The processing drum, rotatable about the axis for processing printing products, has advancing means for the step-by-step advancing of the printing products deposited in a straddling manner on the rests. In the upper region of the circulating path, these advancing means perform a working stroke about the axis and in the lower region a return stroke. The processing drum has a drawing member reaching around it from below on which, drawing member holding members are arranged at the spacing (A) of the rests, in ordex to prevent the printing products from falling down when they pass through the lower part of the circulating path and at the same time to support the elongate processing drum.

Why it's free to use
- Filed January 4, 1993 and granted March 30, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 4, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 4, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
