BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for feeding out a cloth in a reversing machine for laminating a cloth on a reversing table.

[0002]

2. Description of the Related Art A spreading machine that stretches a fabric in a stack and feeds it to a cutting machine is equipped with a rolled original material on a traveling cart that reciprocates in the longitudinal direction on an upper surface of a spreading table. Then, the raw material is guided to a cloth feeding port provided in the cloth feeding portion, and the cloth is fed from the cloth feeding port to the upper surface of the spreading table in accordance with the traveling of the traveling vehicle, and the reverse portion of the traveling vehicle, that is, the fabric is rotated. Cut the fabric by holding the cloth at the folded part and moving the cutter in the direction perpendicular to the running direction of the moving carriage, move the moving carriage to the reference position while holding the cloth end, and then re-roll the material. Is known in which a traveling trolley is run while unwinding a fabric, and the fabric is placed on the upper surface of a spreading table so as to be stretched.

[0003]

In the above-mentioned conventional reversing machine, the interval between a pair of guide plates provided for guiding the fabric to the feeding port is set to be relatively small, and is set so as to be further narrowed at a portion on the feeding port side. Since the end of the raw fabric is difficult to pass through here and easily stays, every time the raw fabric is changed, the end of the raw fabric is manually drawn through the space between the guide plates and drawn out to the payout opening, There was a problem that the operation efficiency of the reversing machine was greatly reduced due to the troublesome work.

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above problems, and it has been proposed that the end of the fabric can be easily inserted while maintaining good guiding performance of the fabric, thereby reducing the operating efficiency of the reversing machine. It is an object of the present invention to be able to prevent the problem.

In order to achieve the above object, a cloth feeding device in a reversing machine according to the present invention is arranged such that a traveling carriage is reciprocally slid in a longitudinal direction of the reversing table so that the cloth is stacked on the upper surface of the reversing table. In the reversing machine to be placed, the cloth feeding portion includes a cloth feeding port formed at a lower portion, a guide plate for guiding the fabric to the cloth feeding port, and a suppression plate disposed to face the guide plate. The suppression plate is characterized in that a part thereof is configured to be swingable in a direction in which it is brought into contact with and separated from the guide plate by the driving means.

Further, a spreading roller is provided between the guide plate and a cloth feeding port formed below the cloth feeding section,
It is also characterized in that the contact pressure of the fabric abutting on the spreading roller can be adjusted by a suppressing plate which is swung by the driving means.

One of the features of the restraining plate is that a guide portion for guiding the fabric is formed in an upper portion thereof and a pressing portion for holding the fabric is formed in a lower portion thereof.

[0008]

When the end of the fabric placed on the traveling cart is drawn out from the fabric feeding port, first, the traveling cart is moved from one end side in the longitudinal direction of the extension table to the reference position of the fabric on the other end side. While traveling, the restraining plate is swung in a direction in which the restraining plate is separated from the guide plate, and the end of the fabric is hung between the separated guide plate and the restraining plate. Is fed to the delivery port.

[0009] When the cloth fed to the pay-out port extends to the upper surface of the spreading table in this manner, the restraining plate is swung in the direction approaching the guide plate by the driving means, and then the cloth is moved from the pay-out port to the traveling carriage. The running carriage is caused to run in the longitudinal direction of the spreading table while being extended in accordance with the running speed of the spreading table to spread the cloth. At the time of the spreading, the waving and flapping of the fabric are appropriately suppressed by the suppressing plate, so that the stretched fabric can be spread without wrinkling.

When the traveling bogie is at the end of the extending fabric and cuts the fabric in order to align the extending direction of the fabric, the holding member is swung by the driving means so that the pressing member abuts the guide plate.
The cloth is sandwiched between the suppression plate and the guide plate, and the lower portion is cut with a cutter. At this time, in the case where the pressing member is provided on the suppressing plate via the elastic member, the pressing member gently abuts the receiving plate portion, so that the pressing member and the receiving plate portion abut on the entire surface without hitting each other, and It holds the edges soft and firm.

[0011] Thereafter, the traveling cart is turned over to the reference position side of the fabric while the end portion of the fabric is held at the payout opening, and when the traveling cart reaches the reference position of the fabric, the fabric is fed from the payout opening. It will be prolonged again. Thereafter, the cloth is repeated by repeating this.

In the case where the cloth is folded back in a zigzag manner without cutting the end, the end of the folded cloth is pressed by a catcher, and the traveling carriage reciprocates while feeding the fabric from the feeding port.
