| 摘要 |
The present invention relates to apparatus for edging reinforced elastomeric fabric and a preferred method for the operation thereof. One embodiment of apparatus includes a frame, a table for support of the elastomeric fabric, at least one extruder assembly adjacent the table for the application of a suitable elastomeric material directly onto an edge of the elastomeric fabric and means for moving the elastomeric fabric over the table. In an alternate embodiment, the apparatus includes a frame, means for support of the elastomeric fabric and at least one extruder assembly adjacent the means for support for the application of a suitable elastomeric material directly onto an edge of the elastomeric fabric. The preferred method includes the steps of passing the elastomeric fabric over the means for support, extruding the elastomeric material through the head and imparting a first edge therein compatible with an edge of the elastomeric fabric and joining the extruded material to an edge of the elastomeric fabric by forcing the material into substantially all of the exposed surfaces thereof. |
