Title:
METHOD AND APPARATUS FOR STICKING RIBBON-SHAPED RUBBER PIECE
Document Type and Number:
Japanese Patent JP2009000865
Kind Code:
A
Abstract:

To provide a ribbon-shaped rubber piece sticking apparatus which forms a ribbon-shaped rubber piece in a prescribed cross-sectional shape by passing the ribbon-shaped rubber piece between a pair of rollers and prevents the tip of the ribbon piece from being retained by a small diameter roller when it is held by a large diameter roller and stuck to a rotary support.

Reticulate knurling working is applied to the peripheral surface of the small diameter roller 2, and specular working is applied to the peripheral surface of the large diameter roller 3. A minute clearance by the knurling working is formed between the peripheral surface of the small diameter roller 2 and the ribbon-shaped rubber piece 9. Air is ejected in the tangent direction of the peripheral surface of the small diameter roller 2 from the nozzle of an air blow means 4 to make the air pass through the minute clearance. The ribbon-shaped rubber piece held on the peripheral surface of the small diameter roller 2 is peeled off by the air ejected from the nozzle 4.
