Warping/Beaming

 

               

 

Description of the process

There are several basic methods used to produce beamed yarns/strands:

  • DIRECT WARPING:  Used mostly for electronic applications. A large and predetermined number of ends pulled from a creel are wound onto a large spool (beam) and placed on a warper to produce section beams. Then a predetermined number of them are assembled on a slasher to generate a loom beam, which will be used in the next processing step. During the slashing operation, a secondary sizing is applied to the ends in order to enhance their abrasion resistance. Some applications don't require the slashing operation; section beams can be used directly in the next textile process or a determined number can be assembled on a beamer to make up a loom beam.
  • SECTIONAL WARPING:  A sheet of ends, pulled from a limited number of packages, is placed on a creel and wound onto the cylinder of the sectional warping machine in order to build a section. When the required amount of warp end sheets necessary to achieve the desired fabric width have been completed and placed side by side, all of the sections are rewound directly on a beam, creating the loom beam.
  • WARPING SIZING:  A predetermined number of ends pulled from a creel are directly slashed and wound onto a beam. Then the slashed section beams are assembled together on a beamer to produce the loom beams.

NOTE:  Some applications using warp ends don't utilize beams. Instead, the textile process is directly fed from a creel.
