a longitudinal deviation between the embossing and the pattern in the rolling step. The device includes a first feeding device, a second feeding device, the oppositely rolling rollers, a detecting device, and a tension controller disposed on the second feeding device. According to the long decorative material with the embossing in register with the pattern manufactured by the method, the embossing hot-rolled on the transparent plastic layer is in register with the pattern on the printed plastic layer.

A synthetic nonwoven fabric having bonded fibers forming channels surrounding unbonded fibers forming raised slip resistant spots. The fabric is made by extruding hot polymer through a spinneret die onto a moving belt to form a sheet of random fibers, which sheet undergoes a calendering process between a pair of heated rollers, one of which rollers having a plurality of cavities defined in its surface. The resulting fabric can be laminated and otherwise combined with other layers as desired to provide an end product having good slip resistant properties.
