TECHNICAL FIELD OF THE INVENTION
The present invention relates to a front roller for winding a woven fabric woven by a hand loom and a back roller for winding a number of warps.
[0002]
[Prior art]
As shown in FIG. 6, a conventional hand loom w includes a front roller m for winding a woven fabric and a back roller n for winding a number of warp (warp) yarns x. The heald and the weft are arranged in parallel to the side frame k so as to be rotatable, and pass through the warp x through the through hole e and the gap c every other one to divide the warp x vertically. ) A heddle a having two functions of a reed into which a thread is driven is one of an upper position {1}, a lower position {2}, and a rest position {3} provided on the support piece l of the side frame k. So that both ends thereof are mounted and held. A state in which the front portions of a large number of warp yarns x wound around the back roller n are tied and fixed to the sticks o attached to the front roller m with the strings p via the heads a and the warp x is stretched , The weddle a is alternately moved to the upper position {1} or the lower position {2}, and the weft is inserted through the shuttle s around which the weft y is wound in the yarn path generated at that time, and the inserted weft y is transferred to the heddle a. The weaving is performed by repeating a series of operations of pulling the weft yarn y into the warp x by pulling it toward the front roller m.
The way of attaching the warp x to the back roller n is performed by knotting or winding one end of the warp x on a stick attached with a string (not shown), as in the case of the front roller m. .
[0003]
[Problems to be solved by the invention]
As preparation before weaving by the conventional hand loom w described above, it is necessary to set a warp between a front roller and a back roller. For this purpose, first, a stick is attached to the back roller n with a string, and one end of the warp x is tied or wound around the stick, and all the warps x of a predetermined length are wound around the back roller n while being tensioned. Then, the front portions of all the warp yarns x are passed through the gap c of the head a and every other hole through the through hole e, and four warp yarns x are tied and fixed to the stick o attached to the front roller m with the string p. Then, the front roller m is rotated until the stick o overlaps the roller m, so that the warp x is taut. The preparation is completed as described above, but the work of setting the warp x on the front roller and the back roller described above can be said to be very troublesome and troublesome.

[0016]
Next, how to use the front roller 10 and the back roller 30 configured as described above will be described in relation to the operation of the hand loom.
(1) First, the required number of warp yarns x of a required number corresponding to the width of the fabric is set on the back roller 30. Specifically, the cover 37 of the back roller 30 is removed, and one end of each of a large number of warps x is passed through each small gap 35 of the shaft 31 so as to extend to the upper surface 31a, and then the cover 37 is fixed. Tighten it with the screw 42 and attach it. At this time, each warp x is pressed and fixed by the rubber member 40 attached to the cover 37.
(2) Then, with the pawl 47 of the ratchet mechanism 45 removed from the pawl wheel 46, the knob 48 is turned to wind all the warp yarns x around the back roller 30 while tightening them. After the winding of the warp x is completed, the claw 47 is engaged with the claw wheel 46 again so that the warp x is not sent out.
(3) With the second holder 55 of the head 50 removed, only the first holder 51 is placed on and held at the respective rest positions (3) of the support pieces 4, 6 of the side frames 3, 5, and the back roller is set. The front portions of all the warp yarns x wound in parallel with 30 are passed through each longitudinal groove and the gap of the first holder 51 so as to be placed every other one from the top. Next, the second holder 65 is attached to the first holder 51 to be integrated.
(4) The other end of the warp x passed through the heddle 50 is fixed to the front roller 10 in the same manner as the attachment to the back roller 30. At that time, each warp x is pulled by hand in a state where the claws 27 and 47 are respectively engaged with the pawl wheels 26 and 46 of the ratchet mechanisms 25 and 45 so that the rollers 10 and 30 do not rotate inward. The tightening of the fixing screw 22 is performed while adjusting the tightening of the fixing screw 22 so that all the warp yarns x are in a taut state.
(5) The shuttle shown in FIG. 5 in which the heddle 50 is alternately moved to the upper position (1) and the lower position (2) of the support pieces 4, 6 and the weft yarn y is wound on the yarn path generated at that time. The weft is inserted through 70, the inserted weft y is pulled toward the front roller 10 by the heddle 50 removed from the support pieces 4, 6, and the weft y is woven into the warp x.
[0017]
As described above, according to the heddle of this hand loom, even a beginner can easily perform a preparation operation before weaving for attaching a warp to each roller.
