ABSTRACT:
Flexible, sheet products which are to be opened have a first product part and a second product part. The product parts are connected to one another at a connecting edge, and the first product part has a border region which projects beyond the second product part. The products are conveyed with a leading edge running obliquely with respect to the conveying direction. An end section of the leading edge abuts a fixed stop wherein the first product part is arched in a lateral corner region. This results in the second product part lifting off from the first product part so as to define an opening. As the products are further conveyed, a holding-open element is inserted into the opening to maintain the first product part separate from the second product part. After the arching operation, the first product part springs over the stop and is further conveyed with the second product part.
