Abstract: Systems and methods for laser trimming dental aligners include a model positioning system, an orientation determination system, and a laser trimming system. The model positioning system receives a physical dental model with a material thermoformed thereto. The dental model includes an orientation feature. The model positioning system moves the dental model to a position where the orientation feature is viewable by a camera. The camera captures an image of the orientation feature. The orientation determination system identifies an offset of the dental model by determining an actual orientation of the dental model based on the image of the orientation feature. The laser trimming system cuts the material from the dental model along a trim line while the fixture plate is moved about at least two axes relative to the laser trimming system.

Abstract: A coextrusion apparatus, a single-layer extrusion apparatus, a retrofit kit, as well as to a method for measuring a layer thickness, for producing a plastic film, and for retrofitting an extrusion apparatus. From the state of the art, it is known to add a detection agent in the form of a fluorescent granulate into the starting material at the extruder, in order to be able to measure the layer thickness of the layer in the film composite produced from this starting material. However, it is proposed to feed in a detection agent only beyond the extruder. This leads to a clearly shorter running time of the detection agent through the system and thereby to clearly faster measurability of changes in the production parameters.

Abstract: This process for manufacturing a carbon-fiber precursor acrylic fiber bundle and this steam drawing apparatus are characterized in that the drawing of an acrylic fiber bundle with a pressured-steam drawing apparatus is conducted by: opening an acrylic fiber bundle by blowing a fluid thereto; supplying humidifying steam to the opened acrylic fiber bundle at a fiber temperature of 80 to 130° C. to adjust the water content of the fiber bundle to 3 to 7%; and thereafter drawing the resulting acrylic fiber bundle in a pressurized-steam atmosphere. Thus, the present invention can prevent the breaking of a single fiber, the fluffing of the fiber bundle, and the breaking of the whole of the fiber bundle, though such defects are susceptible to occurring in a case where an acrylic fiber bundle is drawn by steam drawing at a high draw ratio, at a higher speed, or into a fiber having a small denier.
