Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for processing tubular woven fabric, and in particular, it is used to process knitted tubular woven fabric that is twisted into a rope shape after dyeing, washing, etc. for the next finishing treatment. The present invention relates to a device for transforming a flat tube without twisting.

When dyeing and finishing tubular knitted fabrics, continuous and batch operations are combined.

For example, today machines have been developed that can continuously dye and wash tubular knitted fabrics in a short time and at high speed.
When the tubular fabric is finally washed, it will be wet, twisted,
Moreover, it is in the form of a long and thin rope.

For further processing of this tubular fabric, such as drying, resin treatment, or longitudinal shrinkage to return it to its initial loop shape, it is untwisted and unfolded to a substantially untwisted flat state. need to be supplied.

A prior art device for treating this fabric is Knias, US Pat. No. 2,110,520, which includes a floating frame mounted within a tubular fabric.

The floating frame includes a stem having an end roll that engages the inner surface of the tubular fabric and a pair of arms resiliently attached to the stem that expand rearwardly from a front roll that expands the fabric. ing.

Attached to the rear end of the stem are a pair of rolls housed between a pair of drive rolls on the outside of the tubular fabric.

Although this Knias patented device is widely used today,
The processing speed of this device is extremely slow and requires constant monitoring by Iruma.

The slow processing speed is a major disadvantage as other processes and subsequent steps have been improved to be much faster than the speed at which tubular fabrics can be untwisted and unrolled in Knias-type equipment. It has become.

It is an object of the present invention to provide an improved device for untwisting and unrolling tubular fabrics.

Furthermore, it is an object of the present invention to provide an apparatus which can reduce the amount of human assistance and greatly increase the speed of deforming the fabric.

The apparatus of the invention includes a frame and support means mounted on the frame including at least one pair of drive rolls driven in opposite directions and spaced apart from each other in a common plane.

A pair of rings are provided between the drive rolls, and these rings are supported in contact with each drive roll in opposite directions within the plane.

The abutment holding means includes running means for rotating each ring about their center as the drive roll rotates.

A front arm and a rear arm extend from each ring.
Each arm is pivotably movable relative to the ring center in said plane and is adapted to engage the inner surface of the tubular fabric.
