Sometimes it is necessary to reverse the rotation of the driven pulley wheel in relation to the driver pulley. If the driver is rotating in an anti-clockwise direction the driven pulley may be required to rotate in a clockwise direction. |
|
This is achieved by twisting the belt as shown in the diagram above. Care must be taken when this is done as the belt can rub where it crosses and this may increase friction or damage it. |
