The Detwister is Used to Remove Twist to openning the fabric after dyeing

The detwister is used to remove twist from rope fabric.detwister The slitting and spreading machines are designed to turn the wet  fabric in rope form into a web form that can be fed into the automatic slitter and then deposited onto a movable plaiter. This process also eliminates the bulk of the impregnation liquid. This untwisting is accomplished by a ring guider arrangement that rotates as the fabric moves through it. This rotation, synchronized with the detwister, untwists the fabric prior to its entrance into the detwister, thereby preparing the fabric for slitting and spreading.

In a particularly preferred embodiment, the upper level detwisting mechanism is in the form of a conventional poteye which is widely employed as a guiding element and which can be obtained at a relatively low cost.detwister The poteye is a ring-shaped member having an upper and lower flange with an intermediate annular recess. The detwisting mechanism of the invention comprises a pair of resiliently biased, opposed rollers that grip the underlying woven cloth and a reversible drive motor for engaging the opposite rollers.

A sensor element, disposed to sense the direction of fabric twist, is provided in close proximity to the ring guiders and functions to detect the accumulating twist in the advancing fabric as it travels through the ring guides.detwister The sensing element signals the reversible drive to immediately move in the direction of the fabric twist to disengage and remove the twist. This enables the slitter to be positioned and operated in a time period that minimizes the risk of damage to the slitter and the fabric as it is being moved to the slitter by the reversing drive.

It is also advisable to install a safety shut-off device, incorporated with the upper level detwisting mechanism and which operates in the event of a knot or severe tangle in the fabric rope to shut off operation of the drive for the lifting roller.detwister This prevents the knotted or tangled fabric from being drawn up into the detwisting mechanism, where it could damage such equipment or potentially be snagged on and damaged by the poteye 63.

This detwister is a good choice for  opening machine with rope detwisting,automatic tube slitting and web guiding with spreading.detwister The bianco detwister is also easy to maintain and clean with a simple design. This is why you can trust the detwister from Erhardt+Leimer to give you years of reliable service. Please don't hesitate to contact us if you have any questions. We look forward to hearing from you!
