The needle of system 328 FL-E has a normal round point for working woven and knit fabrics. It is used in industrial lockstitch and general-purpose sewing machines, here mainly for technical applications such as quilting rather than classic garment production. Suitable machine classes are found, among others, at H.J.Dahmen Steppomat-Textilmaschinen (classes ECOMAT, ECOMAT SERIE ET DOPPELNAHT AUbisM, STEPPOMAT SERIE G, STEPPOMAT SERIE GT DOPPELNAHT AUbisM) and Dahmen (classes ECOMAT, ECOMAT SERIE ET DOPPELNAHT AUTOM, STEPPOMAT SERIE G ALL CLASSES, STEPPOMAT SERIE GT DOPPELNAHT AUTOM).
The available needle sizes are used, among others, for heavy, multi-layer woven and knit fabrics as well as technical textiles. As sewing thread, a matching thickness is usually recommended depending on the needle size chosen, e.g. from Amann Serafil (polyester) or Rasant (polyester/cotton); for heavy-duty use, a bonded nylon thread.
