ABSTRACT:
The knotter clutch control prevents the driven dog of the clutch from flipping out into its actuated position for engagement with the driving lug of the clutch unless the lug is in a position wherein positive driving engagement between the lug and the dog is assured. A strategically positioned control lobe on the cam ring of the drive sprocket for the clutch blocks release of the dog into its extended position when the driving lug is at the lug pickup point on its path of travel. The dog is free to be released when the lug is at all other positions on its path of travel so as to be in position for engagement with the lug when it next arrives at the pickup point. The dog is reset into its retracted position after a single revolution of the knotter drive shaft.
