An injection system for injecting additive into a polymer transfer line is disclosed. The injection system can include an extruder having an inlet and an outlet. The injection system can further include a melt pump subsystem comprising at least a first melt pump and a second melt pump. Each melt pump of the first and second melt pumps can have an inlet and an outlet. The inlet of each of the first and second melt pumps can be in fluid communication with the outlet of the extruder. The first and second melt pumps can be arranged in parallel so that flow from the outlet of the extruder divides between the first melt pump and the second melt pump. The outlet of each of the first and second melt pumps can be in fluid communication with a polymer transfer line.

A winder for forming a yarn package can have a spindle axis. The winder can comprise a spindle that is configured to be rotatably driven about the spindle axis. A color probe can be positioned with respect to the spindle to measure a color value of yarn wound on the spindle.

Systems and methods for manufacturing colored product

A system for inspecting a tube can comprise a first image acquisition device that is configured to capture at least one image of the first end of the tube. A second image acquisition device can be configured to capture at least one image of at least a portion of the outer surface of the circumferential wall of the tube. A first conveyor can be configured to position the tube so that the first image acquisition device can capture the at least one image of the first end of the tube and the second image acquisition device can capture the at least one image of at least a portion of the circumferential wall of the tube. A computing device can be configured to determine, based on the at least one image from the first image acquisition device or the at least one image from the second image acquisition device, if the tube has a flaw.

Methods and devices for inspecting tubes

A system for making polymeric fibers can comprise a main extruder configured to receive a polymer feedstock composition. The main extruder can have an outlet in fluid communication with a transfer line configured to receive a polymer melt from the main extruder and transfer the polymer melt in a flow direction that is towards a spinneret. A side arm extruder assembly can be positioned along the transfer line between the main extruder and the spinneret. The side arm extruder assembly can comprise an outlet positioned within the transfer line to inject a colored polymer melt concentrate into the transfer line.
