Device and method for transporting and separating blanks of a material web

Abstract

The invention relates to a device (100) for transporting and separating blanks (1010) from a material web (1000) with a vacuum cylinder (8) for transporting the blanks (1010), a vacuum transport cylinder (7) for further transporting the blanks (1010), wherein the vacuum cylinder (8) and the vacuum transport cylinder (7) are each equipped with their own independent drive motor (84), and with a control unit (9) to which the drive motor (84) is connected via a data link. According to the invention, speed profiles for the rotation of the vacuum cylinder (8) are stored or can be generated in the control unit (9), and the vacuum cylinder (8) can be rotated with a speed profile with different rotational speeds (R). The invention also relates to a method for transporting and separating blanks from a material web. A device and method enable a gentler and more accurate transfer of blanks from a vacuum cylinder to a vacuum transport cylinder.
