AI Technical Summary
During tire manufacturing, the deformation of the rubber pads due to the curling effect during storage can affect the tire's dimensional accuracy and fit, potentially leading to defects such as shoulder cavities and shoulder bulges, thus reducing the tire's structural strength and safety.
The pad is made of support strips, which have inflatable and deflated support cavities. The support strips are spaced apart along the length of the pad. The main body of the pad is composed of polyurethane and polyester filament layers. The air pressure of the support cavity is controlled by a pneumatic slip ring to eliminate interlayer compression deformation. The pneumatic slip ring also enables the controllable expansion and collapse of the support cavity.
It effectively eliminates deformation of the rubber mat during winding and storage, improves tire quality stability, eliminates safety hazards, and increases the service life and winding length of the mat.

Abstract
Claims
1. A drape, characterized in that, The device includes a pad body and supporting rubber strips. The supporting rubber strips are made of elastic material and have a support cavity that can be inflated and deflated. The top of the support cavity protrudes from the surface of the supporting rubber strip when it is inflated. The supporting rubber strips extend along the length of the pad body and are arranged in several intervals along the width of the pad body. The space between adjacent supporting rubber strips is formed for placing the pad.
2. The drape of claim 1, wherein, The main body of the pad is made of polyurethane, and its upper and lower surfaces are provided with polyester filament layers.
3. The drape of claim 1, wherein, One end of the support cavity is a closed end, and the other end is an open end, which is connected to an external air source.
4. The drape of claim 3, wherein, The support strips located on one or both sides of the support cavity are recessed to form grooves.
5. The drape of claim 1, wherein, An adhesive layer is provided between the supporting rubber strip and the padding body.
6. The drape of claim 4, wherein, The bottom of the groove is connected to the main body of the pad by sewing with curtain thread.
7. A drape crimping device characterized by, The device includes a pad winding wheel and a pneumatic slip ring. The pad winding wheel has a pad as described in any one of claims 1-6 wound on it, and the support cavity is in a deflated state. The rotor end of the pneumatic slip ring is connected to the spindle of the pad winding wheel, and the stator end of the pneumatic slip ring is connected to an external air source and the support cavity, respectively.
8. The doily crimping device of claim 7, wherein, The stator end of the pneumatic slip ring is provided with an air inlet and an air outlet. The air inlet is connected to the external air source through an air inlet pipe, and the air outlet is connected to the support cavity through an air outlet pipe. A control valve is provided on the air outlet pipe.
9. The doily crimping device of claim 7, wherein, It also includes a base frame, and the pad fabric curling wheel is rotatably mounted on the pad fabric curling bracket, which is connected to the base frame.
