2. Description of the Related Art A conventional example for desizing and scouring and bleaching (pretreatment) a long fabric produced industrially is to wash the fabric after the hair-burning treatment, and then desizing and scouring the fabric. The chemical solution for is applied at room temperature, and then the cloth provided with the chemical solution is passed through a preheating steam zone such as a J-type box, a U-type box, and an R-type box, which are installed in a wet heat reaction tower, The fabric is heated, and then, it is shaken in the liquid in the moist-heat reaction tower so as to be stacked and sequentially retained, and the steam and the hot liquid at the time of the residence are used together to remove the desizing by the wet heat action for about 60 minutes. It is a refining reaction.

That is, as a concrete example of the pretreatment device of the conventional example, there is a structure as shown in FIG. 1, in which 1 is a treatment liquid impregnation tank, 2 is a liquid-impregnated cloth 3 in the upper part of the wet heat reaction tower 4. Timing zone for heating timing in the moist heat atmosphere of No. 5, 5 is a shake-off mechanism for shaking off the cloth that has passed through the timing zone 2, 6 is a rotating drum arranged in the wet-heat reaction tower 4, 7 Is an endless conveyor that forms and holds a substantially U-shaped cloth passage 8 between the peripheral surface of the rotating drum 6 and the cloth passage 8. The cloth passage 8 is located in the liquid tank 9. ..

The cloth 3 to which the chemical has been applied in the treatment liquid impregnation tank 1 has a swinging mechanism 5 after the chemical has penetrated into the core of the cloth at the timing of the timing zone 2.
By this operation, the cloth is fed into the cloth passage 8 formed by the drum 6 and the conveyor 7 in a superposed state by being shaken off. The fabrics supplied in the fabric passage 8 in an overlapping state are driven by the driving force of the drum 6 and the conveyor 7 to form a liquid tank 9
It is sent to the inside of the liquid, and while passing through the liquid, a wet heat reaction treatment is performed to pretreat the cloth.

However, in such a conventional pretreatment apparatus, the cloth 3 which is swung in the zigzag shape into the passage 8 by the shaking mechanism 5 is shaken down by its own weight as shown in the drawing. For example, in the case of chlorite treatment (bleaching), the fabric is less likely to slip due to the chemical solution, which causes unstable formation of the zigzag-shaped overlay. As shown in FIG. 2, it becomes difficult to incline in the width direction of the cloth 3 and to supply the cloth 3 in the cloth passage 8 in an orderly zigzag state, and when the cloth 3 becomes steep in the width direction,
There has been a problem that the cloth is entangled in the passage 8 and causes a trouble that the cloth cannot be smoothly transferred.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in FIGS. 3 and 4. The same parts of the structure of this embodiment and the structure described in the conventional example are used in the conventional example. In FIG. 3, the reference numerals are given and the description of the same structural parts is omitted. In the vicinity of the cloth supply port of the cloth passage 8 formed by the rotating drum 6 and the endless conveyor 7, the cloth is sewn by the swinging mechanism 5. A support shaft 11 positioned in a direction parallel to the width direction of the cloth 3 which is folded and supplied into the passage 8 is rotatably held, and a side road door type is provided at three longitudinal positions of the support shaft 11. The holding arm 12 is fixed. A connecting arm 13 is fixed to one end of the support shaft 11, and a tip of a crank arm 15 driven by rotation of a motor 14 is connected to a tip of the connecting arm 13. Therefore, when the motor 14 is rotated, the pressing arm 12 is reciprocally rotated within a range of about 90 degrees.

As described above, in this embodiment, the pressing arm 12 is provided in the vicinity of the cloth supply port of the cloth passage 8 so that the upper end of the cloth loaded by being swung to the cloth supply port is set to the above-mentioned value. Since it can be intermittently pressed by the operation of the pressing arm 12, the overlapping state of the cloth folded and overlapped in the cloth passage 8 by the shaking mechanism tilts in the width direction of the cloth as shown in FIG. Even in such a superposed state, by rotating each of the pressing arms 12 from the position shown by the chain line in FIG. 3 to the position shown by the solid line, the loading upper end surface of the fabric is pressed into a substantially horizontal state and shaped. To be done.

Immediately after the shaping, the motor 14 is reversely rotated to return the pressing arm 12 to the base position shown by the chain line so that the cloth 3 is continuously loaded. Therefore, by intermittently rotating the pressing arm 12, the cloths stacked at the cloth supply port of the cloth passage 8 can be pressed and shaped so as to be in a substantially horizontal state.
The cloths sequentially fed into the cloth passage 8 formed by the conveyor 7 and the conveyor 7 are kept in an orderly overlapping state,
As a result, the smooth transfer of the cloth in the reaction tower 4 and the wet heat reaction treatment are carried out uniformly and effectively over the entire surface of the cloth.
