摘要： A method and an extrusion- or pultrusion device (1) for forming a profile product (2) made from a material in a production direction (Y), said device comprising:



a rotating die (3), extending in a radial (R) direction and a width direction (X), having two opposite first and second side walls (5, 6) and an outer circumferential surface (4) extending in the width direction (X) there between, wherein the rotating die (3) comprises a first side portion (23) in connection to the first side wall (5) and a second side portion (25) in connection to the second side wall (6) and a mid-portion (22) extending between the first and second side portions (23, 25), and
a profile definition zone (7) having a longitudinal direction (Y) coinciding with the production direction (Y), a height direction (Z) and a width direction (X) being perpendicular to the height direction (Z), comprising a through channel (8) comprising a first channel section (9) followed by a second channel section (10) downstream the first channel section (9) with reference to the production direction,

wherein the rotating die (3) is rotatable about an axis extending across the production direction (Y) and arranged to allow the outer circumferential surface (4) to, while the rotating die (3) rotates, exert a pressure onto a surface of the material when fed through the profile definition zone (7).

摘要： A method of manufacturing a polymer film includes melting a resin, extruding the melted resin through a die to produce a polymer film, shaping the polymer film, cooling the polymer film, capturing an image of a test pattern through the polymer film, calculating a modulation transfer function value from the image, and adjusting a process parameter of the melting, the extruding, the shaping, or the cooling based on the calculated modulation transfer function value.

摘要： 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.

摘要： A method of manufacturing a tire tread includes extruding a rubber strip and conveying the rubber strip through an opening of a roller die. The opening is defined by an upper die and a lower die, wherein the upper die and lower die contact the rubber strip and define a cross-section of the rubber strip as the rubber strip is conveyed through the opening. The method also includes adjusting a distance between the upper die and the lower die as the rubber strip is conveyed through the opening. The method further includes applying the rubber strip from the roller die onto a receptacle that rotates about a receptacle axis. The method also includes translating the roller die in a first direction parallel to the receptacle axis while applying the rubber strip, thereby forming a spiral of the rubber strip about the receptacle.

摘要： A rubber strip manufacturing method that includes a step of extruding a rubber from an extrusion orifice of an extruder includes: a step of forming a long rubber member by extruding the rubber from the extrusion orifice that is circular; and a step of forming a rubber strip by passing the long rubber member through a gap between a pair of rotating rollers. The gap has a shape that is the widest in a central portion in a direction parallel to rotation axes of the rollers and that narrows as a distance from the central portion increases.

摘要： This disclosure describes devices, systems, and methods related to a compound film. An exemplary compound film includes a first layer including a first polymer composition including polyurethane and a second layer including a second polymer composition removably coupled to the first layer. The compound film further includes light switchable adhesive coupled to the second layer and configured to transition from a first state to a second state, the light switchable adhesive has a first peel strength in the first state that is greater than a second peel strength of the light switchable adhesive in the second state. A third peel strength between the first layer and the second layer is less than the second peel strength between the light switchable adhesive in the first state and a bond site.

摘要： A method for producing thermally crosslinkable polymers in a planetary roller extruder is presented. The planetary roller extruder has a filling part and a compounding part made of a roller cylinder region that comprises at least two, preferably at least three coupled roller cylinders, planetary spindles of which are driven by a common central spindle. The polymers are supplied in a plasticized state. The filling part is supplied with a vacuum. The flow temperatures of the central spindle and the at least two roller cylinders under a vacuum are set such that the polymers to be degassed remain in the plasticized state. One or more liquids, such as thermal crosslinkers, crosslinking accelerators, dye solutions, or dye dispersions, are metered to the plasticized polymers downstream of the vacuum degassing, preferably in a continuous manner. Finally, the resulting mixture is directly supplied to a coating assembly.

摘要： Provided is a molding hook and loop fastener, in which a barrier erected near left and right side edges of a substrate includes at least two rows of vertical wall arrays, and the vertical wall array positioned on the outermost side includes a plurality of gaps provided at a predetermined pitch in a length direction. At least two of the gaps are provided on the vertical wall array positioned on the outermost side with respect to a region between the engaging elements adjacent in the length direction of the substrate. Due to this, in the molding hook and loop fastener, an outer side and an inner side of the barrier can be divided by the vertical wall array, and flexibility of the molding hook and loop fastener can be improved.
