Abstract
Abstract In an apparatus for winding up a plurality of tape-like narrow yarn groups divided from sheet-like wide yarn group and treated in liquid, the apparatus comprises a first means and a second means. The first means is that of changing the direction of each liquid-treated tape-like narrow yarn groups at right angles with respect to the advancing direction of the tape-like narrow yarn groups. The second means is that of winding up each tape-like narrow yarn group on take up beams arranged with their axes being parallel to said advancing direction of the tape-like narrow yarn groups.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
158 words
In an apparatus for winding up yarns on respective take-up beams from a plurality of tape-like narrow yarn groups divided from a sheet-like wide yarn group after treatment in liquid, said apparatus comprising a first means for changing the direction of each liquid-treated tape-like narrow yarn group substantially at right angles with respect to the direction of travel of the sheet-like yarn group, and second means for winding up each of the tape-like narrow yarn groups on the take-up beams, said beams being arranged with their axes being parallel to said traveling direction of the sheet-like yarn group, said plurality of take-up beams being connected together to be moved simultaneously in the direction of travel of said sheet-like wide yarn group, said first means being diverging pieces provided at substantially 45* with respect to the direction of travel of said tape-like narrow yarn groups, whereby said yarn groups are diverged to both sides of the yarn advancing direction.
Claim 2
Dependent Claim
158 words
In an apparatus for winding up yarns on respective take-up beams from a plurality of tape-like narrow yarn groups divided from a sheet-like wide yarn group after treatment in liquid, said apparatus comprising a first means for changing the direction of each liquid-treated tape-like narrow yarn group substantially at right angles with respect to the direction of travel of the sheet-like yarn group, and second means for winding up each of the tape-like narrow yarn groups on the take-up beams, said beams being arranged with their axes being parallel to said traveling direction of the sheet-like yarn group, said plurality of take-up beams being connected together to be moved simultaneously in the direction of travel of said sheet-like wide yarn group, said first means being diverging pieces provided at substantially 45* with respect to the direction of travel of said tape-like narrow yarn groups, whereby said yarn groups are diverged to both sides of the yarn advancing direction.
Claim 3
Dependent Claim
22 words
An apparatus as claimed in claim 1 wherein each of said take-up beams is provided on a beam stand having four wheels.
Claim 4
Dependent Claim
19 words
An apparatus as claimed in claim 1 wherein each of said take-up beams is rotated by a torque motor.
Claim 5
Dependent Claim
19 words
An apparatus as claimed in claim 2 wherein said apparatus further comprises rails on which said wheels roll reciprocally.
Claim 6
Dependent Claim
32 words
An apparatus as claimed in claim 1 wherein said take-up beams are rotatably mounted along both sides of the extended axis of the direction of travel of said sheet-like wide yarn group.
Claim 7
Dependent Claim
40 words
An apparatus as claimed in claim 1 wherein said apparatus further comprises a pair of delivery rollers rotatably mounted between each of said diverging pieces and each of said take-up beams, said delivery rollers being driven by a torque motor.
