SUMMARY OF THE INVENTION The present invention relates to a pad cloth feeding device for gripping a pad cloth on a pad cloth receiving plate along a lower side surface of a flat pad cloth ruler and transferring it to a sewing table. The above-mentioned object is achieved by providing an air outlet that is parallel to the upper surface of the ball cloth ruler and forms an air flow outward from the center of the ball cloth ruler.

According to a second aspect of the present invention, the upper side surface of the bedding ruler is attached to a tip end of a plate-shaped binder substrate which is substantially orthogonal to the upper surface, and the air flow outlet is provided along the side surface of the binder substrate. In order to achieve the above object, the air is blown toward the upper side surface.

Further, the invention according to claim 3 achieves the above object by forming the air outlets on the pipes arranged on both sides of the binder board and into which the pressurized air is introduced.

[0013]

In the present invention, since the air flow is formed in parallel with the upper surface of the pad cloth ruler and outward from the center of the pad cloth ruler, the ball caught on the lower surface of the pad cloth ruler. The cloth is lifted by the lift created by the air flow,
Both ends thereof are prevented from being caught in the lower side.

According to the second aspect, since the air flow from the air outlet is blown out along the side surface of the binder substrate and is redirected along the upper side surface of the pad cloth ruler, it is caught by the pad cloth ruler. Lifting force that sucks up both ends of the existing bedding is easily generated.

According to the third aspect, since the air outlets are arranged on both sides of the binder substrate, the distance between the air outlets and the cloth changes when the pad cloth moves together with the pad cloth ruler. Therefore, there is no need to change the amount of blown air when moving the cloth.
