Device for controlling guiding tongues of a product diverter

In a rotary machine for processing a series of sheet-shaped products supplied at a rate which is synchronized with the machine cycles, a device for diverting the stream of products to processing directions in accordance with a desired mode of operation. The device includes at least one guiding tongue pivotably supported in the path of movement of the products. A cam disk attached to a driven gear is supported for rotation at a free end of a rocking arm whose other end is pivotably supported on the machine frame. A cam follower lever is spring biased into engagement with the cam disk and at its end is fixedly connected to the pivot shaft of the guiding tongue. The rocking arm is linked to a control device which either electrically or electromechanically by means of two solenoids sets the rocking arm in at least three different angular positions in dependency on the selected mode of stream diverting operation.
