Title:
STEAM DRAWING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/027698
Kind Code:
A1
Abstract:
The invention is a steam drawing device: which is provided with a steam chamber (10) into which pressurized steam is introduced, a first sealed chamber (2) adjacent to the thread inlet of the steam chamber, and a second sealed chamber (3) adjacent to the thread outlet of the steam chamber; and which applies pressurized steam and draws the running thread (Z). The steam chamber has a steam-introducing part (4) for introducing the steam. The first and second sealed chambers (2, 3) are each provided with a labyrinth seal (22, 32), in which each of multiple plate pieces runs from above or below the inner wall towards the thread. The steam drawing device has a first and/or a second thread position-restricting bar (8, 7), which keeps the running thread from contacting the plate pieces. Each thread position-restricting bar extends in a direction that is horizontal and orthogonal to the thread running direction, and is disposed on the side opposite the steam-introducing part (4) with the thread therebetween.
