Aspects of the present invention relate to a tire tread production line and a method for manufacturing a tire tread. The production line comprises a coextruder, a THz sensor and a controller operatively connected to the coextruder and to the THz sensor. The THz sensor is configured to irradiate the multi-layer tire tread extrudate with THz electromagnetic radiation, and receive a response of the multi-layer tire tread extrudate to the THz electromagnetic radiation. The controller is configured to operate the coextruder based on the response of the multi-layer tire tread extrudate to the THz electromagnetic radiation.

An extrusion nozzle for making tubular preforms has a mandrel extending along a vertical axis, an annular and stationary nozzle body spacedly radially surrounding the mandrel, and a holding ring having an upper end axially slidable in the nozzle body, braced axially downwardly against the nozzle body, and having a lower end spaced radially inward from shiftable limitedly radially relative to the nozzle body. A nozzle ring has an upper end axially slidable in the holding ring, is braced axially downwardly against the nozzle body, and has a radially deflectable lower end forming an annular extrusion gap with the mandrel. A first positioner engages the lower end of nozzle ring and is operable to radially deflect this lower end. A second positioner engages radially with the lower end of the holding ring or with the nozzle ring for radially deflecting same.

The present invention provides a method for improving visibility of an image display device which is capable of providing an image display device excellent in anti-reflection properties and bright-field contrast even using an optical layered body including a light-transmitting substrate having in-plane birefringence, such as a polyester film. The method of the present invention is a method for improving visibility of an image display device that has an optical layered body including a light-transmitting substrate having in-plane birefringence and an optical functional layer disposed on one surface of the substrate. The method includes the step of disposing the optical layered body such that the slow axis showing a greater refractive index of the light-transmitting substrate is in parallel with the vertical direction of a display screen of the image display device.

The invention relates to a method for automatically regulating the size of a nozzle discharge slot of a nozzle assembly, wherein the nozzle assembly comprises a first and a second nozzle lip and a nozzle discharge slot arranged between the nozzle lips for setting in a controlled manner a thickness profile of a conveyable melt. A plurality of adjusting elements, in particular a plurality of adjusting pins, coupled to a respective thermoelement, is arranged on the first nozzle lip, the thermoelements being controllable by the regulation in such a way that the slot can be adjusted by the action of a mechanical force from the respective adjusting element on the first nozzle lip, as a result of the expansion or contraction of the thermoelements. At an initial operation of the nozzle assembly for conveying the melt, the adjusting elements for subsequent regulation of the slot size are set uniquely free from play as the initial setting. The invention further relates to a control and/or regulation system.

The invention relates to an adjusting device (10) for controlling a discharge thickness (AD) of a nozzle discharge slot (110) of a flat film machine (100), comprising a plurality of adjusting bolts (20) for carrying out an adjusting movement for changing the discharge thickness (AD), wherein the adjusting bolts (20) comprise an adjusting region (SB) between a closing end position (SE) and an opening end position (OE), wherein further starting from the opening end position (OE), the adjusting region (SB) comprises a basic stroke path (BH) for a basic adjustment of the discharge thickness (AD) and, starting from the closing end position (SE), comprises a process stroke path (PH) for process controlling of the discharge thickness (AD).

The invention relates to a method for controlling a thickness profile (DP) of a film track (FB) along a transverse direction (QR) by means of a plurality of adjusting means (120) for adjusting a slot opening (112) of a discharge nozzle (110) of the flat film machine (100), comprising the following steps: acquiring a thickness profile (DP) along the transverse direction (QR) of the film track (FB) transverse to a production direction (PR) of the flat film machine (100), comparing at least a partial section of the acquired thickness profile (DP) with a preset profile (VP), determining at least one local profile deviation (PA) in a deviation section (AA) as a result of the comparison, generating at least one controlling intervention for the adjustment of at least one adjusting means (120) in an intervention section (EA) different from the deviation section (AA).
