The wrap reel is used for making leas for strength testing, count testing, and for other chemical processing. The leas are either imperial leas having a swift perimeter of one a half yards with 80 turns, or metric leas having swift perimeter of one meter with 100 turns. Leas of other swift perimeters and number of turns may also be made for specific applications.
The Wrap Reel is offered in both motor and hand operated models. The yarn is spread uniformly in a band of 20 mm as the lea is formed. Up to 5 leas can be formed at one time. One of the arms of the reel can be docked to facilitate the removal of the leas from the reel. The number of turns is indicated on a re-settable mechanical counter.
