Abstract: Recycling devices for producing additive manufacturing filament from received materials including objects to be recycled, discarded objects, obsolete objects, and the like. A recycling device may include a material processing system an extrusion mechanism and a spooling assembly. The material processing system receives material, reduces the size of the received material via a material size reducer and actively pushes the material through at least a portion of the device. The extrusion mechanism produces filament from the material and the spooling assembly loads the filament onto a spool for later use. The spooling assembly may include detachable elements configured to interface with and supply filament to an additive manufacturing device. Depending on configuration, recycling devices may create filament from plastic, metal, in-situ material, or a combination thereof.

Abstract: A winding head of a cheese-producing textile machine, having a device for the accurate determination of the length of yarn traveling through a measuring head (7), and having an evaluating device for accumulating the yarn lengths that have passed. The winding head has a device for determining yarn length portions which are removed in the course of a yarn connecting process. The evaluation device is adapted to subtract the removed yarn lengths from the total length of the yarn (2) which has passed through the measuring head.

Abstract: A yarn breakage position detecting device and method of detecting a yarn breakage position involves a running yarn tension detector arranged at a reference position and that outputs a tension signal by which occurrence of yarn breakage is detected, and passage of the end of a broken yarn through the reference position is then calculated based on the time period from occurrence of yarn breakage to passage of the broken yarn end through the reference position. The yarn breakage time is stored as a time at which the tension signal becomes a peak value and/or a time at which the tension signal begins to decrease below a steady state tension value. The time when the yarn passes through the reference position is stored as a time at which the tension signal becomes lower than a lower limit value and/or a time at which natural oscillation begins.
