| Description | Model LBS-100 Lab Scale Bicomponent Extruder Fed Spinning Machine. The machine is designed for laboratory use to make small amounts of bicomponent fiber from small amounts of polymer. It requires as little as 10 grams of polymer to make 100 meters of fiber. Its simplified design also makes it easy to operate and maintain. The system consists of 2 single screw extruders connected to a spinneret block. Metering pumps are eliminated to reduce the minimum polymer requirements and maintenance. The extruders speeds are set to deliver the desired flow rates. Mechanical torque limiters are provided to prevent over pressure. Note that the simplified design means the tolerances of fiber properties (denier & bico ratio) are limited to +/- 5%.
It is easily disassembled for cleaning. In addition to the pack there are only 5 wetted parts to be cleaned with no blind passages. The machine is very versatile. With optional parts, the machine is convertible to run monofilaments, high temperature polymers, meltblown webs and spunbond webs in almost any cross section desired. Used for R&D about 3 years running trials 3 days/wk. No
longer needed for current operations. Some polymers from 20 lbs to gaylord size also available at additional cost.
The only known problems are the transducer wire connection on A side extruder sometimes cuts out at startup and customer has a new plug that needs to be soldered which is not a big issue.
Currently installed and can be started up with a few days notice.
