Mikrosam produces a range of slitting and rewinding equipment for composite prepregs: UD thermoset, thermoplastic, dryfiber, and fabric.
Our machines allow customers to save costs by acquiring large width raw material from suppliers and preparing narrow tapes on-demand.
We pioneered the small-scale slitting and rewinding equipment for R&D departments. Now, we offer high ROI complete units for large-scale conversion of raw composite material together with inspection systems.

MikroInspect
Automatic Online Inspection System
This is unique technology developed by Mikrosam for online inspection and automatic detection of the errors on the slit tape before it is re-wound on the spool. It is developed by constant input by customer requirements for increasing demand of high-quality error free slit tape that in later stage can be processed in Automated Fiber Placement (AFP) orAutomated Tape Laying (ATL) machines.
The list of errors that are detected and recorded by IPLIS are:
- Width-out of tolerance
- Tow thickness-out of tolerance–tow profile measurement principle
- Fuzz detection
- Foreign object detection
- Splice position detection
All detected errors are continuously detected in the QCS System.
