Description

[Detailed Description of the Invention] This invention relates to a dividing frame in a sizing machine that divides undried sizing warp into two upper and lower sheets.

Conventionally, when forming a large number of warp threads into a sheet and drying the warp threads with sizing using a sizing machine, sizing was performed using combs or grooves after drawing to achieve sizing that was well-sorted and fluffed. The condition is that the adjacent warp threads are passed through rollers or the like so that they do not come into contact with each other and are dried in a completely separated state.

In this case, in order to improve efficiency by arranging as many yarns as possible, the pitch of the comb and groove rollers becomes smaller.

For this reason, it takes time and effort to thread each warp thread through the comb.

In addition, there were also drawbacks such as knots in the thread and adhesion of scale, which caused the thread to become looser than expected, resulting in thread breakage.

The purpose of this invention is to arrange the warp sheets squeezed by the squeeze roller in a cylinder of a drying device or a hot air drying section so that each warp yarn is separated at equal intervals, and then to fluff them and then dry them. Between the drawing roller and the cylinder or guide roller, the warp sheet is divided into two parts using a dividing frame with one thread.
The purpose is to divide the warp sheets and insert one warp thread of each warp sheet into each thread groove of the divided frame, arrange the warp threads at equal intervals, and fluff them in the thread grooves.

At this time, the thread pitch of the split frame can be twice the pitch between the warp threads in the drying section, so the warp threads can be easily inserted into the thread grooves of the split frame, and the thread grooves are V-shaped. Therefore, it is an object of the present invention to provide a dividing frame that can perform good fluffing without causing yarn breakage due to knots, scales, etc.

Embodiments of this invention will be described below with reference to the accompanying drawings.

In the figure, A is a divided frame, and the outer peripheral surface of this divided frame A is formed with a screw thread 1.

As shown in FIG. 1, the use of the above-mentioned dividing frame A is carried out between a sizing device B and a drying device C that dries a large number of sheet-shaped warp threads a that are sung by this sizing device B. It is interposed between two divided sheet-like warp threads a.

Further, the end of the divided frame A is supported by a bearing 2, and the divided frame A is rotated approximately 200 degrees forward and backward by a driving device 3.
Alternate reversals.

The use of the split frame according to this invention will be explained based on the above-mentioned configuration. The sheet-shaped warp a is guided into the size solution of the size tank 12 of the size application device B by the guide roll 11, and then The paste is passed between the squeezing rolls 13 to remove excess size liquid.

The warp threads a after sizing are then guided from the guide rolls 14 to the drying drum 15 of the drying device C and dried.

The sheet-like warp a between the squeeze roll 13 and the guide roll 14 is divided into two parts, and a dividing frame A is interposed between the two-part sheet-like warp a.

At this time, the warp threads a are fitted into the screw grooves on the upper and lower surfaces of the divided frame A, one by one.

As described above, according to the split frame according to this invention, each of the sheet-like warp yarns divided into sheets is fitted into the single thread groove on the upper and lower peripheral surfaces of the split frame, so that the number of grooves is reduced. is the number of threads (because the sheet is divided into two and the grooves on the top and bottom sides of the screw are used).

Further, when the warp threads that have passed through the dividing frame are combined by a guide roll or a drying drum, the warp threads are arranged in parallel at equal intervals at a pitch between the screw pitches, so that they do not overlap.

Since it is a one-round thread, the pitch can be wide, and since it is a thread, it is easy to insert the warp threads into the grooves, and even if they are inserted incorrectly, it is easy to correct.

In addition, since it has a ■-shaped groove, there is no clogging due to thread knots, threads, etc., and there is less thread breakage.

In particular, since the dividing frame is alternately rotated forward and reverse, it is self-cleaned by the threads and no glue residue adheres to it, and there is no thread breakage due to glue residue.
There is no movement of the entire seat (in a direction transverse to the direction of travel of the seat).

Furthermore, since the groove has a lead, the fluffing effect is much better, and the screw groove is easier to manufacture and handle than conventional combs and grooved rollers.

In addition, since it is a lot type, it can be made hollow and water-cooled.
