What is Looming ?

Looming:

Looming covers the process involved in warp preparation after sizing up to setting them to loom. The process can be shown as follows:

Drawing-in → Warp Tying →Loom



Drawing-In:

The process of drawing every warp end through its drop wire, heddle eye and reed dent can be performed manually or by means of automatic machines.In both case,a length of warp yarn,just enough to reach to the other side of the frame, is unwound. Leasing (i.e. selecting warp) of the warp at this stage simplifies the separation of the yarns. Then they are threaded through drop wires heddle eyes and reeddents.The automatic drawing machine can handle the leasing-in and drawing-in process in one single operation.



Tying-In:

When fabric of a particular type is being mass-produced, the new warp beams will be identical with the exhausted beams on the looms.Therefore,if every end on the new beam is tied to its corresponding end on the old beam, the drawing-in process can be omitted. Tying-in may be done by means of a small portable machine on the loom or as a separate operation away from the loom.
